Hip-end side extension on our 1950s pebbledash semi in Hereford. Glazed corner of the extension brings southerly daylight deep into the plan. Job done for £120000 over 16 weeks. Trial pit done day one to confirm foundation depth was workable.
Compared four extension builders through BestBuilders for the Hereford job. Picked the firm whose CAD drawings showed every junction in 3D before signing. CCTV drain survey on day one, no surprises with hidden services. £60000 all-in, scaffold-free for half the schedule. EPC went up two bands thanks to the new spec.
A summer and a winter on, the new space holds temperature without the boiler kicking in. Builder we found via BestBuilders in Hereford persuaded us into a wider opening to the original house - the flow is so much better. Total £83400. Stamp duty saved by extending out rather than moving up.
