High Quality High Performance

innovative, individual, inspirational - nothing else matches a Scothaus home

Scothaus is designed to meet the demands of the UK housing market and our unique island climate, as well as to exceed existing and future Building Regulations/Standards towards the zero carbon target


Only the highest quality, sustainable materials are used to manufacture the Scothaus system.  Scotframe's Code of Practice for Sustainable Construction means that:

• We actively promote the use of timber products sourced from well managed, sustainable sources.

• We maximise the benefits of timber design to reduce raw materials' waste during manufacture and construction, and to further enhance the whole-life energy efficiency of our build systems.

• We participate in continuing education and research into sustainable construction.

• We bring commercial pressure on our suppliers, wherever possible, to adopt sustainable supply chain management.


• Scothaus is manufactured using only the very best strength graded and kiln dried timber.

• Scothaus uses particle board with no added formaldehyde.

• Scotframe stores all of its structural timber under cover in a temperature controlled environment to maintain the correct moisture content.

• Scothaus components are supplied by Europe’s leading manufacturers of doors, staircases and windows.

Thermal Efficiency

The Scothaus technical team has the expertise to "thermally engineer" your house design to ensure that your home not only meets, but readily exceeds building regulations/standards.

In the Scothaus Advantage section of this website you will find animated details of the 4 wall options available to you, right up to passivhaus standard.

The Scothaus build system virtually eliminates the likelihood of interstitial condensation and so improves your home's lifespan.

The Scothaus combination of exceptional airtightness and thermally efficient fabric mean that your home emits lower levels of CO2.  The reduced heat loss means that your home will require a relatively smaller sized heating system thereby decreasing your energy costs.

Typically, owning a Scothaus home means that your annual energy costs could be reduced by 50% or more depending on the wall specification you choose.


Air leakage is the uncontrolled flow of air through gaps and cracks in the fabric of a house.  Addressing air leakage in new housing is key to reducing heat loss and associated CO2 emissions.

Air leakage should not be confused with ventilation which is the controlled flow of air into and out of your home through purpose-built ventilators required for your comfort and safety. Excess air leakage leads to unnecessary heat loss, discomfort from cold draughts and increased energy costs.

With more stringent building regulations requiring mandatory pressure tests on all newly built homes, reducing air leakage, or improving ‘airtightness’, is an increasingly important issue.  In line with Energy Saving Trust guidance, Scothaus adopts a ‘build tight – ventilate right’ policy.

Draughts and localised cold spots can cause discomfort. In extreme cases, excessive infiltration can make rooms uncomfortably cold during cooler periods. A Scothaus home is an airtight home and will significantly improve the levels of comfort you experience.  Every Scothaus home is designed to accept a Heat Recovery and Ventilation (HRV) system which provides fresh air and improved climate control, whilst saving energy by reducing heating (and cooling) requirements

Exceptional airtightness underpins the thermal performance of the Scothaus system.  The most recently constructed Scothaus home achieved an airtightness rating of less than one air change per hour - in other words a passivhaus standard of airtightness.

Acoustic Performance (Quietness)

The acoustic performance or, put simply, the quietness of your property is an important feature contributing to the enjoyment of your Scothaus home. Building regulations/standards require new homes to be built so as to reduce the levels of noise entering the property, and within the property itself: between the floors and between rooms.

Joints between elements and unwanted gaps in the building fabric are sealed as a part of the airtightness requirements. Along with the superb fabric specification of the Scothaus system, the further on-site sealing reduces sound transmission, both from outside to inside the dwelling and also between the floors and between rooms.

Scothaus offers superb acoustic performance, easily surpassing the standards required by building regulations, further enhancing the enjoyment you will get from your new home.
