How much do our
buildings cost?

Our Process

Here at Stonehouse we do it differently to most as we are fully bespoke, no two projects are the same! 

Our experienced design team are very happy to discuss your individual requirements over the telephone or via a videocall. They will listen to your needs, advise, design and produce a relatively accurate costing for your dream bespoke garden building.

If this sounds of interest, most of our customers take advantage of our mobile showroom and have a full site survey! We offer this service free of charge and our designers are more than happy to design your bespoke garden building in the comfort of your own home.

We aim for you to receive your bespoke design along with a fixed price quotation within 48 hours of your consultation!

Whilst we can provide relatively accurate quotations through telephone consultations. Most of our customers prefer to book a home survey to discuss all of the possible design options, see samples and understand fully what is available to include into your bespoke design.
