FRAME TECHNOLOGIES

Versatility in terms of design, costs and package options makes timber frame a popular method for self builders.

Key benefits

● There are lots of suppliers out there offering a range of package options specifically tailored for self builders.

● You can be involved in as much or as little of the project as you want – from simply specifying the manufacturer to supply and erect the frame right through to buying a turnkey package where the company looks after everything for you, handing you the keys to your new bespoke home at the end.

● Buying a package upfront means you’ll confirm costs before work starts, offering you more certainty for overall project budgeting.

● The amount of work completed on site is flexible. An open timber frame will have the insulation, services, windows etc installed on site. Alternatively, closed designs have more elements fitted in the factory.

● Off-site manufacture allows groundworks and foundations to progress on site while the structural frame is being cut.

● Once delivered to site, the shell can be put together very quickly.

● Good energy efficiency and airtightness are easily achievable.

Main considerations

● Most turnkey packages don’t include work on site before the timber frame arrives, such as groundworks and foundations.

● Changing things once the shell is in place can be complicated and costly – especially if you’ve got a closed panel system.

Bob and Mandy Williams decided to self build after they couldn’t find a suitable property on the market in the area they wanted to live. After some research, they chose to adapt one of Potton’s timber frame designs into their ideal home. The couple worked with one of the company’s in-house designers to make extensive modifications to the design they liked, which was then put through planning by the Potton team.

Work on site got underway in March 2018; the couple were particularly impressed at just how quickly the timber frame went up on their plot. Bob and Mandy moved into their new home in December the same year.

The finished property features a white rendered exterior and lightfilled interiors thanks to large windows and glazed doors. The pale grey composite fenestration and aluminium rainwater goods create a modern look. An air source heat pump works alongside underfloor heating to create a comfortable home, which the pair are delighted with.
