How much does it cost to build an attic house?
So, how much does it really cost to build an attic house? In 2023, an average turnkey detached house (which is delivered fully built and ready for use) of 25-30 square meters cost between SEK 800,000 and SEK 1,200,000. For an attefall house in the form of a building kit, the average cost varied from SEK 300,000 and up, depending on the supplier, material quality, craft costs and accessories.
Choosing a construction kit for an attic house means that you buy materials and instructions from a company and then either build it yourself or with the help of contractors. This option requires more personal effort in the construction process. Which means that you yourself have to project manage the entire process with craftsmen, documentation, documents, guarantees, costs and other things that are required in a complex construction process.
If you don't have knowledge and experience in the field, it usually won't be much cheaper with a kit. The reason is the time that must be spent and the external costs that are added to the entire project that are not included in the construction kit itself.

The price differences between different suppliers can be large. Some companies offer prices that are 200,000 to 300,000 kroner lower without compromising on the quality of materials or standard. Be sure to always review the delivery description and what is included in the price. If you find a reliable supplier, it can be a convenient and financially beneficial solution in the long run.

Remember that the costs here often rise quite a bit from the listed starting price, as it only covers part of the material. You either have to build it yourself, or hire different contractors. In addition, you need to take care of all documentation and all construction documents.

The other costs are relevant for both ready-to-turn attefall houses and attefall houses in the form of building kits. These costs include earthworks, installations and municipal fees, which are usually around SEK 200,000 to 300,000. Also, costs can add up if you don't thoroughly research and plan for the lot. Each site is unique and requires individual assessment and preparation before the construction process for a detached house can begin.

Payment and financing of the shelter house
Always start by contacting your bank, as they probably have the best solution for you.
Here are some financing options to consider:
Home loan: If you already own a property, you may consider extending your current home loan to cover the cost of the second home.
Personal loans or blank loans: These loans are unsecured and require no collateral. Keep in mind, however, that the interest rates can be higher compared to home loans.
Construction credit: A form of credit where the bank finances the construction project in stages, as various milestones are achieved during the construction process.
Government grants or loans: In some cases, there may be opportunities to apply for government grants or loans for construction or renovation projects. Check with local authorities or institutions for more information.
Crowdfunding or private investors: Depending on the nature of the project, you may consider seeking funding through crowdfunding platforms or private investors.
Leasing: In some cases, leasing the storage house can be an option. This can be a good solution if you need more flexible financing.
Remember to carefully consider which option best suits your unique project and financial situation.
