Looking for a 16x12 garden room? Many off-the-shelf garden rooms rely on thin framing and cheap overlap cladding. At Ecco Sheds & Lofts, we custom-build premium timber garden rooms to order in Derbyshire—with heavy-duty cladding options from 16mm upward and installation by our own team.

Need it exactly 16ft by 12ft? No problem. Want glazing on one side only, bi-fold access, or a layout that suits a corner plot? We can do that too. Our craftsmen will tailor door and window positions to your garden—ideal for hosting large gatherings, installing a full garden bar, or a games room.
