Now, more than ever there is a huge demand for creating extra space at home. Newton and Frost Timber Buildings can help you create the perfect garden room that is high quality and stylish to fit your space.

Our in-house team can offer a free site visit to discuss your requirements in more detail. We then prepare some visuals for you to see your garden room idea. Once we have your approval, we can then start to prepare your quotation for your garden room.

My wife couldn't be happier with her new art studio, so pleased we stumbled across Newton & Frost as they were brilliant from start to finish.

Very impressed by the whole process of buying a workshop from NFF Equestrian. Quality build, good value for money, great workmanship and friendly and helpful service. Highly recommended!

Thanks once again to both of the lads who did the job. They are a credit to the company.

We visited the NFF yard and after speaking to staff and having a look around we ordered a 4x3 garden studio.  The team were all very friendly and easy to deal with and I would recommend them without hesitation - the whole process was very easy, and as they manufacture their own buildings everything went smoothly and without incident. We are very pleased with the final product.
