Structural timber frame extensions designed and built to your brief; additional living space for homes across Carmarthenshire and South West Wales.

Young Carpentry designs and constructs timber frame single storey extensions for residential properties across Carmarthenshire and South West Wales. We handle the full carpentry package, from sole plates and wall frames through to roof structure, insulation fitting, OSB racking and any external cladding or internal boarding. Timber frame builds are fast to erect, thermally efficient and well suited to the rural and period properties common across this part of Wales. We work from architectural drawings or can advise during the design stage to make sure the frame is practical to build and finished to a high standard. All work is carried out cleanly and with minimal disruption to the main property.
We specify breathable membranes, treated structural timbers and appropriate insulation values for the exposed conditions common across Carmarthenshire; builds that perform properly over the long term.

Most single storey rear extensions fall within permitted development rights, though this depends on the size, your property type and whether you're in a designated area. We can advise based on your specific site and will work from approved drawings where full planning permission is required. We recommend confirming with your local planning authority before work begins.
