Award-winning Gryphon House is a stunning 5-bed, two-storey house built by owners Chris and Jenny Shepperd, using our TechVantage S timber frame system.

Design features

Set in a spectacular location in Warwickshire, it’s the details of this house which makes it so stunning. The house is timber frame clad in stone, with some fibre cement cladding and a slate roof. It incorporates beautiful features such as a floating, curved staircase, external balconies around the rear elevation, and a vaulted ceiling over the kitchen with a bridge to the bedrooms over the garage.

Large triple glazed sliding doors in four rooms lead to patios with balconies, providing a light, bright and sunny interior, and the incredibly popular inside/outside living feel.

As the chosen timber frame supplier, we needed to come up with specific solutions to integrate these features to help the couple build their dream home:

  • The staircase had proven a challenge for other frame designers, but we achieved it by cantilevering it and installing vertical timbers in the supporting wall to make it strong enough to support the weight.
  • The balcony was created by installing steel struts that fed invisibly into the timber frame, creating the floating feel that the Shepperds desired.
  • Similarly, the vaulted ceilings and overhead walkway were achieved thanks to strategic steel elements built into the structure.

Energy efficient

Energy efficiency was also at the forefront of design. The Shepperds chose our unique TechVantage S system because of the energy performance it would provide. TechVantage S is a breathable closed panel system fully filled with 140mm 035 timber rafter batt in the factory. The system is lined on the inside with a 50mm PIR Liner and service batten and plasterboard with a Thermo breather paper on the outside. This delivers a 0.15 U Value through the walls, while a Superglass loft roll was used in the roof to achieve 0.13 U value. A Superglass acoustic insulation in the internal walls and floor zone delivered a well-insulated energy efficient airtight new home.

The complete house achieved a SAP rating of 99, which is exemplary, and achieved the highest Passivhaus standard when tested for air tightness.

Building with timber frame offered a number of benefits to the Shepperds. The lightweight and flexible nature of the material meant they didn’t need all the supporting foundational components that would be required for other build methods. The flexibility of timber also meant they could make adjustments easily during the build process.

Chris Shepperd explains: “Frame Technologies offered flexible options for thickness of frame and level of insulation to achieve the kind of low U values we wanted. We approached other timber frame suppliers, but Frame Technologies was the only one to offer the energy efficiency we required at the right price point, while also being incredibly flexible and accommodating in their approach. Simon would pull out every stop to deliver on time and paid incredible attention to detail. There is a lot of value in that level of service.

“The craftsmanship of the cantilevered staircase is fantastic, and the end result looks effortless. Crucially, we got a house that we love, that does exactly what we wanted it to.”

This house is a brilliant example of a home that looks incredible, while also delivering on functionality and energy efficiency. If you’d like to know more about how you can build your dream home with us, contact us today.
