Extra space without the faff of a traditional extension, this Dunster House Addroom® 5m x 3m sits in the brand’s garden-room range as a conservatory alternative that competes with insulated garden offices and “sunroom” style pods. The pitch here is year-round usability: it’s fully insulated and double glazed, aiming to feel more like a proper room than a summer-only structure, while keeping the build quicker and less disruptive than masonry work.
Who is this for — office, gym, or a brighter lounge?
The built-in skylights are the headline feature, pulling daylight deeper into the room than standard side glazing alone, which suits desk setups, workout space, or a family snug that doesn’t feel gloomy. uPVC windows and doors with multi-point locking add reassurance if you’re storing kit or using it as a regular workspace. Outside, the composite finish is pitched as low maintenance, so you’re not committing to constant repainting.
- 5m x 3m footprint — enough for a desk zone plus seating, or cardio kit with clearance.
- Insulated, double glazed — better temperature control across seasons than basic summerhouses.
- Skylights included — more natural light where you actually use the room.
