The installation timelines vary depending on the type of construction. A dormer window can typically be installed within one day, providing a quick way to add space and light to your home. A roof construction is usually made watertight in one day and fully completed on the outside within three days. Extensions take longer, with an average installation period of two to three weeks. These timelines ensure minimal disruption while maximizing living comfort.

Prefab construction involves building parts of the dormer window or roof extension in a controlled workshop environment before installation. After agreeing on the offer, measurements are taken at your home, and detailed construction drawings are prepared. The prefab elements are then manufactured in the workshop, ensuring high quality and precision. Once ready, these components are transported to your home and installed, often within a single day. This method reduces on-site construction time and disruption while maintaining excellent craftsmanship.

Planning and executing a home extension or roof modification involves several key steps. First, you develop the idea for your desired expansion, such as an extra bedroom or home office. Next, initial contact is made with a contractor who visits your home to discuss your wishes and feasibility. Then, a clear and detailed offer is prepared based on your requirements. Upon approval, precise measurements are taken, and construction drawings are created. The building process follows, with prefab elements manufactured off-site if applicable. Finally, the project is completed with installation and finishing touches, followed by aftercare and warranty support to ensure your satisfaction.
