House Production & Project Management
About Us
Hus i Bergslagen AB specializes in producing prefabricated houses and offers efficient, sustainable, and flexible solutions tailored to each customer’s specific needs. Based in central Sweden, we combine technical expertise with a strong commitment to delivering long-lasting quality.
Unique Projects – No Catalogue Homes
We do not work with standard models or catalogue homes. Every project is unique and developed from the ground up in close collaboration with the client. Already at the quotation stage, we create a detailed 3D model and provide a precise and transparent cost estimate. This gives you, as a client, a clear understanding of the project’s scope and cost – right from the start.
Quality, Function, and Energy Efficiency
Our goal is to carry out every project with care and precision. We create homes that are:
-
Functional
-
Energy-efficient
-
Designed according to your preferences and lifestyle
-
More Prefabrication – Less On-Site Work
Today, over 70% of construction work is carried out on-site. Our ambition is to gradually reduce this share by integrating more prefabricated components into our factory production. This results in:
-
Shorter on-site construction times
-
Lower costs
-
More consistent and safer quality
-
Our Vision
We firmly believe that by shifting more of the construction process to the factory, we can:
-
Reduce the production cost per square meter
-
Increase efficiency
-
Deliver houses of the highest quality

Our Expertise in Construction
Over the years, we have been involved in a wide range of construction projects, allowing us to build the expertise, experience, and tools necessary to tackle diverse construction processes. Below, we elaborate on the various types of projects we can confidently undertake.
This is how the construction process goes:
Order process
How to buy a prefabricated house from us
Buying a prefabricated house is a major investment and requires clarity, accuracy and security at every step. At Hus i Bergslagen AB, we have developed a structured ordering process that ensures that you as a customer have full control from first contact to finished delivery.
1. Initial contact and needs analysis
2. Architectural drawings and 3D model
3. Quotation and specification
4. Review and adjustments
5. Order and agreement
6. Production and delivery schedule
7. Support during the project
The process begins when you contact us with your idea, plot or architectural drawings.
At the first meeting, we take the time to carefully listen to your needs, desires, and vision for the house you want to build. We review fundamental factors such as site conditions, intended building size, floor plan ideas, architectural style preferences, and any specific requirements for energy performance or sustainability.
We also provide advice on how transport logistics, accessibility to the construction site and local building regulations can affect the design and planning of the project.
The goal at this stage is to create a common understanding and lay a clear foundation for the next steps — from 3D modeling and quotation preparation to full-scale production.
If you have your own architectural drawings, we accept them in DWG or PDF format. In cases where you do not have ready-made drawings, we can help you develop a basic layout.
From these drawings, we build a detailed 3D model, which is the basis for all further planning. The model makes it possible to accurately calculate material consumption, production volumes and provide an accurate cost estimate.
Once the 3D model is complete, you will receive a quote that is 100% based on actual material quantities and working hours. No templates or uncertainties – the quote is completely transparent and includes:
-
Material specification for walls, ceilings, floors and details
-
Scope of delivery
-
Production and delivery time
-
Clear price breakdown
We will go through the quote, model and specification in detail together. Here you have the opportunity to ask questions, adjust the scope, select or remove elements before we move forward.
When you approve the quote, a formal order agreement is written. This becomes the basis for our delivery and ensures that all parties have a common understanding of what is to be built.
After a signed agreement, production begins. All parts are manufactured in our factory, packaged according to assembly order and marked with unique ID labels. You will receive a delivery plan that includes:
Delivery date
Logistics and unloading instructions
Assembly instructions in digital and printed format
We are available throughout the construction process for technical questions, support and any adjustments. You will always have contact with a dedicated project manager with us who knows your project in detail.
Production process
How we manufacture your prefabricated house
At Hus i Bergslagen AB, our production process is designed for maximum precision, efficiency and control. Every step is based on careful planning and digital modeling to ensure high quality and reliable assembly on site.
1. Final 3D model and component planning
2. Material preparation and precision cutting
3. Volume division and packaging
4. Labeling and documentation
5. Quality control
6. Transportation and delivery coordination
After the order agreement is signed, we complete the 3D model and begin detailed planning of all components.
Each part of the building – walls, floors and roofs – is divided into layers and individual components, such as joists, panels, insulation and board materials. All components are given a unique ID and linked directly to the model database.
Based on the final component list, materials are selected, cut and prepared in our factory.
The wooden elements are cut with high precision based on the 3D model, using modern and calibrated machines to ensure consistent quality.
All components are grouped into manageable volumes depending on the project's methodology:
For prefabricated elements, the volumes are adjusted according to applicable transport dimensions.
For detached wooden houses, the volumes are adjusted according to the capacity of the assembly team and the conditions of the construction site.
Each volume is packed layer by layer (e.g. facade panel, battens, windbreak, frame, insulation, vapor barrier, OSB, plaster), and all parts for a specific wall are packed together to facilitate assembly.
Each component is marked with a unique ID number that is linked to the 3D model.
This labeling system enables:
Traceability of each part
Organized packaging and delivery
Precise and error-free assembly on site
We also produce a complete set of waterproof assembly drawings and instructions for each element. These include:
Assembly order
Component placement
Connection types (nails, screws, fittings)
Mounting instructions (distance, edge dimensions)
Each document also contains a QR code that links to the 3D model for a clear visual overview.
Before delivery, each package and component is checked to ensure that:
All parts included
Cuts are precise
The marking is correct.
The packaging follows the planned assembly order.
This check minimizes the risk of errors and delays during installation.
Once everything is packaged and approved, the volumes are loaded and delivered according to the agreed schedule.
We are responsible for:
Transport logistics
Access instructions to construction site
Unloading order adapted to the construction sequence
Our goal is to make work on the construction site as smooth and efficient as possible.
On-site assembly
Step by step
When the prefabricated building components arrive at the construction site, our experienced assembly team takes over. The entire assembly is carefully planned to ensure a fast, precise and safe construction.
1: Unloading and sorting
2: Checking the foundation and preparations
3: Mounting the walls
4: Floor and intermediate floor
5: Roof installation
6: Quality assurance and adjustments
All components are delivered in a predetermined order based on the assembly plan. Each component is clearly marked with a unique ID that is linked to the 3D model and assembly instructions.
Upon arrival, the material is unloaded and sorted directly into the correct working order, which minimizes unnecessary handling and streamlines assembly.
Before installation begins, the foundation is carefully checked for flatness, dimensional accuracy and compliance with the project's tolerances.
All measurements are verified to ensure that the prefabricated elements fit exactly. This step is crucial for the construction to be correct and stable.
Exterior and interior walls are installed in the order specified in the drawings and load-bearing structural plans.
Thanks to factory-made precision and clear marking, each wall section fits exactly without the need for cutting or adjustment.
Fasteners, fittings and anchors are used according to instructions to achieve both strength and correct compliance with building codes.
If the house has several floors, joists are installed between the floors when the ground floor walls are erected.
These elements are also prefabricated and sorted in the correct order. Each floor is placed and anchored according to technical drawings, creating a stable platform for the next level.
The prefabricated roof trusses or roof modules are lifted into place using a crane or lifting device depending on the scope of the project.
Assembly is carried out according to the lifting and installation instructions provided. In case of uncertain weather, the roof is temporarily covered to protect the structure before the final roof covering is installed.
Throughout the assembly process, every step is documented and checked to ensure that everything is in accordance with drawings and specifications.
Any deviations are addressed immediately on site before moving on.
The goal is for the structure to not only be quick to build, but also to meet the highest standards in terms of safety, durability and precision.
Inspection
Step by step
Once construction is complete and all parts are assembled according to plan, the inspection phase begins. This stage is crucial to quality assurance of the entire project before final delivery to the customer.
1: Preliminary inspection of work performed
2: Quality control per component
3: Review with customer or project manager
4: Action list and adjustments
5: Final inspection and approval
Before the formal inspection, an internal pre-inspection is carried out where our team checks that all elements are completed according to drawings, specifications and applicable building codes. We document any details that need to be addressed and ensure that the work is ready for independent review.
Each individual building component – such as walls, floors, ceilings and fixings – is visually and technically inspected. We ensure that there are no visible or hidden defects, that the correct materials have been used and that assembly has been carried out according to instructions.
Once the self-inspection has been completed, we book a meeting with the customer, client or external inspector. Together we go through the entire construction, compare with the documentation and discuss any questions or requests.
If deficiencies are discovered, a list of actions is drawn up. We address all points within the agreed time and communicate the status continuously. Our goal is always to deliver a flawless result – without compromise.
When all measures have been implemented, the final inspection takes place. This is carried out by an external inspector or approved by the customer according to agreement. If the result is approved, the project is considered completed and the house is ready for occupancy or further interior work.
Loose Timber House Project
At Hus i Bergslagen AB, we provide a modern, precise, and flexible solution for constructing loose timber houses (Lösvirkeshus). Our process is designed to support efficient on-site assembly without compromising on quality or customization. We deliver all structural components fully precut, labeled, and prepared according to your project's exact specifications. Each element is dimensioned and organized for optimal handling on-site, whether the assembly is carried out by your own team or a partner contractor. The house is then built element by element directly on the construction site. This method offers greater flexibility than prefabricated modules, especially in projects where access, transport, or customization requirements make factory-assembled elements less practical. Thanks to our detailed 3D modeling and labeling system, every part fits into place with high precision. We also provide comprehensive assembly instructions for each construction layer, from structural framing to insulation and finishing materials, ensuring a smooth and reliable building process.
Construction process
Step 1: 3D Model Generation
Based on architectural drawings (DWG/PDF formats), a full 3D model of the house is constructed. The 3D model is essential for material calculation, volume control, collision detection, and cost estimation. No offer is made without a completed and verified 3D model to ensure 100% material and cost accuracy.
Step 2: Volume Segmentation
The 3D model is divided into production and assembly volumes to optimize logistics and workflow:
For prefabricated builds, volumes are limited according to Swedish transport regulations (standard road transport dimensions).
For loose timber projects, volume segmentation is optimised based on the lifting capacity, number of assemblers, and site working conditions.
Step 3: Layer Structuring (Wall Section Decomposition)
Each wall element is structured in layers from exterior to interior:
-
Outside layers: exterior panel (cladding), lathing (ventilation battens), wind barrier (vindfolie)
-
Structural Frame + Mineral Wool Insulation
-
Inside layers: vapor barrier (plastic foil), installation wall + additional insulation, OSB board (structural sheeting, gypsum board (interior finish)
Step 4: Component Extraction and Labelling
Each layer is decomposed into individual components. In the frame structure, every stud, beam, and sill plate is separated. Every component is assigned a unique identification label (ID) linked to the 3D model database.
Labeling allows for precise sorting, packing, transport, and on-site installation without interpretation errors. All the elements composing each wall are packed together for easy handling and assembly.
Step 5: Assembly Documentation
For each prefabricated volume or composing element, detailed waterproofed assembly drawings are generated. Assembly instructions specify:
-
Element order
-
Component placement
-
Connection types (nails, screws, plates, etc.)
-
Fastening standards (e.g., distances, edge spacings)
Step 6: Floor Slabs and Roof Structures
Intermediate floors (slabs between levels) are produced and delivered following the same methodology (layered breakdown, component labelling, and assembly documentation).
Roof structures (takstolar) are fully prefabricated in the factory and installed on-site based on dedicated lifting and installation instructions.
Process Advantages
-
Full traceability from model to finished structure.
-
100% material accuracy – no surplus or shortages.
-
Optimized on-site work – rapid, error-free installation based on clear, step-by-step instructions.
-

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.
Product specifications
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.
