sustainable design

Our approach is to build for the future, utilising the latest sustainable materials and design techniques.

Creating energy efficient homes which are sustainable and cost effective. Performing throughout our hot summers and colder winter months.  Ensuring healthy comfortable homes, which contribute to reducing our carbon footprint.

Our project include: Passive House Design & 9.5 Star Homes.

Several concept’s based on our initial guidance were delivered along with practical design advice in accordance with the project brief and budget. The interior design and colour pallet selection process was simple and professionally managed to ensure a quality product.

The support provided through the design, approval and construction cannot be faulted and we have no hesitation in providing a reference to future clients.

Seamus was recommended to assist when I was looking at Passivhaus construction for a new home in Mount Claremont. Seamus pulled together the design and my thoughts to build a fully insulated reverse brick double glazed house, gaining a 9 star energy rating.

I am again very thankful to have Seamus’ experience, patience and most of all perseverance. 

Over a short-time; Seamus helped us clarify in our minds what we really wanted from our renovation & addition. In doing so; any issues or problems were address with a clear solution. With that, Seamus was able to go do his magic, presenting an overall design solution to our detailed brief. 

Seamus’ input and advice has been invaluable over the course of the project. We would highly recommend Seamus.

Seamus ensured the extension was built to a very high energy efficient standard in which we achieved a 9.5 star rating. Our final design / tender package was very detailed with a great package sent to tender, and had very little change throughout construction. 
We enjoyed working with Seamus &  would highly recommend.
