The My Den in Western Red Cedar cladding — the same fully insulated, double glazed build with a natural cedar finish that weathers beautifully over time.

A UPVC single door and double glazed windows sit alongside 90mm insulated walls and laminate flooring for a warm, ready-to-use space. Pre-assembled modular panels and an included assembly service make for a hassle-free build, backed by a 15-year anti-rot guarantee* for lasting peace of mind.

The MyDen is insulated in the walls, floor and roof with high-performance multi-foil. Its layered design traps heat in the cold months and reflects it in summer, achieving U-values comparable to 120mm of glass wool, in a far slimmer profile that leaves more room inside.
The heavy-duty metal roof adds a 40mm insulated core with a steel outer shell and white-gloss interior, built to shrug off British weather, season after season.
16mm Western Red Cedar boards are fixed with a secret-nail profile, so the face stays clean with no exposed nail heads. Cedar is naturally rich in oils that resist moisture, decay and insect damage without chemical treatment, and needs far less maintenance than standard softwood. Left alone it weathers to a distinctive silver-grey, or oil or stain it to keep the warm honey tone of the fresh timber.
Western Red Cedar is naturally rich in oils that make it resistant to moisture, decay and insect damage without the need for chemical treatment. Left untreated it weathers to a distinctive silver-grey over time, or it can be stained or oiled to preserve the warm honey tone of the fresh timber. Either way, it requires far less maintenance than standard softwood cladding and improves in character as it ages.
