House Extensions

Create more space in your home with a Barnhouse House Extension. Designed around your existing property, our extensions provide practical additional living space while combining modern design, quality materials and efficient construction.

Built using SIP panel technology, our extensions provide excellent insulation, structural strength and energy efficiency. The system also allows for an efficient construction process while maintaining a high standard of comfort and durability.

Whether you need a larger kitchen, dining area, living space, home office or additional bedroom, each extension can be designed around the way you use your home.

Barnhouse extensions can be custom-designed to suit your existing house, available space and requirements. Options can include different exterior cladding, glazing, roofing, flooring, insulation and interior finishes.

From the initial design through to construction and installation, Barnhouse provides a practical extension solution designed for homes across Ireland.
