Building a detached house is the quintessential private project, and the question that opens it is always the same: how much per square metre? The honest answer is a band, not a number: in 2026, from EUR 1,300 to 2,500 per m2 turnkey depending on level, with the bulk of the current-quality market between 1,600 and 2,000. This article breaks the band down into concrete choices: what each level buys, where every euro goes and how to move from cost per m2 to the operation's real budget.

Bands by finish level

Level Cost per m2 (turnkey) 120 m2 house What characterises the level
Budget EUR 1,300 - 1,600 EUR 156,000 - 192,000 Standard finishes, standard services, code-level performance
Mid-range EUR 1,600 - 2,000 EUR 192,000 - 240,000 External insulation and performing windows, good finishes
High-end EUR 2,000 - 2,500 EUR 240,000 - 300,000 Home automation, advanced services, premium finishes
Above EUR 2,500 + EUR 300,000 + Bespoke architecture, special materials

Anyone also considering the shell (EUR 800-1,000 per m2) or the advanced shell (1,000-1,300) must know what they are comparing: these are intermediate stages, not alternatives; self-managed completion rarely beats turnkey on total cost, but it spreads the spending over time. And those aiming above current performance will find the extra cost of the passive standard analysed in the article on passive house costs.

Where every euro goes: the typical breakdown

For a mid-range house, the current breakdown of the construction cost. The shares vary little between comparable projects.

Block Typical share Content
Structure and building works 40 - 45% Excavation, foundations, walls, roof
Envelope 15 - 20% External insulation, windows, waterproofing
Services 20 - 25% Electrical, heating (heat pump), plumbing, MVHR, rough-ins
Finishes 20 - 25% Floors, tiling, bathrooms, painting

The table explains why downward negotiations always focus on finishes: it is the only genuinely compressible block that does not touch performance. Structure and envelope are sized by the codes, services by the energy design; finishes by taste and wallet.

The variables that move the estimate

Shape. A compact two-storey plan is the most efficient configuration: at equal floor area, a single-storey house with cantilevers, recesses and large glazing increases envelope and foundations and can cost 10-20 per cent more per m2.

Ground. Slopes, poor soils and high water tables are paid for in excavation, retaining walls and special foundations: from a few thousand euros to five-figure sums. Geology before buying the plot is the cheapest insurance of the whole project.

Location. Between the north and the south of the country the same works change price by double-digit percentages, as detailed in the article on north-south cost differences.

Timing. Price lists breathe with materials and energy prices: a quote has a validity date, and locking it contractually is worth as much as negotiating its amount.

Complete budget example: 120 m2 house, mid-range

Item Calculation Amount
Construction cost 120 m2 × EUR 1,800 EUR 216,000
Professional fees (design, supervision, permits, ~10%) EUR 21,600
Municipal fees and building contribution (estimate) EUR 12,000
Utility connections EUR 6,000
Contingencies (10%) EUR 21,600
Operation total excluding land EUR 277,200
Land (assumed 25% of the whole) ~EUR 92,000
Total with land ~EUR 369,000

Two readings. First: the real budget exceeds the area-times-rate product by 28 per cent before the land even enters; anyone planning financing on the construction cost alone discovers the rest mid-build. Second: the weight of the land (here 25 per cent) varies enormously with location, and it is the variable that decides where the project is viable.

Where to save without regret (and where not to)

Smart saving lives in three design choices: compactness of shape, standardisation of dimensions (out-of-standard windows and sanitaryware cost double at equal quality) and a hierarchy of finishes (concentrate the premium where you live and see, simplify elsewhere). The saving you pay for twice lives instead in the envelope and the services: every euro cut there becomes energy bills and discomfort for the following decades, and retrofitting will always cost more than doing it now. On which floor area and which items to compare quotes, the method reference is the article on how to calculate cost per m2.

Note: the figures shown are 2026 orders of magnitude for the Italian market, for guidance only. Every project requires a specific estimate based on a bill of quantities and up-to-date regional price books.

Frequently asked questions

As a 2026 order of magnitude: EUR 195,000-240,000 at budget level, EUR 240,000-300,000 at mid-range, above EUR 300,000 for high-end, always turnkey and always excluding land, professional fees, municipal fees and contingencies (which add 25-30 per cent).

For a house of current size, 10-16 months of actual site time from opening, plus the time for design and the building permit. Prefabs compress the site phase but not the permitting one.

Only with real site-management skills: self-coordinated completion saves the general contractor's margin but transfers coordination risk, overall warranty and contingencies to the client. For most clients, turnkey with a detailed specification remains the safer route.
