How it works.

6 stages to get your Asumma home in 1 year. 

1. Custom concept

4 to 6 weeks
€4,500 + VAT (fixed price)

In Stage 1, we learn about your vision, needs, and interests for your new home. We investigate the soil and analyze your plot of land, in order to deliver a custom architectural concept for your home. The length of this stage is impacted by the local soil investigator’s availability.

See all deliverables for Stage 1.
  • You choose your Asumma house model and select your desired house configurations.

  • We review your plot’s building rights.

  • We visit and analyze your plot of land.

  • We order the soil investigation of your plot via our local partners. (Locations that are difficult to access or with challenging site conditions can increase the price somewhat at this stage.)

  • We adapt a bioclimatic strategy for your house and plot.

  • We design a Stage 1 architectural concept to meet your needs and the conditions of your site.

2. Design draft

Up to 6 weeks
€4,500 + VAT (fixed price)

In Stage 2, we adapt the architectural sketches for your house, based on your feedback. After we align on a final design, we begin selecting materials and recommend your construction consultant, in order to get estimates for the cost of your new home.

  • We adapt our Stage 1 architectural concept based on your feedback.

  • We present you with a Stage 2 design draft, customized to suit your needs and your plot.

3. Permitting

2 to 3 months
From €80 per square meter

In Stage 3, Asumma submits your complete house proposal to the local building authorities, including all drawings and documents. This entails semi-detailed architecture and essential engineering. The processing speed of your municipal building authority impacts the total time required for this stage, especially if there are long queues.

  • We generate semi-detailed, building-authority level architecture and structural engineering drawings.

  • We secure an HVAC engineering energy certificate and supporting HVAC drawings. 

  • We engage with and ultimately submit all drawings and required documents to your local building authorities, who will grant you a building permit for your new home.

  • If the authorities require amendments to your application, we manage the appeal.

4. Construction design

2 to 3 months
€4,500 + VAT (fixed price)

In Stage 4, we produce the highly detailed architectural drawings required to manufacture and assemble your home — including full structural, electrical, HVAC, and CLT element engineering. Our partner suppliers and contractors will provide binding offers for the cost of the materials to build your home.

  • We produce high-fidelity architectural drawings, enabling our partner factories to manufacture and assemble your home, and supplier partners to fulfill precise orders for your new home.

5. Construction oversight

4 to 6 months
From €50 per square meter

Our supplier partners manufacture and deliver your house elements to your plot. Once there, our contractor partners assemble and install your house on your plot.

  • We oversee that our partner suppliers deliver all the house elements to your plot of land, where our vetted contractors assemble and install your home, including all finishings — such as utilities connections, installation of appliances, and interior finalization to ensure a move-in ready home.

6. Inspection

4 to 6 weeks
From €25 per square meter

In Stage 6, we commission a complete final inspection of your home, ensuring the above-grade construction of your house. Once your house is fully inspected and approved for move-in, we deliver your new key-in-hand. Congratulations. Your new home awaits.

About our prices

Asumma Homes

How can I figure out the true cost of building a new house? 

You might find that you have trouble getting an exact answer when researching pricing for buying and building your own house. Upfront, many companies will only provide you with a list of the cost of the materials for a new house. However, a cost breakdown of materials is only a partial picture of the final price. Building a new home requires architectural and engineering customizations for your plot of land, a permit from your local building authorities, construction-level architecture and engineering, land preparation, securing materials producers, contracting construction partners to build your house, as well as commissioning of a final inspection, among other steps.

What is the average cost to build an Asumma house? 

On average, based on current market data cost breakdowns, you can estimate to pay €2,700 - €3,200 per square meter for a high-quality Asumma home, excluding the cost of land. This pricing band accounts for customizations for your new home. For instance, sustainability customizations that enable carbon-negative house operations require more upfront cost — but the long-term energy savings from their implementation more than recover these costs for you. Other customizations, such as house layout modifications, also incur additional cost. Other factors can impact cost, such as the soil investigation of your plot — with difficult to access plots and soil types impacting cost, among other factors. That said, you can estimate that building a new 100m2 home starts at €270,000, excluding the cost of your plot of land. With our partners, your home is built to a 'house-ready delivery' stage, as defined by The Finnish Association for Manufacturers of Prefabricated Houses. A 'house-ready delivery' accounts for 90% to 95% of the cost and work for your final house.

If building a new house has such a reasonable price tag, then why do so many people buy existing homes?

Although building a new house has quite a reasonable price tag, most people still buy existing homes, rather than building their own. Why? One reason is education. The idea of building seems daunting and inaccessible to many, although it doesn’t have to be that way. People might fear that costs will creep up, that one has to become an expert in building a house to figure out the process, that it will eat up an enormous amount of time, and that there are unforeseen risks. In some ways, this is true: building a house is complicated, especially for people who do not work in the construction industry. That said, at Asumma we aim to make the process simple for you.

So, what does Asumma do differently?

We operate as your personal concierge across the entire house-building process. We oversee all the immaterial aspects of building your house — from architecture and engineering, to project management. We work with a network of partners who supply materials and construct your house. We also provide fixed, upfront pricing for a defined scope of work, on a stage-by-stage basis, with clear stages. From the outset of our work for you, we engage our partners to get a cost breakdown for manufacturing and building your house — giving you an upfront estimated total cost for your new Asumma home. We believe this level of clarity and fidelity will help you make an informed choice.

Anything else that I should know? 

Market fluctuations will impact the cost of certain materials, such as steel or timber. But these fluctuations are relative, considering the full life-cycle of a home. While markets can impact the quotes offered from our partner factories and suppliers, keep in mind that we have preferred status with many suppliers, helping ensure that you get a house built from high-quality materials.

Your new home awaits.
