Orpington

A-Z Builders provide loft conversions, extensions, and outbuildings across Orpington and the surrounding BR5 and BR6 areas. Orpington's mix of large detached and semi-detached homes makes it one of the most popular areas we work in for rear extensions and loft conversions — there's often significant potential to add real space and value to properties here.

Our team manages the entire process on your behalf, from liaising with architects and structural engineers through to obtaining building control sign-off at completion. We'll advise you from the very first visit on whether your project requires planning permission or falls under Permitted Development rights.

Loft conversions typically complete in 8–10 weeks and extensions in 10–14 weeks. All our projects come with a free site survey, itemised written quotation, deposit protection, and a 10-year guarantee covering both materials and workmanship. We carry comprehensive public liability insurance up to £1,000,000.

With over 70 five-star Checkatrade reviews and more than two decades of experience, A-Z Builders are a trusted choice for homeowners across Orpington. Contact us today to arrange your free survey.
