Delivery & Returns

Our delivery times can vary throughout the year depending on demand. As a guide, our most popular standard cabins typically arrive within 4-8 weeks, while more bespoke and made-to-measure buildings may take a little longer due to the additional craftsmanship involved.

UK Mainland delivery is free to most locations.
However, as we work with a range of suppliers who have different delivery policies, we recommend contacting us for an accurate delivery quote to your postcode—especially if you are located in Devon, Scotland, the Scottish Highlands, Northern Ireland. 

If you're not completely satisfied with your purchase, you can return items within 30 days of delivery for a full refund or exchange (terms and conditions apply), provided they are unused and in their original packaging. Please contact our support team to initiate a return.
