What is a modular home?

A modular house is a building made of ready-made elements (modules), prefabricated in a factory and assembled on the investor’s plot in just one day. This technology eliminates typical problems of traditional construction, such as weather delays, execution errors, and lack of budget control.

Single-story modular house – modern construction technology tailored to your needs

A single-story house built using prefabrication technology is an ideal solution for those who value functionality, flexibility, and quick completion time. Thanks to advanced construction technology, you can move into your own home in a few weeks, gaining comfort and the possibility of easy expansion in the future.

How much does a modular house cost in 2026? – specific numbers and examples

Prices of modular houses mainly depend on the area (m²), finishing standard, construction type, and additional options. Below we present a realistic price list for 2025/2026, prepared based on the offer of PARTNER – a prefabricated house manufacturer with over 30 years of experience.

Table: Prices of Modular Houses in “Turnkey” and “Developer” Standard

The developer version does not include floors, interior doors, kitchen, and heating, among other things.
The “turnkey” version is a ready-to-move-in house – from kitchen to bathroom and lighting.

What affects the final costs of building a modular house?

1. House area (m²)

The larger the area, the more modules need to be prefabricated and transported. Example: a 70 m² house (e.g., BYK model) in the “turnkey” version costs 316,500 PLN net, while the price of a modular house over 100 m² can reach as much as 530,000 PLN.

2. Finishing standard: developer vs. turnkey

Choosing the “turnkey” version allows you to avoid additional expenses after assembly – you don’t need to look for a finishing crew. This solution is recommended for investors who want to move into a ready-made house without supervising finishing work.

3. Foundation cost

Not included in the price list. The cost of making a foundation slab depends on ground conditions, but it’s usually an expense of 25,000 – 40,000 PLN. PARTNER also offers foundation pricing after a site inspection.

4. Transport and assembly

Transport of the modular house and its assembly on site (using a crane) are included in the final cost estimate. The average cost for models up to 100 m² is about 12,000-18,000 PLN.

Advice from a PARTNER specialist

“It’s not worth saving at the design and technical finishing stage. A well-planned modular house is like building blocks – easy to expand in the future, but only if all installations are thought out at the factory production stage.”

The price of a modular house at Partner – transparent cost of the building and the entire investment

At Partner, we clearly separate the price of the modular house from the full investment cost. The house price includes the building itself in the chosen standard – from developer’s shell to turnkey. The full investment cost, however, includes all elements necessary for actual habitation: logistics, assembly, plot preparation, foundations, utility connections, and required formalities. This way, the client knows from the start what is included and what constitutes a separate stage of work.

This approach helps avoid underestimations and provides a reliable budget overview, instead of abbreviated price lists that do not show the full scope of the investment.

How does Partner build a full modular house cost estimate?

We prepare each quote in clear blocks, so that the client fully understands the cost structure:

1. The Building

Includes construction, partitions, joinery, insulation, and installations according to the chosen standard. In the turnkey variant, we also include complete interior finishing.

2. Transport and Assembly

We price delivery logistics, unloading, assembly organization, and all work performed on the plot: connections, sealing, and commissioning of installations within the agreed standard.

3. Plot and Infrastructure

Foundation with conduits, earthworks, site preparation, drainage, and utility connections or alternative solutions – all itemized as a separate, controllable scope.

4. Documentation and Formalities

Elements required for implementation and acceptance, tailored to the specific plot and formal situation.

This way, the client receives a cost estimate that can be realistically planned and phased, instead of approximate ranges.

Turnkey modular house at Partner – a standard with a defined scope

At Partner, a turnkey modular house always means a clearly defined scope of work and materials. The price depends on the finishing standard, not just the term itself. The client knows exactly what they receive inside the house and at what stage they can move in without organizing additional crews.

The price of the turnkey standard is influenced by, among others:

• completeness and quality of bathroom finishing,
• type of flooring and interior joinery,
• scope and number of installation points,
• level of detail finishing,
• heating and ventilation solutions used.

This means a turnkey house from Partner is a ready-to-move-in building, not a state requiring further investment.

Foundation, assembly, and logistics – elements we price fairly

A quote from Partner always takes into account the actual plot conditions. The foundation is not a single lump sum item, but a scope based on ground conditions, terrain configuration, and the technical requirements of the house. Similarly, assembly and transport – their cost depends on access, unloading space, and organizational possibilities on the plot.

This approach helps avoid additional charges resulting from underestimating local conditions and gives the client full control over the budget.

Real price of a modular house in Szczecin and West Pomerania

In the West Pomeranian Voivodeship region, the price of a modular house at Partner results from a combination of the building price and local costs. We take into account transport, assembly, ground conditions, and location specifics, including factors influencing external solutions. This ensures the quote is tailored to the realities of the investment location, not based on average rates.

Minimum budgets – how does Partner approach simple projects?

For projects with a limited budget, Partner clearly separates:

• the cost of the building in the simplest possible standard,
• plot costs necessary to erect the house,
• elements that can be completed in stages.

This division allows for reasonable investment planning, without disappointments and with full awareness of the scope.

Why do clients choose Partner’s quote?

Customers choose the Partner modular home offer because they receive:

• a cost estimate based on a real scope, not marketing slogans,
• a clear breakdown of building costs and plot works,
• a standard described with specifics, not generalities,
• the ability to plan the budget and phase the investment,
• a single Partner responsible for the consistency of the entire process.

If you are looking for a reliable quote for a modular house, one that reflects reality, not just looks good in an offer – at Partner, we start with specifics.

Where not to save when building a modular house?

1. Foundations

A cheap foundation can cost double later. Uneven settling of the slab risks cracks in walls and problems with module assembly.

2. Electrical and plumbing installations

Installations are prefabricated in the factory and enclosed in walls. Corrections after assembly are difficult and expensive – that’s why it’s worth ordering a complete installation with sockets, lighting, and connections.

3. Insulation and joinery

Choosing cheaper windows or weaker insulation is a momentary saving – but rising heating costs will quickly negate this difference. PARTNER offers triple-glazed PVC windows and insulation with wool or cellulose up to 300 mm thick.

4. Kitchen and bathroom

The developer version requires additional investments in furniture, appliances, fixtures, and tiles. Finishing one bathroom costs 20,000-30,000 PLN, and a kitchen 25,000-40,000 PLN.

What can you save on – without risk?

• Optional extras like air conditioning, blinds, terrace – can be purchased later.
• Photovoltaic panels – depend on the building’s energy characteristics, but are not always mandatory.
• Preparatory work on the plot – possible to do independently with investor experience.

Why is a modular house a good investment?

Fixed Price from Contract to Keys

Construction costs won’t increase during the process – regardless of changes in material prices. Example: the price of the MAMUT 1 model is exactly 290,000 PLN net – and that’s what you pay, nothing more.

Quick Construction (up to 89 Days)

The construction process takes place in controlled factory conditions, and assembly takes 1 day. You don’t waste time and money on endless supervision of construction crews.

Energy-efficient Standard

Thanks to thick insulation, modern installations, and prefabrication accuracy, modular houses are very energy efficient.

Expansion Possibility

Modular technology allows for easy addition of extra rooms. In the future, you can expand a 70 m² house to 100 m² without having to move.

Sample cost estimate: 70 m2 modular house (MAMUT 1)

After adding 8% VAT: 372,600 PLN gross

Summary – how much Does a Ready-Made Modular House Cost?

The price of a modular house in 2026 typically ranges from PLN 230,000 to 530,000 net, depending on the area and standard.
Including the cost of foundations and assembly, a full investment in a ready-made house of approx. 70 m² in the ‘turnkey’ version is about PLN 350,000–400,000 gross.

FAQ – Frequently Asked Questions

How much does it cost to build a modular house with an area of up to 70 m²?

Building a house with an area up to 70 m² usually costs from about 210,000 to 300,000 PLN net depending on the finishing standard and scope of work. The price list for ready-made prefabricated houses includes both developer and “turnkey” versions.

2. Do ready-made prefabricated houses require a building permit?

Yes, as with traditional houses, prefabricated houses also require a building permit, unless their built-up area does not exceed 35 m² and they meet specific notification conditions. For houses up to 70 m², often a notification of construction intent to the county office is sufficient.

Are houses made from prefabricated elements durable and safe?

Yes, houses made of ready-made elements are created in a factory with strict standards and quality control. Thanks to prefabrication, external and internal walls are perfectly matched, which eliminates errors typical for on-site construction.

How long does it take to build a prefabricated house?

Thanks to prefabrication, the entire process is much faster than traditional construction methods. Ready-made modules are assembled on-site within 1-2 days, and the entire house can be ready in 2-3 months from signing the contract.

Can prefabricated houses be easily transported or expanded?

Yes, many prefabricated houses can be transported or expanded with additional modules if needed, especially if they are assembled from ready-made segments. This flexibility allows adapting the building layout to the individual needs of the investor.

What building materials are used in prefabricated houses?

Modular houses most often use Scandinavian wood structures, wool or cellulose insulation, and wall finishes without the use of concrete or wet plasters. This allows for quick project completion in any season.

Can a prefabricated house have an attic and an area of over 100 m²?

Yes, the offer also includes houses with a usable attic and an area over 100 m². Despite the larger area, they are still assembled in a short time, and thanks to ready-made module technology – ready to move in in just a few weeks.

Will the cost of a modular house in 2026 be the same as in 2025?

Costs may change throughout the year, so it’s best to rely on an up-to-date quote for a specific standard and location.

Does the turnkey price for modular houses always include the foundation?

Not always. The foundation is often a separate item depending on the ground and the scope of work on the plot.

Why do two modular houses of similar area have different prices?

Most often, the finishing standard, the number of wet zones, installations, and assembly and plot preparation costs determine it.

What most influences the cost of building a 70m² or 80m² modular house?

Turnkey scope, layout (compactness of the building mass), wet zones, installations, and plot costs.

Does ‘price per m²’ allow for good offer comparison?

Only partially. In modular houses, fixed costs (assembly, logistics, plot) are significant, which distort simple comparisons.

How to compare turnkey modular house prices between companies?

Based on an identical scope: materials, installations, bathroom, joinery, fittings, assembly, foundation, and investor-side elements.
