About Nästlett
What is it?
Nästlett is an tiny house designed around three key features:
-
High Mobility
Easy to transport, connect, and remove.
Can be resold when no longer needed, ensuring a high return on investment.
-
Factory Line Production:
Fully produced in a controlled factory environment.
Lower production costs and consistent quality.
-
Best Quality/Price Balance:
A competitive product offering exceptional value on the market.
Why did we build a tiny house?
Hus i Bergslagen, a company specializing in prefab house production, received frequent inquiries about Attefallshus projects. Through our experience building these houses, we realized their compact size made them ideal for complete factory production.
When analyzing the market, we discovered that while a few manufacturers offered fully finished products, these often came with installation and removal challenges when no longer needed. This prompted us to develop a pilot project aimed at creating an Attefallshus with distinct advantages over competitors.
Why metal slab structure?
Maximizing interior height was a priority, which required a slab material other than wood. Due to its lower structural capacity compared to concrete or metal, wood would necessitate a significantly thicker slab.
After consulting with our structural engineer, we evaluated concrete and metal options:
-
Concrete: While strong, it posed two major challenges: excessive weight for a 30 m² slab and poor insulation properties.
-
Metal: Metal emerged as the ideal choice, offering both the strength required to support the house and superior insulation properties, particularly when paired with PUR insulation.
To optimize the metal slab, we addressed potential issues such as corrosion protection and mitigating thermal bridges caused by the material.
Disadvantages
-
Height Limitation:
Due to factory production and transport regulations, the total height of our Attefallshus cannot exceed 3.6 meters, even though Attefallshus regulations permit constructions up to 4 meters.
Despite our efficient slab design, which is only 20 cm thick, this results in an interior functional height that is approximately 30 cm shorter than the maximum allowed.
-
Limited Layout Options
To keep costs low and production efficient, we offer only one standardized layout. While customers can select from various colors and material options, changes to the slab dimensions, height, or internal dimensions are not available.

Attefallshus definition and regulations
What is an Attefallshus?
Building permits are typically required for new constructions, but Attefallshus are exempt from this requirement. A building permit is also not needed for extending an existing Attefallshus, provided that all the requirements for Attefallshus are met. However, in most cases, a notification is required for both new constructions and extensions.
What regulations need to be followed:
- There must be an existing single-family or two-family house on the property.
- It must be an accessory building or an accessory dwelling house.
- The maximum area may not exceed 30.0 m².
- The ridge height may not exceed 4.0 meters.
- It must be freestanding.
- It must be located in close proximity to the existing single-family or two-family house.
- It must be at least 4.5 meters away from the property boundary.
- It must be at least 30.0 meters away from railway tracks.
- It must not be built near buildings or in areas considered to have particular cultural or historical value.
- The detailed development plan for the area must not impose additional building permit requirements for Attefallshus.
- If it is an accessory dwelling house, it must not be located within or near areas of national interest for total defense.
