Our Methods:

Timber Frame

Quite apart from its outstanding properties of insulation and air tightness, timber frame construction has many other important advantages as a building material.

Design Flexibility

Timber frame can easily adapt to form complex shapes, and is able to bridge clear spans of 6 metres to form quite large rooms. It is also very adaptable on site with alterations being easily made up to the plaster boarding stage.

Quality Control

All the panels are produced by accurate machinery under factory controlled conditions.

Speed of Build

When delivered to site, the panels fit perfectly together and are quick and easy to assemble. A simple 3 bedroom house can be watertight within two working weeks from delivery of the panels.


All load bearing components are made from stress graded timber and subject to load bearing analysis from an independent structural engineer. Each panel is braced by a sheet of oriented strand board (OSB) and is very rigid.

Tolerant of Movement

As well as being strong, it is also able to absorb small movements in the foundations, should they occur. A conventional house made from brick and block materials will show cracking if there is any subsidence below the building. A timber frame does not.


All the structural timber and OSB is sourced from managed softwood forests. It’s embodied CO2 is a fraction of that of traditionally built houses. A small timber frame house will save about the same amount of CO2 in construction, as would be used driving 15,000 miles!

Air Tightness

Heat loss from buildings can occur in three ways: radiation and conduction, which can be overcome by improving insulation, and convection, i.e. draughts, for which air tightness is the essential solution.

Our methods of draught proofing include:

Each timber frame panel is sealed to the sole plate below, the rim beam above, and to each neighbouring panel. In addition, each block of insulation is sealed to the internal faces of the panels.
Joins in the wall panels are sealed with a high tack, long life adhesive tape. The same applies to the edges of the membrane at all window and door openings, and any other breaks in the continuity of the material such as ducts, light fittings etc. This is meticulous work requiring great attention to detail.
The third and final barrier against air leakage is the wet plastering of all rooms in the house. This effectively seals the walls and ceilings so long as care is taken whenever there are openings in the plaster for ducts, power points etc. Windows and doors must also themselves be well sealed.


Ventilation is very important when building such an airtight home. We use a Mechanical Ventilation & Heat Recovery (or MVHR) system, which ensures high air quality and helps to prevent condensation issues. MVHR also plays an important role in conserving energy in our buildings by recovering heat from extracted air and transferring it to the incoming air.
