Meet the Team

Think of us as a collection of quirky, unconventional ingredients. We’re a mix of curiosity and worldly experience, with a sprinkle of youth and a dash of determination. Blend it all together, top it off with a cherry of uncompromising vision to leave the world a better place, and you’ve got yourself a Base Haus milkshake. There’s plenty of fun froth on top, but the real good stuff is at the bottom where the chocolate sauce is - mmm... deeply satisfying.

Still with us?
In simple terms, we’re here to do good, not just talk about it. You won’t find any greenwashing or diluted outcomes here - just a relentless drive to do the right thing and make a real difference.

Through our first-hand experience in working on PassivHaus builds we quickly realised the strength and untapped potential of the PassivHaus concept. We now exist to help others achieve PassivHaus in residential and commercial buildings by harnessing the power of automation and technology. Removing the barriers of manual modelling and simplifying the certification process, we are working to achieve our vision of Making Passiv Massiv.

Ben Sinclair

Founder // The daydreamer and blue-sky visionary

Ben tackles subjects he initially knows little about with a fresh perspective that others might miss. He thoroughly researches from every angle, investigating new ways to achieve ideal solutions by combining existing and emerging frameworks. A visionary leader with hands-on design and construction experience, Ben’s innovative mindset drives Base Haus’ mission of energy efficient outcomes accessible to everyone. Most importantly, he knows he can’t do it without the team. This people-first approach puts culture at the centre of everything we do. It’s got to be fun, otherwise what’s the point?

Luke Pearce

Computational Designer // The diamond in the rough
Every day is a surprise with Luke. He defies the saying “you can’t teach an old dog new tricks” because, well, he’s not old yet. As Head of Computational Design, Thermal Envelope Analysis, and all things automated, Luke makes the daydreams technically possible. Expert in thermal envelope analysis and automation, Luke ensures the technical viability of ambitious designs. With way too much time spent talking about food, cooking,and kitchen gadgets - balanced with a healthy interest in exercise - Luke is worth his weight in gold carbon (reduction).

David Plumb

Lead Building Designer // The OG

Part of the original team, David was there amongst the action when we designed and built CORNERBLOCK. With a natural flair for design, everything David touches has a unique flavour. In charge of all things architectural, David brings the experience and expertise that balances Luke’s youth and Ben’s aspirations. After a few years working in large architecture firms post-CORNERBLOCK, David’s desire to make a bigger impact on society and those around him brought us back together, refreshed and ready for new challenges. We couldn’t do what we’re doing without him. With extensive architectural experience, David’s creativity and professionalism ensure projects meet both aesthetic and performance goals.

Sarah Chan

Software Engineer // The enigma

Officially our in-house IT consultant, Sarah’s true talents lie in building bridges between Ben’s sky-high ideas, Luke’s nuts-and-bolts approach, and David’s architectural vision and compliance expertise. Sarah bridges the gap between technology, design and implementation, ensuring seamless integration of solutions. Fuelled by good food, and armed with an insane eye for detail, she combines determination and intelligence into a daily superpower.

Markella Voulcaris

Operations // The glue

In the 80s or 90s, Markella’s role would have been “office manager,” but this is the 21st century! So let’s try ISO implementation officer, payroll, HR, accounts, health and safety officer,chairperson, carbon reduction strategist, office manager, charity and volunteer coordinator... you get the idea! The realist of the group, she’s the one who makes deadlines happen, ensuring smooth operations across the team. With a background in law, psychology and education, Markella shares the vision of leaving the world a better place, and her support in achieving that is priceless.
