What customers say — Harpenden & nearby
★★★★★ 4.9 / 5 from verified customers
★★★★★

“Hip-to-gable conversion on our 1930s semi. I was nervous about the planning application but the specialist I found here had done dozens in our street and knew exactly what to submit. Project came in on time at 10 weeks. The new master bedroom is brilliant.”

James R. Harpenden
★★★★★

“L-shaped dormer on our Victorian terrace — created two rooms and a bathroom from what was a completely unusable loft. The comparison process gave me confidence I was paying a fair price. Building control sign-off came through with no issues. Absolutely transformed the house.”

Helen T. Manchester
★★★★★

“Velux conversion for a home office — budget-conscious option but exactly what I needed. Three quotes within a day, specialist was clear about what was and was not included. Finished in four weeks with full building regs certificate. Would definitely use again.”
