> Extension Types
What Kind Of Space Do You Need?
Rear Extension
The most popular extension type in Glasgow. Extend into your garden to create an open-plan kitchen-diner, a larger living space, or a dedicated dining room flooded with natural light through bi-fold or sliding doors.
Single-Storey Extension
Versatile and cost-effective, single-storey extensions work across a wide range of Glasgow property types — from traditional sandstone tenements to modern new-build semis. Ideal for kitchens, utility rooms, and living areas.
Double-Storey Extension
Maximise your footprint with a two-storey extension that adds living space on the ground floor and a bedroom or bathroom above. Excellent value when building costs are shared across both levels.
Wraparound Extension
Combining a rear and side return extension, a wraparound creates a dramatic transformation of your ground floor. Perfect for unlocking the full potential of period properties and Victorian terraces.
