"Apex Builders completely transformed our Dulwich Victorian with a rear extension and loft conversion. The quality of workmanship is outstanding — every detail was considered. Tom and his team were professional, communicative, and delivered exactly on schedule. Cannot recommend highly enough."
"We hired Apex for a full renovation of our Clapham terrace. New kitchen, two bathrooms, rewiring, the works. They kept to the timeline, the budget was transparent from day one, and the finished result is magazine-worthy. Our neighbours keep asking for their number!"
"Had our loft converted by Apex Builders — dormer with en-suite in Balham. Excellent communication throughout, very tidy site, and the finished room is absolutely stunning. The staircase design was particularly impressive. Would use again without hesitation."
"Apex built our wraparound extension in Peckham and it's genuinely transformed how we live. The open-plan space is incredible — so much light. They handled the planning application, party wall, everything. Stress-free from start to finish."
"Third project with Apex Builders now — they did our kitchen five years ago, then a bathroom, and just finished a rear extension. Consistently brilliant quality and fair pricing. They're the only builders we'd ever use in South London."
