The largest in this range, the 6ft x 20ft Jay Potting Shed is a splendid structure, traditionally built but taking full advantage of modern techniques and materials.

Heat treating timber to extract moisture and resin is a Scandinavian technique that results in ThermoWood® which is highly resistant to warping and rot. This means it's perfect for garden buildings, and only Swallow products take advantage of ThermoWood's excellent qualities.

This is a potting shed that offers a great environment to serious gardeners. There are roof vents to control the temperature and humidity, they have automatic openers and so operate when you are not present.

Staging lines the front of the shed while two shelves are behind you, an additional shelf can be added if required above the staging, and you can also install guttering to collect rainwater for re-cycling. Generous 4mm toughened sealed glazing allows in plenty of light.

There's more than adequate room for storage which is also an important consideration, and for security the door has a mortice lock. So it's clear that Swallow have really thought about making the design, fixtures and fittings very functional as well as attractive..

If you have serious gardening ambitions, then this potting shed must be a delight and, with delivery and installation included, the price is delightful as well.
