Forest Xtend 2.5 Insulated Garden Office 2.54m x 2.9m (97mm)
Overview
The Forest Xtend 2.5 is the smallest insulated garden office in the Xtend range, measuring 2.54m x 2.9m. Built with Structural Insulated Panels (SIPs) in the walls, roof and floor, it’s a compact but genuinely year-round space, ideal as a home office, studio or hobby room where a full-size garden room isn’t needed or the plot won’t allow it.

Dimensions

- Wall panel thickness: 97mm SIP core
Construction
The wall SIPs sandwich insulation between oriented strand board for a 97mm core, with premium kiln-dried tongue and groove external cladding on a supporting frame. Internal cladding is pre-cut MDF, already primed and ready for your choice of colour. The floor SIP is left uncovered, so you can add carpet, laminate or another finish of your choice, supported by wrapped floor bearers that keep rot and rising damp at bay.
Treatment & Guarantee
The timber is supplied untreated and needs treatment upon assembly and annually thereafter with a recommended wood finish such as Sikkens or Osmo. The structure carries a 15-year structural guarantee, and the EPDM roof a separate 50-year guarantee.
Doors & Windows / Security
A single glazed door provides access, fitted alongside a window for natural light. All glazing is A-rated and toughened for safety. The reinforced door frame includes a key-operated 7-point multi-lock with Ultion three-star security barrel, and the opening window is also key-lockable.
Assembly Information
Pre-made SIPs and pre-cut cladding simplify construction, and Forest Garden’s professional installation service is available if DIY isn’t for you. Interior battens leave space for wiring and recessed lighting should you wish to add mains electrics later.
