Write the first review

Did You Know? All of our Swallow Timber Greenhouses Include DELIVERY & INSTALLATION in the price!


The Swallow Combination Shed adds storage space to your greenhouse, somewhere to put tools, fertiliser, bean poles, bags of compost, and pots that aren't being used, out of sight.

Constructed with Thermowood®, which is heat treated Scandinavian timber that is very strong and has a long lifespan. The Combination Shed is an optional extra and cannot be purchased on its own.

Offering an additional 28sq ft of working area, the 6 x 4 Combination Shed, with shelving as standard, is a very valuable add-on to your greenhouse, but remember this shed can only be purchased in combination with a Swallow greenhouse.
