Alton Fusion Cedar Greenhouse Half workshop Half greenhouse
The Alton Durham T-Shaped Cedar Orangeries is an astutely designed, robust greenhouse - using the same construction method as the rest of the Alton Evolution range. The finish, attention to detail and amount of material used to manufacture it, is unprecedented at this price. All of the potential 'rot points' have been designed out of the greenhouse.
This greenhouse is guaranteed not to rot for 10 years. That said, we would recommend you treat your greenhouse every 3 years, this way your greenhouse could last 30, 40 maybe even 50 years.
Alton have taken their superior design know-how and superb craftsmanship to create this sylish and highly practical garden building.
The Alton Fusion 10 combines a greenhouse and workshop under one roof, both made from high-quality, pest- and rot-resistant Western Red Cedar. Each space has its own separate entrance — a lockable hinged door for the workshop and a sliding door for the greenhouse, with an optional internal sliding door between them.
The greenhouse offers excellent ventilation through an automatic roof vent and slatted side louvre, promoting healthy air flow, while the high eaves create a stable growing environment. It features toughened safety glass and screw-down timber bar capping for durability.
The workshop is well-lit with large windows and built from strong solid timber carcassing with tongue and groove cladding. Its roof is watertight with quality red felt, and you can add an optional timber bench for extra workspace.
