Extending a house is a common solution in Luxembourg for creating additional living space and increasing the value of your property. However, such projects require careful planning and the involvement of a certified architect, as most communes require professionally prepared plans for obtaining a building permit.

At BIV Immo, we work with a network of experienced architects with different language skills who can support our clients throughout the entire process, from the initial ideas to obtaining the necessary approvals.

A house extension is a complex project that requires precise coordination between different trades and construction stages — including windows, plumbing and heating systems, electrical installations, flooring, walls, and finishing works.

With our experience in construction, renovation, and transformation projects, BIV Immo provides clients with a complete solution and a single point of contact throughout the entire process. Our team ensures that every detail is carefully managed and that all works are delivered with quality and efficiency.

Building an extension can be a challenge, but with the right partner by your side, it becomes a smooth and rewarding experience.
