Garden rooms are one of the most practical ways to add usable space to a Henley property without touching the house itself, which matters a great deal here given how many homes in the town sit within the conservation area or carry listed status. A garden room in the garden rather than an extension on the house avoids much of the sensitivity around altering historic fabric, though any planning permission or conservation area considerations for the garden structure itself still need checking with South Oxfordshire District Council before work starts, particularly on plots close to the river or within the historic core.
The gardens we work in around Henley vary enormously. Riverside plots are often long and narrow, sometimes with a change in level down towards the water, while the larger detached houses towards Remenham and the Chiltern edge tend to have more generous, regular grounds. Both need the same groundwork done properly: a level, well-drained base, correctly specified insulation for year-round use, and weatherproofing that will hold up through a Thames valley winter, not just look finished on the day of handover.
We manage a garden room build from base to handover, structure, insulation, external cladding and internal fit-out, with electrics carried out by the qualified electrician we work with. Everything is designed in CAD first so you can see the finished room, its proportions against the garden and its relationship to the house, before groundworks begin. Lead time for the joinery elements runs to around six weeks once the design is signed off, alongside the base and structural work that has to happen first.
