Double Storey Extensions

Double Storey Extensions and Renovations London

Atomic Build offers life-transforming double storey extensions to residents across Greater London. If you’re feeling constrained by your current house and want more room to stretch your legs, a double storey extension can be the perfect solution.

While adding a second storey to your home is not a quick process, it can be a sensible alternative to moving house when you’re ready to size up. We offer industry experience, detailed consultation, and construction expertise for all extension projects.

A double storey extension is highly flexible, with homeowners able to add valuable living space, extra sleeping space, storage space, office space, and more, depending on their needs. Regardless of your budget constraints, we will take time to match your requirements with creative lifestyle solutions that work.
