GRAVEN HILL SELF AND CUSTOM BUILD DEVELOPMENT AT BICESTER

Total Home Environment are vey excited to be so close to the amazing Graven Hill development site in Bicester. We are one of the vanguard suppliers, having our systems installed within four of the first 10 homes being filmed by Grand Designs.

Graven Hill is a development site with a difference - 1,800 plots of land for sale with the opportunity of building anything from a first home in detached, semi-detached or mews style, a rural family home or a retirement home to downsize to.

An old MOD site, Graven Hill has a beautiful landscape which includes woods and wetlands. The Graven Hill Development Company (GHDC) have ensured that the Masterplan makes a proper community, rather than just rows of boxes. There will be a pub, school, community centre, green, cycle paths, play areas, allotments and other opportunities for businesses to accommodate a cafe, other small retail and office projects as well as perhaps a pre-school unit. The GHDC are encouraging cutting-edge design as well as the use of energy efficient materials, which is where Total Home Environment comes in.

We help people to make informed choices on their sustainable technology journey, so as a local company, we can:

  • design and supply air source heat pumps
  • design, supply and install central vacuums
  • design, supply and install heat recovery ventilation
  • design, supply and install air to domestic hot water heat pumps.
We ensure the correct products are supplied by providing the following local services:       
 Total Home Signs

Grand Designs The Street As Seen

  • room-by-room heat loss reports (ensuring the most appropriate heat source is specified for your home)
  • SAP Appendix Q reports (ensuring your home meets Building Regulations)
  • MCS Certification (enabling you to apply for money back from the government through the Renewable Heat Incentive)
  • 3D CAD designs (so that the ventilation and vacuum systems are designed with the most efficient routes and materials).



Have you seen the recent series of GRANDDESIGNS: The Street? We were happy to see that four of the 10 self-builders were our clients! They chose the following products to be in their homes:

Watch this space for case studies!

We have also been chosen to partner with Build It Magazine who, to celebrate their 30th Birthday are completing their own self-build! We will be providing all the heating, cooling, domestic hot water and ventilation of the house with our flagship product the HPV Series heat pump ventilation system.

You can follow it's progress within the Build It Magazine and their dedicated website.


There are various routes to purchase a plot of land at Graven Hill and you can do as little or as much of the work yourself. Total Home Environment will support your heating, ventilation and cleaning needs all the way through your project. Do go and visit the Graven Hill website for more information on the current availability on plots and the criteria which you will need to meet in order to reserve a plot. Good luck!
