Loft Conversions

Loft Conversions Designed Around Light, Space & Comfort

Your loft is unused potential waiting to be unlocked. A well-designed loft conversion adds a full room — and significant value — to your South East London home without losing any garden space. SpaceUp specialises in loft conversions across SE London, delivering bright, beautifully finished spaces that work exactly as you need them.
The SpaceUp Standard
Loft Conversion Types We Offer

Velux Loft Conversion — from £35,000

The most cost-effective option. Velux windows are installed into the existing roof slope with no structural changes to the roofline. Ideal for creating a bright bedroom, home office, or reading room.

Dormer Loft Conversion — from £50,000

A box-shaped extension built out from the sloping roof, creating vertical walls and significantly more usable floor space and headroom. The most popular choice for a full bedroom with en-suite.

Hip-to-Gable Conversion — from £55,000

Ideal for semi-detached or detached homes with a hipped roof. The sloping hip end is replaced with a vertical gable wall, dramatically increasing the internal space.

Mansard Conversion — from £60,000

The most extensive option — the rear roof slope is replaced with a near-vertical wall. Maximum space gain, often used for master bedrooms or studio apartments.

Bathroom fitting
“SpaceUp and his team were excellent from start to finish, providing a solution to an on-going problem we’ve had with our bathroom which previous tradesman had not been able to fix. Yuriy came to inspect, provided a clear plan of action, a competitive and transparent quote and carried the work out to a very high standard. He was great to communicate with and made the whole project run very smoothly. Will be my go to tradesman for future work I have and would fully recommend him to others. Thanks again!”
