Compare claddings, roofs and glazing. Each guide covers pros, cons and the price impact.
Western red cedar is the UK's most popular premium cladding for garden rooms — naturally rot-resistant, dimensionally stable and weathering to a soft silver-grey over 18–24 months.
Siberian larch is a hard-wearing, knotty timber with a warm honey tone that silvers over time. A more affordable alternative to cedar with similar longevity.
Structural Insulated Panels (SIPs) sandwich rigid foam insulation between two layers of OSB for a thermally efficient, airtight shell. The gold standard for year-round garden offices.
Flat (or low-pitch) roofs with EPDM rubber or fibreglass membranes are the most common garden room roof — modern looking, cost-effective and ideal for permitted development height limits.
Pitched roof garden rooms (typically 15–30°) offer a more traditional cottage look, longer roof lifespan and the option of a vaulted internal ceiling for extra airiness.
Floor-to-ceiling glazing or full-front sliding doors maximise garden views and natural light. Best paired with solar-control glass and overhanging eaves to manage summer heat.
