Turnkey Renovation: Complete 2026 Guide to Costs, Process & Contracts

"I want a turnkey renovation." It is a common request and the meaning is simple: I don't want to deal with anything. I want to leave the property empty, come back a few months later, and find it finished. The promise is attractive — and, done well, turnkey can be an efficient and less stressful way to renovate than DIY coordination.

But "turnkey" is a commercial term every contractor interprets differently. Behind the same word hide services ranging from "design + works + final cleaning" to "only construction, you handle the rest." The final bill difference can reach 30-40% of the budget.

This guide is for anyone considering a turnkey renovation in 2026. We cover what turnkey really means, cost per square metre, realistic timelines, how to read a contract, what guarantees to demand, and how to tell a serious contractor from an offer that's too good to be true. The figures are presented as market references for Lake Garda and northern Italy.

What "Turnkey" Really Means

Literally: the contractor hands you keys to a property ready to live in. In practice, there are three levels of turnkey, and knowing which one you're buying is the first thing to clarify.

Level 1 — "Structural" turnkey

Includes only construction work: demolition, masonry, services (electrical, plumbing, HVAC), screeds, floors, wall finishes, paint, interior doors. Excludes: furniture, curtains, decorative lighting, accessories, final styling. On handover you get a home that's structurally complete but empty.

When to choose it: you already know how to furnish, have a defined style, want to manage furniture selection personally.

Level 2 — "Complete" turnkey

Includes Level 1 plus all fixed elements: installed kitchen, finished bathrooms with chosen sanitary ware and fittings, main ceiling lights, wardrobes, custom built-ins. On handover the home is "liveable": only moving in tables, chairs, sofa, beds, and personal items remains.

When to choose it: you want to minimise decisions but already own significant furniture (sofa, table, beds) to bring into the new home.

Level 3 — "Design" turnkey

Includes Level 2 plus all furniture and objects: sofas, beds, tables, chairs, textiles, rugs, decorative lighting, artwork, plants. On handover you put the key in the lock, walk in, and the home is complete down to the last detail. This is the level chosen by international buyers of second homes around Lake Garda who don't want to deal with anything, by investors prepping a rental-ready Airbnb, and by those who simply prefer to delegate.

When to choose it: first home, second home, vacation property, rental property; you don't want to make decisions during construction; you want the guarantee that final visual result matches an approved design before work starts.

Our suggestion: when requesting a quote, have it written which of the three levels is offered, line by line. The worst surprises come from ambiguity here.

Who Actually Delivers Turnkey Renovations

Three supplier models exist on the Italian 2026 market.

1. Traditional construction contractor

A foreman, a crew, a few trusted suppliers. Handles construction, subcontracts trades, buys materials from local wholesalers. Pros: competitive prices, local knowledge, flexibility. Cons: design isn't included (you must bring it), material selection often limited, aesthetic outcome depends on your on-site decisions.

Ideal for: those who already have a complete interior design project and seek only execution.

2. Branded renovation company

National commercial entities with showrooms, sales consultants, standardised processes, closed price lists. They offer pre-packaged tiers ("Classic", "Premium", "Exclusive") at per-m² pricing. Pros: budget predictability, contractual deadlines, formal guarantees. Cons: limited customisation, materials often from corporate catalogue, high margins (you're paying for the showroom, advertising, commercial structure).

Ideal for: maximum simplicity, no strong aesthetic requirements.

3. Collaboration between an interior designer, contractor and licensed professionals

The interior designer develops the concept, layout, materials, furniture and visible details. The contractor executes the works; the appointed surveyor, architect or engineer verifies technical feasibility, prepares and signs permit and technical documents, performs statutory site supervision where required and carries the legally reserved responsibilities. The benefit is a tailored, documented design; the essential condition is that appointments, contracts and responsibilities remain clear and separate.

Ideal for: unique homes with design value, not "standard interiors"; owners who can't be on site daily; those with a clear style but without technical expertise to enforce it.

Turnkey Renovation Cost per m² in 2026

The question everyone asks. Honest answer: it depends on many factors, but we can give reliable 2026 market ranges. Figures below refer to the contractor's cost, including construction, services, materials, and fixed elements (Level 2 turnkey), for a typical residential apartment in northern Italy.

Type of intervention	Cost per m² (2026)	Includes
Light renovation	€600 — €900/m²	Paint, floor replacement, refreshed bathroom, new kitchen, services retained
Medium renovation	€900 — €1,400/m²	Bathroom and kitchen redo, partial services, new floors, complete paint
Complete renovation	€1,400 — €2,000/m²	Internal demolition, space redistribution, new services, mid-level finishes
Premium renovation	€2,000 — €3,500/m²	Premium materials, custom furniture, home automation, deep design
Luxury renovation	€3,500+/m²	Marbles, rare veneers, bespoke craftsmanship, integrated automation

Practical example: an 80 m² apartment in Riva del Garda, "complete" level with medium-high finishes and custom kitchen, typically sits between €120,000 and €160,000 turnkey (Level 2). With Level 3 (furniture included), add 20-40%: total €150,000-€220,000.

International benchmarks (Level 2 complete renovation)

Country	Per m² (2026)	Notes
Italy (Lake Garda / Trentino)	€1,400-€2,000	Our market — strong artisan network
Italy (Milan)	€1,700-€2,500	+20-30% urban premium
Germany	€2,000-€3,000	Higher labour costs
UK (London)	£2,500-£4,500	Premium market
USA (metro areas)	$300-$550/sq ft	Varies hugely by state
Switzerland	CHF 3,000-4,500	Premium across the board

What drives the price

Starting condition of the property, complexity of redistribution, finish quality level, size (larger m² cost less per m² due to labour scaling), geographic zone, urgency, and tax incentives (Italy has various renovation bonuses recovering 50-65% of qualifying spend — a serious contractor helps you prepare the paperwork).

Realistic Timelines: What to Actually Expect

The second myth to dismantle is about timelines. "Turnkey in 2 months" is a promise almost no one keeps. The real timelines:

Phase 1 — Design (3-8 weeks)

Site visit and survey, interior design, material selection and 3D renders; separately, the licensed professional prepares the required technical documents, permits and bill of quantities. This phase reduces late decisions and variations during the works. See why every renovation project needs 3D renders.

Phase 2 — Permits and paperwork (2-6 weeks)

Varies by municipality. In Italy, CILA or SCIA filings; in Germany, Baugenehmigung if structural. Lake Garda area and Trentino are generally faster than Milan or Rome.

Phase 3 — Construction (8-20 weeks)

The core of the work. For an 80 m² apartment with complete renovation, count 10-14 weeks of active construction under normal conditions. Premium or luxury: 14-20 weeks.

Typical breakdown:

Weeks 1-2: demolition, service routing
Weeks 3-4: electrical, plumbing, HVAC
Weeks 5-6: screeds, enclosures, first walls
Weeks 7-9: tiles, plaster, stucco
Weeks 10-12: floors, interior doors, paint
Weeks 13-14: kitchen/bathroom installation, fixed elements, final cleaning

Phase 4 — Handover (1 week)

Final walk-through, punch list, document and warranty delivery, training on systems (automation, boiler, ventilation).

Realistic total for an 80 m² complete renovation: 4-6 months from contract signing to key handover.

Anyone promising less at quote stage is either selling something different or has hidden error margins that will surface during the build.

The Contract: 7 Clauses to Demand

A serious turnkey contract explicitly contains:

Clear scope: what's included and excluded, line by line, with quantities and material grades. Not "mid-grade tiles" — "Porcelain tile 60×60, brand X model Y, price €45/m²."
Milestone schedule: not just final handover date, but intermediate targets.
Late penalties: percentage per week of unjustified delay (typically 0.5-1% of contract per week).
Payment terms: staged against progress, never more than 30% upfront. High upfront requests are a risk signal.
Variation handling: how mid-build changes are priced (reference price list must exist, not "we'll negotiate later").
Warranties: 2 years on finishes, 10 years on structural works (legal minimum in Italy), supplier warranties transferred (appliances, boiler, etc.).
Site insurance: contractor's liability policy active for the full project, minimum €500,000 coverage for third-party and neighbour damage.

The decisive test: ask for the contract PDF before signing day. If the contractor gives it only at signing "to read together," something they don't want you to study calmly exists.

How to Pick the Right Contractor

70% of job-site disasters come from picking the wrong contractor, not from the project. Signals to watch:

Positive signals

Verifiable portfolio with references: real clients you can call and visit their finished projects
Physical local presence: office, warehouse, owned vehicles — not a virtual address
Stable corporate structure: VAT registration 5+ years, tax compliance current, accessible financials
Employed staff, not total subcontracting: a contractor who subs everything doesn't control quality and inflates the chain
Active insurance policies: shown without drama
Professionalism in the quote: detailed document, not "estimate on a sheet"

Red flags

Quote significantly below market (30%+ under range): either an error or will be made up with "variations" during construction
Large upfront deposits before starting
Cash-only, "no invoice": illegal (no tax deduction) and leaves you without protection
Unrealistic timelines: "we finish a 100 m² renovation in 6 weeks." No, you won't.
Pressure to sign immediately: "sign today or the price goes up." Serious contractors don't behave this way.
No verifiable references: "we're discreet, we can't share other clients' contacts." Happy clients happily speak.

Managing Renovation as an International Owner

A common situation involves international owners who buy a second home around Lake Garda or in Trentino and cannot be on site daily. In these cases, contracts and responsibilities between the contractor, licensed professionals and designer need to be clearly defined.

What works:

Distinct, coordinated contacts: the interior designer for aesthetic decisions, and the licensed professional and site foreman for technical and execution matters
Weekly video updates with photo reports
Decisions locked before construction starts (via approved 3D renders), not mid-build
International bank transfer payments with proper invoicing for tax deductibility
Remote access to construction cameras for spot checks
Final handover in person or with notarised delegation

The service is available in Italian, English, German, and Russian — the language choice affects comfort, not service quality.

For a concrete example, the Ardaro holiday-home project in Riva del Garda documents the existing condition, agreed plans, remote design approvals and finished interior while keeping the designer's role separate from the responsibilities of the appointed technical professionals.

FAQ

What's the real advantage of turnkey vs self-managing?

Stress reduction and final budget control. Self-managers save the contractor margin (10-20%) but spend double the time, make pressured on-site decisions, pay costly variations and coordination errors. The final bill is often similar or higher than a well-done turnkey.

Can I change my mind during construction?

Yes, but every change costs. If the project was properly done with 3D renders, the temptation to change fades. Mid-build changes range from +5% to +40% on original cost depending on phase.

Are Italian tax bonuses included in turnkey cost?

No — bonuses are a tax deduction you recover with your tax return (typically over 10 years). Turnkey cost is what you pay gross of the bonus. The contractor prepares paperwork; you (or your accountant) use it.

Does turnkey work for an Airbnb?

Yes — and it's ideal for investors. Complete handover = immediate bookings = ROI from month one. Level 3 (with furniture and full styling) is practically mandatory: "half-finished" Airbnbs don't perform. We have a dedicated guide: Airbnb interior design on Lake Garda.

What's the difference between turnkey and general contractor?

A general contractor coordinates construction and subcontracts but typically excludes interior design and furniture. Turnkey is broader and can include general contracting + design + furniture.

How much does design within turnkey cost?

Interior design fees are normally a separate budget item. Before signing, verify whether the offer covers execution only, also includes interior design, or includes separately appointed technical services from licensed professionals.

Can I do turnkey with Italian 50% renovation bonus?

Absolutely. The turnkey contractor issues invoices that form the basis of the tax deduction. Turnkey is actually the cleanest model from a documentation perspective.

How to Request a Turnkey Quote

The first step is a conversation. An interior-design site visit can clarify aesthetic potential, priorities and realistic budget and timeline expectations; technical feasibility remains for the appointed licensed professionals to verify.

After the visit we prepare:

A project concept with possible aesthetic directions
A preliminary budget range
A realistic timeline with main phases
A proposed level of interior design and aesthetic assistance suited to your case

If you decide to proceed, the next step is complete interior design documentation and a detailed line-by-line quote; any reserved technical services remain with the appointed licensed professionals. No surprises, no excessive upfront payments, no pressure.
