Having the double doors moved to the eaves elevation, along with the large windows on each side of the doorway allows flowing light to cascade throughout the building. This unique design offers many uses for the hobbyist or professional to work safely without compromises. We are sure to have the right size for you!

All of our products are made from quality materials sourced from sustainable forestry, we believe in our products so that’s why we put our name on it! We do not use any OSB, Chipboard or MDF, we do use real wood from floor to roof in every build, you can also customise your new garden building by adding a choice of extras found above, we will also include a full installation fixings kit with every garden building purchased.


Our garden buildings offers great value for money in all aspects of the construction, we think all of our products from all ranges sell them selves whether you choose the shiplap, loglap or overlap style of building. The whole experience from Rainbow should be the easiest online choice you will make – for example: We tell you every thing you need to know from the start, no promises we cannot keep or false delivery dates unlike most competitors. The timbers used are all stress graded with the key feature of our unique four corner rounded edged framing used in the building process thus reducing splintering. When choosing the right building please take your time to read and study the details of this superb Rainbow product.

Please note all deliveries are kerbside only*

Delivery vehicles vary from product to product but we rely on the customer to make us aware of any restrictions when ordering your product. Generally 10ft wide clear road access with no height restrictions is the ideal, but with a wealth of experience we can normally get over most obstacles as long as we are prepared. Sometimes an additional fee may be required. Should you have any doubts please contact a member of staff to discuss further.

Our delivery periods vary depending on the seasonal demand, but as a general rule standard buildings such as the more popular garden buildings are often available upon a shorter delivery period (15 Days*) than labour intensive, made-to-order products.

To find the current delivery period of any individual product, please contact one of our sales staff. The period given is the current delivery target nationally, however delivery could also occur an element sooner or later than stated due to transport logistics. For example, a central, highly populated location is likely to be serviced more often making delivery quicker than a less visited area location such as parts of Scotland,Wales,Devon and Cornwall.

Advance notification of an exact delivery date is issued to the customer either by ourselves or by the delivering party nearer the time of an order, usually by telephone or letter prior to the proposed date. Should the date offered not be convenient, you are able to request a re-schedule without additional charge. Deliveries are made weekdays only excluding bank holidays.

If you require a product by a set date – such as a birthday, or you have access concerns for the passage of any large vehicle, please contact one of our sales staff for advice and assistance.
