Built in the UK from the finest materials and supplied with a 15-year guarantee, the 20' x 10' Windsor Groundsman Wooden Garden Workshop Shed (6.09m x 3.18m) offers unbeatable garden storage and makes the ultimate home workshop too.

Constructed in the UK from 12mm shiplap cladding on a 44 x 27mm frame, this extra-large wooden shed is certainly made to last. The floor and roof are built from equally-robust and weathertight 12mm tongue and groove, the latter including a premium felt cover for complete weatherproof protection. The roof's apex design offers increased headroom, the opportunity to store taller items, and facilitates extremely efficient rainwater runoff, while an attractive finial enhances the shed's already smart appearance.

Pressure treated and supplied with a 15-year anti-rot guarantee, once a waterproof top coat is applied this garden shed will provide unbeatable weather-resistant protection. All of the wood is FSC®-certified, so only sourced from sustainable, well-managed forests.

This top-of-the-range garden workshop has 2 points of entry. The main double doors offer storage-friendly access to the interior, are ledged and braced for extra strength, and fitted with a hasp and staple to keep expensive machinery safe (padlock not included). There is a personal access door too. This is also ledged and braced, and fitted with a pad bolt (padlock not included) to maintain security.

Three opening windows provide lots of natural light and the opportunity for welcome ventilation on a hot summer's day. They are all made from styrene, which is completely shatterproof and far safer than conventional glass. 

This workshop shed has a modular design so the doors and windows can be fitted in a variety of positions, according to requirements. See the different product images above for examples.

Windsor wooden sheds come in a range of styles and sizes. Fixings and instructions are included for a simple assembly.

Delivery is free to most UK addresses.
