B&B Renovation Cost on Lake Garda in 2026: Real Prices per m²

"How much does it cost to renovate a B&B on Lake Garda?" If you are turning part of your home into a bed and breakfast in Riva del Garda, Arco or Torbole — or doing up a property you already run — it's the right question to ask before you even choose the tiles. The honest answer is: it depends, but in a predictable way. In 2026, renovating a B&B on Lake Garda costs between €500/m² for a refresh and €2,000/m² and beyond for a full job with new rooms and bathrooms — a little more than an ordinary home, because you have guest rooms with en-suites and a breakfast area, but far less than a hotel, because a B&B in Trentino is limited to a handful of rooms and stays below the heavy regulatory thresholds. This guide gathers the figures we use in real quotes: no price lists, just numbers from the site.

How much per square metre? The 4 levels of intervention

A B&B is a hybrid: partly your home (kitchen, living area, perhaps your own private flat), partly a small hospitality business (guest rooms, dedicated bathrooms, breakfast room). That's why the costs sit between residential and hotel work. As always, there is no such thing as "a renovation" — there are four levels with different budgets, timelines and results.

Level	Cost per m² (2026)	What it includes	Duration
Refresh	€500 — 800/m²	Painting, textiles, new lighting, bathroom touch-ups, room furniture	4-7 weeks
Light renovation	€800 — 1,300/m²	New bathrooms, floors, kitchen/breakfast area, partial systems, air conditioning	9-14 weeks
Full renovation	€1,300 — 2,000/m²	Demolition, redistribution, new systems, en-suite bathroom for every room, mid-to-high finishes	16-24 weeks
Premium / conversion	€2,000 — 2,800+/m²	Change of use, bespoke rooms, premium materials, home automation, B&B identity	24-34 weeks

For an external reference: Horwath HTL, which publishes the cost-per-m² benchmark for the hospitality sector, reports a national average of €1,300/m² for renovations in hospitality and €1,729/m² for historic properties with heritage constraints. A family-run B&B typically sits in the lower half of this range, because the most expensive hotel works — heavy fire-safety, lifts, dozens of identical bathrooms — are absent or much reduced here. The figures from local builders between Riva del Garda, Arco and Torbole are consistent, with a small premium (5-10%) for areas near the protected historic centre.

What each level really contains

Refresh (€500-800/m²). This is the "stop the ageing" level: complete repainting, new textiles in the rooms (blackout curtains, bedspreads, cushions), replaced lighting, upholstered headboards, bathroom touch-ups keeping tiles and sanitaryware, a refreshed breakfast area. It doesn't touch systems or layout. Just right when the building is sound but your Booking photos are eight years old.

Light renovation (€800-1,300/m²). Now things get serious. Room bathrooms completely redone (glass shower enclosures, wall-hung sanitaryware, branded taps), new floors, replaced kitchen or breakfast corner, electrical system brought up to standard with USB sockets at the bedsides, updated air conditioning, light soundproofing between rooms. The plumbing and heating are touched only where needed.

Full renovation (€1,300-2,000/m²). This is the level for someone who buys an old building on Lake Garda to turn it into a B&B, or who wants to bring a dated property up to 2026 standard. Partition walls are demolished to create an en-suite bathroom in every room — the move that, more than any other, lifts the rate and the review score — all systems are redone (electrical, plumbing, heating with heat pump, possibly mechanical ventilation), new floors, mid-to-high finishes, and a proper breakfast room, which is the second most photographed space after the bedroom. This is the level where most of our B&B quotes end up.

Premium / conversion (€2,000-2,800+/m²). Here we're talking about a change of use (from residential to hospitality, with all the relevant paperwork), bespoke-designed rooms, premium materials in the places that show, automation for lighting and climate, and — above all — a recognisable identity for the B&B: a coherent aesthetic direction that sets the property apart from the thousands of anonymous rentals on the lake. It's the intervention with the highest return, but it calls for real design work, not a furniture order form.

What really drives the price

Same building, same number of rooms, two quotes that differ by 40%. Why? Eight factors, in order of real impact for a B&B.

1. Number of en-suite bathrooms to create. This is the item that separates a B&B from an apartment. Each new bathroom carved out of a room costs €6,000-11,000 between demolition, new drainage, waterproofing, tiles, sanitaryware and taps. On a 4-room B&B, going from shared bathrooms to four private ones can be worth €30,000-44,000 on its own. It's the first thing to design well: a smart, repeatable bathroom layout slashes the cost.

2. Starting condition of the building. A 1960s-70s building with original systems, screeds to break up and plaster to strip costs 20-30% more than a 2000s one that just needs refreshing. At the survey we check the electrical panel (if it's ceramic with screw-in fuses, that always means €5,000-8,000 more in systems), the state of the walls, rising damp on the lower floors.

3. Change of use. If you convert a home into a hospitality business, you need specific permits and sometimes adaptations (minimum ceiling heights, ventilation, ASL health-and-hygiene requirements). Count €2,000-5,000 of additional paperwork and a few extra weeks. If instead you stay within the Province of Trento's "B&B in your own home" model — up to 4 rooms and 8 beds, with the family residing in the building — the regulatory impact is much lighter.

4. Level of finishes. Tiles at €20/m² versus €80/m² versus €180/m². Laminate flooring at €25/m² versus oak at €95/m². Taps at €80 versus €350. On a 150 m² B&B these choices make the difference between €120,000 and €220,000 — same floor plan, same systems.

5. Soundproofing between rooms. In a B&B the quiet room is the difference between a 9 review and a 9.5. In 1970s-80s buildings with light partitions, noise travels. Treating the dividing walls and noisy drainpipes during the renovation costs relatively little; doing it afterwards is nearly impossible.

6. Location and site access. The historic centre of Riva del Garda means restricted-traffic zones, no large lorries, materials carried in by hand. Add 5-10% compared with a site on the outskirts. For buildings in historic blocks without a lift, count another 3-5%.

7. Landscape and heritage constraints. Riva del Garda, Arco, Limone and part of Torbole have areas under landscape protection of the Autonomous Province of Trento. That means longer permits (landscape authorisation, the heritage authority's opinion for listed buildings), restrictions on façades, colours and window frames. Count 4-8 weeks of additional paperwork and a few forced material choices.

8. Quality of the initial design. A well-made project — with 3D renders, bill of quantities, material selection completed before the site starts — costs more upfront but saves 10-20% on the total, because it eliminates mid-works variations. In a B&B the advantage is double: the approved renders become the first photos for the listing, useful for the pre-launch of the season.

3 real scenarios on Lake Garda

Numbers speak louder than abstract examples. Three cases that represent most of the B&B projects we see in the area.

Scenario 1 — 3-room B&B in an 1980s house, refresh with bathrooms

A family in Arco opening a B&B on the top two floors of their own home: 3 guest rooms, a shared breakfast area, a building that's sound but dated. Goal: get off to a good start without upheaving the building.

What we did: complete repainting, replacing the floors in the rooms (old strip flooring swapped for pre-finished oak), three bathrooms completely redone, a new breakfast area with a linear kitchen and counter, all light fittings replaced, blackout curtains, air conditioning in the rooms, USB sockets at the bedsides. Electrical systems updated at the critical points, no demolition of load-bearing walls.

Time: 8 weeks on site, 4 weeks of design and permits.

Final cost: €74,000 for roughly 110 m² across rooms and common area (≈ €670/m²), site supervision included. Room furniture (beds, bedside tables, textiles, seating) bought separately for another €12,000.

It's the "light" level in full: an excellent quality-to-investment ratio for starting out with three rooms that hold rates of €90-130 a night in high season.

Scenario 2 — 4-room B&B, full renovation with en-suite bathrooms

A 1970s building near Torbole, bought to turn into a 4-room B&B (the maximum allowed in the Province of Trento). At the outset: shared bathrooms, original systems, a layout to rethink. An Italian-German client, first experience in hospitality.

What we did: demolition of partitions to create an en-suite bathroom in each of the 4 rooms, redistribution of the spaces, complete systems redone (electrical, plumbing, heating with heat pump, mechanical ventilation), light oak floors, microcement in the bathrooms, soundproofing of the walls between rooms, a breakfast room with a light professional kitchen looking onto the garden, air conditioning in all the rooms, lighting designed for scenes, one room made accessible to the requirements of DM 236/89.

Time: 18 weeks on site, 6 weeks of design and permits. Start in October, handover in March before the season.

Final cost: €245,000 for roughly 160 m² (≈ €1,530/m²), including full design with 3D renders and site supervision. Loose furniture not included (another €28,000 for the four rooms and the breakfast area).

It's the level where most of our quotes end up for a B&B born serious: every room with its own bathroom, boutique quality, without reaching true luxury.

Scenario 3 — Converting a building in central Riva into a charming B&B

A historic building in the centre of Riva del Garda, under landscape protection, bought by new owners to create a charming 4-room B&B with a precise identity. The project included the change of use and the complete aesthetic direction.

What we did: change of use from residential to hospitality with all the paperwork, conservative restoration of the protected elements (ceilings, traditional wooden window frames required by the heritage authority), internal redistribution with 4 rooms and their respective en-suite bathrooms in stone and burnished brass, systems entirely redone, one accessible room, a breakfast-lounge with a bespoke counter, herringbone parquet, lighting on magnetic tracks, and the B&B's identity (name, palette, signage, a coordinated welcome set). Olga used some of the suppliers and materials she had personally tested in the two apartments she manages in Riva — not chosen from a catalogue.

Time: 30 weeks on site, 10 weeks of in-depth design with several rounds of 3D renders and the landscape-approval process. Start in September, handover the following summer.

Final cost: €420,000 for roughly 190 m² (≈ €2,210/m²), including site supervision, design, heritage restoration and identity. Furniture and final styling additional €45,000 for the turnkey level.

It's the reasonable premium level for a protected historic centre: the constraints raise the cost, but a charming B&B with an identity in a strong location stands out on Booking and holds rates well above the lake's average.

Timing — when to renovate a B&B on Lake Garda

As with every hospitality property on Lake Garda, the season rules. Most B&Bs operate from Easter to the end of October; the site is best kept within the October-February window, with handover before reopening. Unlike a hotel, a small B&B has more flexibility: it's often possible to work while keeping part of the property open, but the quality leap (and the consistency of the new photos) is better achieved with the property closed.

The real seasonality

March-May: peak saturation of the Trentino builders. Hard to start, higher prices, overlapping with German clients who want a summer handover.
June-August: sites running at full tilt, but few new openings. The ideal period to design: surveys, renders, material selection, permits.
September-October: the ideal period to start the works. Builders available, softer prices, handover possible for the following spring.
November-February: excellent for internal sites. In this window the local builders are looking for contracts: in our experience quotes come out on average 8-12% softer than in spring. External works (façades, roofs) stop during periods of frost.

The practical rule: to reopen renovated by Easter, design must start by the previous summer and the site by October. Whoever starts in February for the summer season finds themselves on site in August, with lost bookings. We detailed the same reasoning, extended to a larger property, in our guide to hotel renovation costs on Lake Garda.

Which professionals you need (and what they cost)

Renovating a B&B is not a job for a single building company: it involves at least 3-4 figures, and understanding who does what helps you read the quotes.

Professional	What they do	Typical cost
Interior designer / Architect	Design, 3D renders, B&B identity, material selection	8-15% of works value
Surveyor (geometra)	Building permits (CILA, SCIA), change of use, cadastral filing	€1,500-4,500 flat fee
Building company (general contractor)	Construction works, masonry, plaster, laying	Majority share of the quote
MEP contractors (electrical, plumbing, heating)	Complete systems for rooms and common areas	25-35% of total works
Site supervision	On-site quality control, progress payments, variations	3-6% of works value

On a B&B quote, interior design + site supervision typically accounts for 10-15% of the total, often included in the turnkey quote. Our role is the design, identity and aesthetic direction part: from concept to photorealistic renders for deciding before you spend, through to final styling. For the full model we use on hospitality and commercial projects see commercial interior design; for the residential and detail part, interior design. We also have a specific guide to how much an interior designer costs to understand how this item breaks down.

Beware the "all-inclusive with no design" model. When a company offers a low price by saying "you do the design yourself", the end result is almost always confused, decisions get made on site under pressure, and in a B&B — where every bathroom-layout mistake repeats across several rooms — the final total exceeds that of a coordinated project. A false saving.

How to save without losing quality

Eight strategies tested on our sites. All legal, all reasonable.

1. Schedule the site out of season. October-February on Lake Garda means quotes on average 8-12% below the spring average. Builders have headroom and want to keep their team busy.

2. Standardise the room bathrooms. This is the most powerful lever in a B&B. A repeatable bathroom layout, with the same sanitaryware and the same tiles in every room, cuts laying and supply costs by 15-20% compared with four all-different bathrooms. You add variety with textiles and lighting, not with the tile.

3. Decide everything before you start. The greatest real saving comes from the absence of mid-works variations. Approved 3D renders, a detailed bill of quantities and materials chosen before the first day on site cut 10-20% off the final cost.

4. Keep the drainage positions where possible. Moving bathrooms and the kitchen is the highest "invisible" cost. If the current floor plan is reasonable, place the en-suite bathrooms near the existing stacks.

5. A smart mix of finishes. Premium materials in the spots the guest photographs (bathroom, headboard, breakfast area), correct but inexpensive materials in the less visible spots (corridors, service rooms). Same visual result, 25-30% less.

6. Make the most of tax incentives. If the B&B is created within your home, most of the works fall under the 50% residential renovation bonus (see below). You need proper invoices and a traceable bank transfer — no cash.

7. Negotiate payment by progress stages (SAL). Never more than a 20-30% deposit. Payment by clear stages (end of demolition, end of systems, end of floors, handover) gives you control over quality without tying up money needlessly.

8. A single source of responsibility. When there is one company and the designer coordinates everything, the "not my fault" disputes vanish. An integrated turnkey model — which we discuss in our guide to turnkey renovation. We regularly see clients who coordinated five tradesmen themselves and paid 25% more than budgeted.

Incentives and bonuses 2026 on Lake Garda

The Italian tax system in 2026 keeps several incentives active that are useful for anyone renovating a B&B in Trentino, especially in the "B&B in your own home" model. A practical summary, always to be verified with an accountant.

50% Renovation Bonus. A 50% income-tax (IRPEF) deduction on ordinary and extraordinary renovation expenses, with a spending cap of €96,000 per residential unit, recovered over 10 annual instalments. It applies to building works, systems, window frames, sanitaryware. For a family B&B created within the home it's the main instrument. It requires a traceable bank transfer and proper invoices.

Ecobonus for energy efficiency. A variable deduction (50-65% depending on the work) for heat pumps, condensing boilers, external insulation, high-efficiency window frames. Relevant for the 1960s-70s buildings in the centre of Riva del Garda with poor energy performance.

Furniture Bonus. A 50% deduction on the purchase of furniture and high-energy-class appliances, up to €5,000, linked to a declared renovation project. Useful for the room furniture if the work is correctly framed.

Grants from the Autonomous Province of Trento. The PAT periodically publishes calls for tenders to upgrade the hospitality offering and to restore the building stock in protected historic centres. Deadlines and requirements change every year: it's worth asking an up-to-date local surveyor.

Important: the bonuses are tax deductions, not discounts. You pay the full amount and recover it over the years. For those without sufficient IRPEF capacity (e.g. foreign owners not resident for tax in Italy) the mechanism may not be usable: in those cases it's best to do the net sums, without counting the bonus. Beware too of the tax regime: hospitality activity can change the classification of some expenses compared with purely residential work.

FAQ

How much does it cost to renovate a 4-room B&B on Lake Garda?

It depends on the level. For a refresh with touched-up bathrooms you start from around €70,000-100,000. For a full renovation with an en-suite bathroom in every room, new systems and a breakfast room, the realistic range is €200,000-280,000 over 150-180 m². For converting a protected building in a historic centre, with change of use and identity, you easily exceed €400,000. The en-suite bathroom is the item that moves the total the most.

How much does it cost to create an en-suite bathroom?

Carving a new bathroom out of a room costs €6,000-11,000 each, between demolition, new drainage, waterproofing, tiles, wall-hung sanitaryware and taps. Standardising the layout across all the rooms is the best way to slash the cost: same drainage stack, same materials, faster laying.

Does a B&B need to have accessible rooms for people with disabilities?

Yes, but for B&Bs the rule is lighter than for hotels. Under DM 236/89, for a bed and breakfast one accessible room is sufficient for people with disabilities (whereas a hotel requires at least two for every 40 rooms). The accessible room must guarantee a turning space of at least 150 cm in diameter for the wheelchair and an adequate bathroom, and it's preferable to place it on the lower floors. At the design stage you identify straight away which room to dedicate.

Do you need the fire-safety permit (SCIA) for a B&B?

Almost never, and it's an important difference from a hotel. The fire-safety SCIA obligation kicks in for hospitality properties with more than 25 beds (activity 66 of DPR 151/2011). A B&B in the Province of Trento is limited to 4 rooms and 8 beds, so it stays well below the threshold: no heavy fire-safety project. Basic safety measures remain mandatory all the same — gas and carbon-monoxide detectors in spaces with boilers or gas hobs, and compliant fire extinguishers.

What is the CIN and do I need it for the B&B?

The CIN (National Identification Code) has been mandatory since 2026 for all hospitality properties and tourist accommodation, B&Bs included. It's requested through the National Database of Hospitality Properties (BDSR) of the Ministry of Tourism, with SPID or CIE, and must be displayed and stated in listings. Without a CIN you risk significant administrative penalties. It's not a site cost, but it's a step to put on the agenda before opening.

What are the requirements to open a B&B in the Province of Trento?

In the Autonomous Province of Trento, a B&B is the hospitality offered with family organisation in part of the building where you reside, up to a maximum of 4 rooms and 8 beds. The rooms must have a minimum floor area (indicatively 8 m² for one bed, 12 m² for two, with increments for each additional bed), and the property must stay open at least 60 days a year. These are details that affect the design: the minimum areas and the bathroom per room must be planned from the layout stage.

Do I pay VAT at 10% or 22%?

Renovations are generally subject to the reduced 10% VAT on labour and materials supplied by the company, not the standard 22%. For a B&B created in a home the residential relief applies in most cases; when business activity comes into play, some items may change rate. Always check with the accountant and make sure the quote clearly states the rate applied.

Can I renovate the B&B while staying open?

On a small B&B sometimes yes, working in phases and isolating the rooms on site. But it costs more, lengthens the timeline and risks negative reviews for noise and disruption. On Lake Garda the most sensible choice is to concentrate the works in the winter window October-February, with the property closed, and reopen with new photos before the season.

Conclusion and next steps

Renovating a B&B on Lake Garda in 2026 is a predictable investment if you know where the costs look: the number of en-suite bathrooms, the state of the building, any change of use, and the quality of the project. The good news is that a family-run B&B stays below the heavy regulatory thresholds of a hotel — no fire-safety for over 25 beds, just one accessible room — and so it costs less for the same perceived quality. A good project saves you 15-25% on the final total, even paying a fair price for the initial design, and gives you the first photos for the listing.

If you're considering opening or renovating a B&B in Riva del Garda, Arco, Torbole or elsewhere on the lake, the first step is a survey. In an hour we understand the state of the property, identify the critical points (systems, bathrooms to create, constraints, change of use), discuss budget, timing and the property's identity, and give you a realistic quote range with ± 15% accuracy already at the first meeting.

We work on three complementary fronts:

Commercial interior design — concept, property identity, 3D renders, specification and coordination for hospitality spaces.
Interior design — detailed design of the rooms and spaces, material selection, bill of quantities.
Coordinated renovation in turnkey mode, with a selected building company and single site supervision.

We work in Italian, English, German and Russian, manage sites remotely for owners abroad, and personally follow every project in Riva del Garda, Arco, Torbole, Limone and the rest of Trentino through to the handover of the keys.
