A garden room is one of the most practical ways to add usable space to your property without the disruption of a full extension. Most are timber-framed with insulated walls, floors and roofs - making them genuinely usable in winter not just summer.
Size matters. A garden office typically starts at around 2.4m x 2.4m but anything smaller than 3m x 3m can feel cramped once a desk and shelving are in. For a garden gym or garden studio the extra floor area pays for itself quickly.
Check the insulation values before you buy. A well-insulated room should have at least 100mm of wall insulation and a U-value below 0.28 to stay warm without running a heater constantly.
Planning permission is not always required. Most garden buildings under 2.5m fall within permitted development - but always verify with your local authority first.
Cladding choice affects longevity. Pressure-treated timber lasts significantly longer than untreated softwood and needs far less maintenance over time.
