Warehouse – size selection, permits and price 2026

An unheated warehouse in Finland costs typically €300–700/m² in 2026, and a heated hall €700–1,800/m². Examples: a 200 m² unheated warehouse lands at about €100,000 and a 400 m² heated production hall at about €310,000. The biggest price drivers are insulation level, ground conditions and door specification.

Rent or build?

Rents for hall and warehouse space in 2026 run at €8–15/m²/month in Helsinki and Espoo, €4–10 in other large cities and €3–7 in smaller towns. Worked example: an unheated hall at €500/m² equals about 8.3 years of rent at €5/m²/month. Building on your own plot typically pays for itself in 7–12 years, and the residual value remains afterwards. High rent levels in growth areas shorten the payback, low levels lengthen it.

Renting wins when the space requirement is uncertain or short term: no capital tied up, full flexibility, and the landlord carries the major repairs. Building wins when the need is permanent and the plot already exists.

How are size and specification chosen?

The starting point is the use case: storage, production, machinery shelter or logistics. A growing model is the storage hotel, where a large hall is divided into lettable units – surplus square metres become an income stream. Timber element halls come in standard sizes from 100 to 1,000 m², so the sizing is not forced into a narrow mould.

Fix the insulation level early: a heated timber element hall has about 250 mm of insulation, a semi-heated one 175–200 mm, and an unheated one only a wind barrier board. Sectional doors have 40–82 mm panel thickness and U-values of 0.4–1.0 W/(m²K) – a heated hall takes the thicker panel. In northern Finland the snow load requirement raises the frame cost clearly compared with the south.

The frame solution also shows in the price: in an unheated hall a timber frame costs about €400–500/m², a steel-frame kit €450–550/m² and an arch hall €250–400/m². The arch hall is the fastest and cheapest weather cover, timber the typical choice for small and agricultural buildings. A heated hall is insulated with mineral wool or urethane – wool is cheaper, urethane more energy efficient.

Does a warehouse need a permit?

In practice always, because the 30 m² permit-free limit does not stretch to hall sizes. What is applied for is a building permit – since the start of 2025 the new Finnish term under the Building Act 751/2023. From the start of 2026 a processing guarantee applies: the municipality must decide within three months of a complete application, and for delays 20 % of the fee is refunded for each month started. Plans are submitted as a building information model or otherwise machine readable, so choose the designer early. The clock starts only from a complete application – gaps are the most common cause of delay. Attachments are usually the main drawings, proof of title to the site, an energy report, a moisture control plan, a ground survey and neighbour consultation. For farm machinery and produce stores it is worth checking the Finnish investment aid: a 25 % grant and an interest subsidy loan for 50 % of the cost.

Foundations are the hard core of the budget

The concrete slab costs €60–120/m² in normal storage use and €120–180/m² in heavy industrial use. Foundations and groundworks can be 30–60 % of the total budget, and more on difficult ground: a 1,000 m² hall on clay with piling can mean over €150,000 of groundworks. A ground survey before requesting quotes is the cheapest insurance in the whole project.

Element delivery cuts site time to weeks

A typical timber element delivery covers everything above the foundations: wall elements with windows and doors, roof trusses, gable triangles and roofing. About 70 % of halls are now erected by the supplier to a finished state, and the hall stands on average two weeks after erection starts. From order to finished hall takes 2–4 months. In a steel kit hall the frame erection takes about a week; delivery time for a standard model is about two weeks and for a bespoke one about three months. Winter construction works as long as the foundations were completed during the frost-free season.

Summary for the decision

• Calculate rent against building at your own location's rent level – payback is typically 7–12 years.
• Choose the insulation level by use: unheated €300–700/m², heated €700–1,800/m².
• Commission a ground survey before requesting quotes; foundations and groundworks can be 30–60 % of the budget.
• Allow three months for the permit process from a complete application.
• With element delivery the hall stands in about two weeks and is in use 2–4 months from order.

• Cold storage hall €300–700/m², warm storage hall €700–1,800/m² in 2026.
• Hall rents are 3–15 €/m²/month depending on the location – construction typically pays for itself in 7–12 years.
• In practice, a warehouse always requires a building permit; a 3-month schedule guarantee for processing from 2026 onwards.
• Concrete slab €60–180/m²; foundations and earthworks can be up to 30–60% of the total budget.
• The prefabricated hall is erected in approximately 2 weeks, with a total schedule of 2–4 months from the order.
• Around 70% of halls are currently delivered fully assembled by the supplier.
