Expanding Your Home
Gain extra space without major construction: ground-floor extensions, second stories, and add-ons next to your home, featuring a bolted galvanized steel frame and sandwich-panel walls. A lightweight, quick, and dry construction process.
Types of Expansion
The StarModul system is designed to expand homes built using any construction method, not just prefabricated homes.
An extra bedroom, a larger living room, or a new kitchen attached to the house. The structure rests on its own lightweight foundation.
One more story on top of the existing house. Steel is lightweight, so the added load is much less than with brick or concrete, although you should always check with a structural engineer to make sure the existing structure can support it.
A study, an office, or a guest room in the garden—without altering the house. Check out the bungalows and prefabricated modules.
Porches, covered patios, or enclosures that turn an outdoor space into another room in the house.
Why Steel?
Galvanized steel tube and sandwich panels: much lighter than a traditional structural addition.
The parts arrive pre-assembled and are bolted together on site. Fewer weeks of construction, less dust, and less debris.
Since it's a dry construction project and a short one, in many cases you can continue living in the house while it's being expanded.
Walls with a thermal transmittance of 0.155 W/m²K: the new section provides better insulation than many existing homes.
Exterior, roof, and interior finishes that match your home—or with a contemporary look, if you prefer.
Patented bolted connectors: a clean installation using hand tools and no on-site welding.
Before You Begin
Every expansion begins with a site visit and a technical study. These are the key factors that determine the solution:
An addition requires a design plan and a building permit: we explain this in the section on permits and procedures. You can find the details on how the facade and roof meet in the construction details.
How do you want it?
We'll send you the frame, the panels, and the plans so your contractor can assemble them.
Our team is assembling the structure, the facade, and the roof of the addition.
We take care of everything: the design, permits, construction, connection to the house, and finishing touches.
The price depends on the square meters, the type of addition, and how it connects to the existing house. Request a quote with photos and measurements of your house.
Step by step
Actual Works
Yes. An addition requires a technical plan and a building permit from the city, and it must comply with the zoning regulations for your lot (buildable area, height limits, and setbacks).
It depends on the existing structure and foundation. A technician must assess each case individually. The advantage of steel is that the new structure weighs much less than a traditionally built one.
Yes. The StarModul system is compatible with brick, concrete, or any other type of house. The connection to the existing house is designed as part of the project.
In many cases, yes, because it's a dry construction project and takes less time. It depends on what parts of the existing house will be affected; we'll go over that with you when we draw up the plans.
With installation included, on-site at locations about 2 hours and 30 minutes from Lleida, and as a turnkey project in the provinces of Lleida and Tarragona. Elsewhere in the world, we can ship you the kit so your contractor can install it.
