The Biohort AvantGarde range of sheds are made from top quality hot dipped galvanized steel with a multi-layer coating for extra protection.

The AvantGarde features a skylight just below the highest point of the roofline. Tough Perspex glazing allows light into the shed even with the door shut.

The door is designed to fit onto any of the walls and can be hinged either on the right or left as necessary. The door is complimented by a gas-assisted spring damper and a 3-point locking mechanism.

Simple and straightforward to install with full instructions and fixings included within the package. Comes complete with integrated gutter, ventilation slots to help prevent condensation build up and some handy tool racks and accessories as standard.

Biohort offer a 20 year guarantee against rust perforation on all of their buildings.
