About me

Mark Borthwick

I'm passionate about architectural technology, always seeking new innovations to improve on efficiency and sustainability in houses, new and old.

I love a challenge, seeking alternative solutions for clients they haven’t thought of before, looking for the best approach to every project and budget.  

So, what is an Architectural Technologist? In summary, an Architectural Technologist combines logical technology elements with the aesthetics of architecture, leading the design of a project from concept to realisation.

What is a Passive House Designer? Again, in summary, a Passive House Designer creates environmentally conscious, comfortable, and cost-effective buildings that harmonise with their surroundings while minimising energy consumption. 

Put plainly, my aim is to provide good quality design to ensure occupier comfort is at its peak, and that your home flows naturally and is well balanced.  It's time to say goodbye to that old drafty house and hello to your perfect home!

"We would 100% recommend Mark. We finally found someone who gave us the advice and reassurance we needed (after years of planning & architect pain!). He is very calm, knowledgeable and professional and helped changed our view on our house renovation.
He helped us replan our house so it flowed better downstairs, investigated more environmentally ways to heat our house and he expertly managed the tender process of finding the right builder with great attention to detail. We will definitely call upon his help again if needed.

It's been a hectic week on the Shiplake build. 9,000m of individual reinforcement bars, 18,000 ties and a full day of concrete lorries to cast the slab, finishing just after 6pm!  Coupled with the Jackon Atlas insulated panels, it provides a thermal bridge free raft
