What Aberdeen Homeowners Say About Our House Extension Specialists
Larger Permitted Development extension on our Victorian terrace in Aberdeen. Two-storey gain - utility on the ground, en-suite bedroom on the first. Cavity-tray detail done properly. Final cost £61200 fully fitted out. Party wall agreement handled by their consultant - smooth process.
Compared four extension builders through BestBuilders for the Aberdeen job. Selected on the depth of the spec - 28 pages versus the cheapest at 4 pages. Permitted Development route confirmed via a Lawful Development Certificate before any digging. Came in £2235 under quote because the foundations were shallower than feared. Daily 5pm site walk with the foreman, weekly progress on the spreadsheet.
Through a full freeze-thaw winter, no movement around the new openings. Builder we found via BestBuilders in Aberdeen specced higher-grade glazing than we asked for - winter heating bills are noticeably lower. Total £63660. Insurance happy with the building control completion certificate.
