A sustainability expert answers your design and build questions

AP: What are ways people renovating an older home can incorporate sustainability?

CK: Yes, they can. There is no silver bullet for everyone, because every old home comes with different criteria, however the most important investment that you can do is:

1) Heating & ventilation

Why? If you get the moisture out of the house the air is easier to heat and it's cheaper to maintain.

2) Windows & insulation

Why? You want to make your home as airtight as possible. Make sure you insulate your home with breathable products, so that moisture can still escape to the outside.

3) Thermal break & high performance membrane

If you need to take your cladding off, that is the ideal scenario, because you then have access from the outside to insulate your cavity. The ideal product to eliminate thermal bridging is to use a wood fibre board on the outside frame and cover it with a high performance membrane, then add cavity batten and put the cladding back on. Again, it's different from project to project, and this is only a general tip.

AP: What's the biggest mistake homeowners make when trying to incorporate sustainable design into their project?

CK: If you don't ask the right questions, or whether the professional is familiar with a range of products, you may miss out on a great opportunity for your project. Some professionals are only focused on one product or one supplier, so ask for alternative options, because there are plenty of them. I hear clients say often, "I wished I knew that before."

AP: Does sustainability mean homeowners have to compromise on aesthetics?

CK: Not at all, it's the opposite! 

How can sustainability consultants help homeowners embarking on a project?

A consultant can help them through the process, to make informed decisions for their project. We are there to help them to compare products' pros and cons, product performance and to help them find the right design and build team, usually saving them money already in the design phase so that they don't go over budget.

Tell us about any cool projects you have in the pipeline? Our team is working with an award-winning architect in the UK named:Koto Design. They have a unique way of expressing themselves through their work. Simplicity and minimalist designs with a mixture of Scandinavian and Japanese touches, it reflects their message to reduce the footprint and look after the environment by using sustainable products. Our values are very much aligned with the team and that was the reason for the decision we have made to collaborate.
