Passive Design is efficient and sustainable.

Passive House is based on the principle’s that more can be done with less. More comfort and higher efficiency, with less environmental impact and lower running costs. Building passive requires us to think differently about how we can harness the power of natural resources in conjunction with innovative construction methods to improve the structures performance.

Thermal Bridge free construction

Thermal bridge free construction aims to eliminate uncontrolled temperature changes which is paramount in the efficiency and comfort of your home.

Penetrations must be kept to an absolute minimum, and where this is impossible, the use of low or non conductive materials should be selected. The aim is to avoid thermal bridges from the external of the home adversely effecting the internal climate through uncontrolled heating or cooling through conductivity.


thermal Insulation

Insulation acts as a barrier to heat flow and is essential for keeping your home warm in winter and cool in summer.

It can also help with weatherproofing and soundproofing. A well-insulated and well-designed home provides year-round comfort, cutting cooling and heating bills substantially, in turn, reducing greenhouse gas emissions. Climatic zoning determines the appropriate level of insulation and helps decide on the most effective type to choose. The most economical time to install insulation is during construction.


Mechanical ventilation heat recovery

Good ventilation is about achieving pristine air quality inside.

The incorporation of a mechanical ventilation unit means that you simply don’t need to rely on opening windows and doors to achieve good indoor air quality. The unit effectively recovers heat and cooling that would otherwise be wasted.



An essential part of every Passive House is an air tight building envelope.

This ensures that there are only a very limited amount of gaps and cracks within your envelope, giving you full control over your internal environment and significantly improving thermal comfort.


high performance Windows

The eyes of the house are an important piece in maintaining control over the passive nature of a house.

It’s not just the solid areas of your building envelope that need to have good levels of insulation, but your windows too. No more single glazing, but instead low-emissivity double or triple glazing with thermally broken or non-metal frames.
