Forest Xtend 3.0 Plus Garden Office

A Forest Xtend 3.0+ garden building is 9ft by 9ft in size and offers a great opportunity for you to make the most of your garden whatever the weather. A practical structure that can be an office, studio, or hobby room away from domestic distractions.

The attractive design of the Xtend 3.0+ is also very energy efficient, built with structural insulating panels and fitted with double glazed doors and windows. This ensures the cabin's interior warmer during the winter and cooler during the summer, is easily accessible and a welcoming environment, bright with sunlight streaming through the generous glazing, and the windows open for ventilation if required during the warmer months. 

Forest's weatherproof external tongue & groove cladding through the Xtend building can be painted to complement your garden but the timber is kiln dried and needs no treatment over its long life span. Primed MDF paneled walls and ceiling create an attractive interior and, to ensure the security of any valuable items, the easily accessible double doors have a 7-point multi-lock.

The flat pent roof could have been covered in traditional felt but Forest has chosen durable EPDM rubber that has a far longer life expectancy, and does not tear, rot or blister. Structurally guaranteed for 15 years, this is a UK manufactured garden building and, because only high-quality materials have been used, a 15-year structural guarantee is offered.
