Loft Conversions Designed Around Light, Space & Comfort

Space Up specialises in loft conversions across SE London, delivering bright, beautifully finished spaces that work exactly as you need them.rn
The Space Up 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.

What Our Clients Say

Real Reviews. Real Results.

Bedroom to dressing room conversion
“Convert bedroom into dressing room! Moving and replacing radiators. Insulate and plaster walls. Yuriy responded quickly to my enquiry. He visited within days to give an estimate and completed the work. He is polite, informed, extremely tidy and very competitively priced. Full knowledge of how certain work should be done. Overall, superb service and great value.”
Hallway, stairs and landing renovation
“Yuriy’s work is of high quality and we have been very happy with the standard of workmanship. Yuriy is always on hand to solve any issues that may arise and will always look for the best solution. Yuriy has delivered our work on time and to budget and we would have no hesitation in recommending his services.”
Stairs and landing repair
“Yuriy fixed our funhouse stairs which were as suggested by the name a little wonky! (to say the least). He did the job quickly, the work is excellent and it came in at the same price that he’d initially quoted. He tidied up beautifully and even swept up some of the pine needles that were still hanging about outside our front door. A total star – we would highly recommend!”
Full house refurbishment
“Yuriy (spaceup team did an excellent job of fully refurbishing our six bed Georgian end of terrace. Everyone was punctual, polite and good at their job. A special callout to Sergey (tiler) for his excellent work and plumber for his attention to detail. We’re really happy with the results, would hire Spaceup again to do side extension later in next year , and definitely recommend to anyone who wants good work quality .”
