Start with a well-sized home, thoughtful orientation, effective shading and a durable, well-insulated building envelope. Coordinate ventilation, glazing and efficient services, then assess options such as solar generation against your site, priorities and the investment you want to make in a comfortable, durable home.

Make the building work well first

Good design begins with how much space is needed and how it is arranged. A compact, adaptable layout can reduce the materials needed while improving everyday use. Place rooms to make sensible use of daylight and outlook, and consider shading as part of the design. More glazing is not automatically better: its orientation and specification affect both comfort and energy use.

Coordinate comfort measures

Insulation, glazing, airtightness and ventilation should be considered together. Improving one element without considering the others can leave opportunities unresolved. Ask how fresh air, moisture extraction, summer temperatures and winter comfort will be addressed. The appropriate solution depends on the climate, exposure, occupancy and whether the project is a new home or an alteration.

Choose materials for their whole life

Consider durability, maintenance, repairability and the amount of material required. Retaining suitable parts of an existing home can be valuable, but it needs to be balanced against condition and the proposed use. Ask for evidence supporting environmental claims rather than assuming that a material is sustainable because of its label or appearance.

Add technology where it makes sense

Efficient hot water, heating and appliances can complement a well-resolved building. Solar generation should be assessed against roof conditions and household demand. Agree priorities early so your investment supports everyday comfort, durable materials and the long-term needs of your household. Modal integrates these discussions into new home design and renovations, with specialist input or performance assessment where appropriate.
