Our Grendon Underwood showroom is only 10 minutes from the Graven Hill site which presents the largest opportunity in the UK for people to build their own home. This idyllic spot is situated around a wooded hill just 3 miles from junction 9 of the M40. Graven Hill has outline planning for 1900 new homes, shops, offices, a primary school and a pub. We would like the opportunity to talk to anyone who is interested in buying a plot and hope we can help in designing your dream home. For more detail on the Graven Hill site please CLICK HERE.

Saturday Appointments

As Saturday is the busiest day for our showrooms and we would like to give you the time and attention you deserve, please note that Saturday visits are by appointment only. We’d appreciate it if you can keep to your appointed time purely as this ensures that you have individual time to ask specific questions for your project rather than listening to details of someone else’s!

We’re available to take appointments for Saturday mornings (as well as Tuesday to Friday) but we’re unable to answer the phones on a Saturday morning, so please book early to avoid disappointment.

As you may be travelling some distance to see us and we want to give you the best service possible, it would be helpful whatever day you are visiting if you could please call us prior to your visit to discuss your project in detail so that we can have all the information you require to hand.
