Cedar Garden Rooms in Reading
Insulated garden rooms, offices and studios built across Berkshire. Free surveys, fixed written quotes, tidy workmanship.
Reading Garden Room Co. builds cedar-clad garden rooms across Reading and Berkshire — Western Red Cedar and thermowood buildings that sit in a leafy Caversham or Sonning garden like they grew there. Cladding is the personality of a garden room, and timber remains the material that makes a building feel like part of the garden rather than parked in it.
We'll also talk you honestly through the alternatives — composite, render, painted boards — because the right answer depends on the garden, the house and how you feel about timber's greatest feature and biggest argument: the way it ages.

Timber options we clad in
Western Red Cedar
The classic — warm tones, natural oils that resist rot, and a scent that makes the build week smell wonderful.
Thermowood
Heat-treated Scandinavian softwood — cedar's stability at a friendlier price, in slats or boards.
Slatted screens
Horizontal slats over black membrane — the contemporary look that pairs beautifully with big glazing.
Mixed elevations
Cedar where you see it, economical boards where the fence does — designed, not compromised.
The silvering question
Untreated cedar weathers from warm amber to soft silver-grey over two to three years — faster on sun-facing elevations. Half our clients choose cedar *for* that; the other half want the amber kept, which means UV-protective oil roughly every 18 months. There is no third option, and anyone selling 'maintenance-free natural cedar' is selling the first eighteen months. Thermowood silvers slower, composite not at all — we'll show you samples aged at different stages so the decision is made with open eyes.
Cladding adds £1,500–£4,000 across our range depending on choice — itemised in every quote so the trade-off is yours to make.
