Two story steel houses from 143 to 256 m², built in our factory in Turkey and shipped worldwide. Every model uses the same galvanised light steel frame, 140 mm exterior walls and A1-class rock wool insulation as our single story steel houses, with a steel-chassis intermediate floor between the levels. Browse the 10 models below, from €54,900; listed prices exclude VAT.
Two Story Steel Houses by Idealmod
This range brings together 10 two story steel houses, from the 143 m² model to the 256 m² family home. Every house is built with the same galvanised light steel frame and wall build-up as our single story steel houses, with a steel-chassis intermediate floor and a steel-frame staircase. The construction quality does not change when you add a second floor. What changes from one model to the next is the floor area, the number of bedrooms and how the rooms are split between the two levels.
In most two-storey plans, the ground floor holds the living room, kitchen and often a guest room, while the main bedrooms are upstairs. This keeps daytime and night-time spaces apart and gives you more floor area on a smaller plot. The frame, profiles, intermediate floor, staircase, roof and fittings are made in our factory in Gebze, Kocaeli, then shipped to your site and assembled on a concrete slab that you prepare in advance.
Who These Two Story Steel Houses Suit
Our customers choose two story steel houses for permanent family homes, larger holiday villas and homes for extended families. They suit buyers who want the look and feel of a conventional two-storey house, with a plastered or fibre cement facade, a 280 cm wall height and a thick, rock-wool-insulated wall, but built far faster than masonry construction.
If you would rather keep every room on one level, see our single story steel houses, which start at 45 m². If budget is the main concern, our two-storey prefabricated houses offer the same number of floors at a lower price.
Choosing a Size and Layout
Most buyers start with the number of bedrooms they need and the size of their plot, then compare plans of a similar area. Each model page shows the floor plans and the window and door sizes, so you can check the room layout, daylight and furniture placement on both floors before you order.
Because the light steel frame is designed for each project, the plans can be adapted more easily than panel systems. Room sizes, window positions, the staircase position and the facade can be changed to suit your plot and your needs. Tell us what you would like to change when you request a quote.
Two-Storey Steel House Prices
Catalogue prices for our two story steel houses start at €54,900 for the 143 m² model and go up to €93,100, excluding VAT. Most models fall between roughly €360 and €390 per square metre. A two-storey house costs more than a single-storey one of the same area because it also needs an intermediate floor, a staircase and a frame designed to carry the upper level.
The price of each model is shown on its product card above. The catalogue price covers the building itself. Shipping and the work on your plot are not included, so your total budget depends on where the house is going and what is needed on site.
| Model size | Catalogue price (excl. VAT) |
|---|---|
| 143 m² | €54,900 |
| 156 m² | €59,600 |
| 193 m² | €72,600 |
| 204 m² | €74,500 |
| 245 m² | €89,400 |
What the Price Includes
The catalogue price covers the complete building shell on both floors, the intermediate floor, the staircase, the openings and the fitted services.
- Galvanised light steel frame and all profiles.
- Intermediate floor and staircase.
- Exterior and interior cladding in your chosen option.
- Rock wool wall insulation and mineral wool roof insulation.
- Exterior and interior doors.
- Roof.
- Windows.
- Interior and exterior paint materials.
- Electrical installation, sockets, light fittings and the indoor fuse box (consumer unit).

What Is Not Included
We list the exclusions in full so you can budget accurately before asking for a quote.
- Building permit.
- Concrete slab, excavation and screed.
- Floor covering, parquet and tiling.
- Kitchen units and sanitaryware.
- Heating and cooling installations.
- Shipping.
- Any lifting equipment needed on site.
- Application labour for painting, mastic and silicone.

The concrete slab must be ready before the house arrives, so it is worth getting a local quote for it early. Once your contract is signed, we provide the slab drawings and the project plans your contractor needs.
What Affects the Final Cost
Your final cost depends on the model you choose, the cladding and roof options, how far the house travels and the work needed on your plot. Shipping cost depends on the distance, the method and the number of trucks the model needs. On site, the slab, screed, floor finishes, kitchen and bathroom fittings are priced locally. Changes to the standard plan, local taxes and permit fees also add to the total.
Send us your location and the model you are interested in, and we will prepare a quote that shows the house price, your cladding and roof choices, and the items you need to arrange separately.
How Our Two Story Steel Houses Are Built
Every model in this range uses the same light steel system as our single story steel houses, with an added intermediate floor and staircase. The frame is made from cold-formed galvanised steel profiles that are cut and prepared in our factory, then assembled on site with mechanical fixings.
A Galvanised Light Steel Frame
The load-bearing structure is a light steel frame made from galvanised, cold-formed profiles, and it carries both floors and the roof. Exterior walls are built on a 140 mm steel frame and interior walls on a 90 mm frame, with a wall height of 280 cm on each floor. Galvanising protects the steel against corrosion.
Intermediate Floor and Staircase
The upper floor sits on a steel chassis covered with 16 mm Betopan or fibre cement boards. The staircase has a steel frame with 16 mm Betopan or fibre cement treads. Both are made in the factory together with the rest of the house.
Wall Build-Up and Cladding Options
The cavity inside the steel frame is filled with A1-class, non-combustible rock wool, which provides thermal and acoustic insulation on both floors. On the outside, a Tyvek breathable membrane is fitted behind the cladding. You can choose between two exterior finishes:
- Boardex with a mineral plaster finish, for a smooth, rendered look.
- OSB with a fibre cement board finish.
Inside, the walls are finished with two layers of plasterboard, or OSB with plasterboard where you want a stronger fixing surface for shelves and cabinets.
Roof, Windows and Doors
The roof is insulated with 10 cm of A1-class mineral wool. You can choose a polyurethane-insulated roof panel, or OSB with a Tyvek membrane and trapezoidal sheet metal. Windows are 70 mm double-glazed PVC with double-opening sashes. The entrance door is steel, and interior doors are melamine doors.
Electrical and Plumbing
Electrical wiring and plumbing are installed inside the walls on both floors and handed over tested and working. Sockets, light fittings and the indoor fuse box are part of the package. You arrange the main grid connection panel and the utility meter with your local supplier.
From Factory to Move-In: Shipping and Installation
Buying a two-storey steel house from us involves four stages: production in our factory, shipping, preparing the foundation on your plot and assembling the house on site. Production and slab preparation can run at the same time, which shortens the overall schedule. Our guide on buying a prefab house from abroad sets out every step for customers outside Turkey.
Production and Planning
Once you confirm the plans, cladding and colours, the house goes into production. Production time depends on the model and the factory schedule, and we confirm the date in your contract so you can book transport and the slab work around it.
Shipping Worldwide
We deliver on a factory delivery basis. We handle customs clearance in Turkey and prepare the export documents, such as the ATR or EUR.1 certificate, the export declaration and the certificate of origin, and you arrange transport to your site and customs in your own country. Houses can travel by truck, ship or rail.
Foundation and Site Preparation
Every house needs a level concrete slab, which you prepare before delivery. The slab, excavation and screed are not part of our price. We send you the slab drawings after the contract is signed, so a local contractor can build it to the right dimensions while your house is in production.
How Long Installation Takes
A two-storey steel house takes longer to install than a single-storey one, because the frame, intermediate floor and staircase go up in stages before the cladding, plaster and interior boards are applied. The expected installation time for your chosen model is confirmed in your quote, together with any lifting equipment needed on site.
For projects abroad, we send an experienced installation supervisor. You provide local helpers and the basic assembly tools, and cover the supervisor's daily fee, travel, accommodation and meals. Our installation supervisors already hold Schengen visas, which saves time for projects in Europe.

When a Two-Storey Steel House Is the Better Choice
A two-storey steel house suits buyers who want a home that looks like conventional construction, higher ceilings on both floors, a non-combustible rock wool wall and more freedom to change the layout and facade. A two-storey panel prefabricated house is the most economical way to get a complete two-storey home with fitted services.
Single-Storey or Two-Storey?
A two-storey house gives you more floor area on the same slab, which helps on a smaller plot and keeps the bedrooms separate from the living areas. A single-storey house is simpler to build, needs no staircase and keeps every room on one level, but it needs a larger footprint. Compare plans in our single story steel houses category.
Comfort, Safety and Lifespan
Every project is prepared according to regional requirements, including seismic calculations. A light steel frame is much lighter than a masonry or concrete building of the same size, which reduces the loads on the foundation. For questions about local wind, snow or seismic rules, ask us for the technical details of your chosen model.
Insulation for Hot and Cold Climates
The 140 mm exterior wall is filled with rock wool on both floors, and the roof has 10 cm of mineral wool, so the house keeps indoor temperatures stable in both hot and cold weather and reduces noise from outside. The Tyvek membrane behind the cladding keeps out wind and water while letting moisture escape from the wall.
Fire Safety
The rock wool in the walls and the mineral wool in the roof are A1-class, the highest reaction-to-fire class for building materials, meaning they are non-combustible.
Durability
Lifespan depends on the climate, the site and regular maintenance, such as repainting and keeping gutters clear. The frame and all metal parts exposed to the weather are galvanised to slow corrosion.
Building Permits and Local Rules
A building permit is not included in the price, and you need to obtain it from your local authority before installation. Rules differ from country to country and sometimes from one municipality to the next. Two-storey houses are more often affected by local limits on building height, plot coverage and appearance, so check these before you choose a plan.
In most places, the permit application requires architectural, structural, mechanical and electrical drawings prepared by a local architect or engineer. We can share the floor plans and technical specification of your chosen model to support that work. We cannot give legal advice on local regulations, so please consult your local authority directly.
