Passivhaus doesn’t have to be complicated. And it certainly shouldn’t be intimidating.
Yesterday we were on site in Worcester, visiting this impressive three-storey home which we designed to meet the Passivhaus Classic standard. Our clients are experienced builders, so they understand the importance of getting the details right. But what’s particularly great about this project is how enthusiastically they’ve embraced the combination of Passivhaus performance and contemporary design. The result will be a home that isn’t just striking to look at, but comfortable,

Planning. Budget. Overheating. Three of the biggest worries for anyone thinking about building their own home.
We hear them all the time. “Will we get planning permission?” “Will our new home overheat?” “Can we actually afford to build what we want?” And while every self-build project is unique, these are questions that should be addressed from the outset. At Habitat+ Architects, we combine creative architectural design with practical, real-world experience to tackle these challenges from the very beginning. We look carefully at the opportunities and constraints of your site — from pl

Why keep your architect involved during the build?
At Habitat+ Architects, we believe our role shouldn’t end when the drawings are issued and a contractor is appointed. Stage 5 (the build) is where the design becomes reality — and, in our experience, it is also where having the original design team involved can add significant value to a client. We’ve seen first-hand how our involvement during construction can protect both the building and the client’s investment. It’s easy to recall examples where contractors have made mist

A Passivhome
We’re delighted to share a few photographs of our completed Knossington Passivhaus project in Rutland, which was completed just before Christmas last year. It’s wonderful to see the garden now taking shape – not an easy year to do this in - and to see the house beginning to feel like a home rather than a building site. The replacement dwelling was a planning success, with this contemporary design securing planning permission at the first attempt. We worked closely with the

A challenging undercurrent
We are excited to see our Anchorage Passivhaus project featured in its second publication of the summer: The Self Builder Magazine. “A Challenging Undercurrent” is the story of an ambitious self-build that proved to be every bit as challenging as its riverside setting suggests. Overlooking the River Avon, this striking cantilevered home was designed for experienced self-builders Frank and Kerry, who set out to create a contemporary, highly sustainable house on a steep and c

Pushing the boundaries
We're delighted to see Anchorage Passivhaus featured over an eight-page spread in the July 2026 edition of Build It magazine. The article explores Kerry and Frank's remarkable journey and their vision for their final self-build home that would challenge conventional perceptions of Passivhaus design. The result is a Certified Passivhaus that combines outstanding energy performance with a bold, contemporary architectural expression, set within a sensitive riverside Conservation

Overcoming levels, delivering performance.
Progress continues on our latest Passivhaus self-build project in Purley, with foundations and drainage now complete and the house about to emerge from the ground. The significant level change from front to back has created some interesting design and detailing challenges. We’ve enjoyed balancing these constraints while maintaining Passivhaus performance standards and keeping a close eye on budget, which is standard for us. Today’s heatwave site visit was intense, and we cert

Low-energy homes with life-changing impact
At Gatehouse Road, Aylesbury, low-energy sustainable architecture is doing far more than providing shelter - it is helping create stability, dignity and healthier futures for people experiencing homelessness. Working alongside forward-thinking housing association Fairhive Homes, this recently-completed project delivered seven Passivhaus-standard homes designed specifically to support vulnerable occupants through exceptional comfort, low running costs and healthier indoor envi

Five ways to keep building costs under control without compromising your design
Planning a building project in the UK, whether it’s a building transformation, low-energy building or a Passivhaus home, often raises one key question: how do you control construction costs without diluting the design? At Habitat+ Architects Ltd, we believe thoughtful architecture, sustainable design and financial clarity should work together. With careful planning and the right professional guidance, it’s possible to manage your build budget while still achieving a high-qual

The benefit of energy independence
For self-builders, energy independence is no longer a ‘nice to have’ but instead is becoming essential. Recent global events have shown just how exposed our homes are to political events outside of our control: the ongoing conflict in the middle east has already driven sharp increases in oil and gas prices, with knock-on effects for UK households through rising energy bills. At Habitat+ Architects, we see Passivhaus as a direct response to this uncertainty. The approach is s

No design changes needed
What do these three buildings have in common? They were all granted planning approval without any requirement for design changes, despite each being located in a highly sensitive planning context. Knossington Passivhaus (Conservation Area), The Paddock House (outside a settlement boundary and adjacent to a Grade II listed building), and the Performing Arts and Dining Building at Lingfield College (Green Belt) each faced very different constraints. Yet all three secured cons

Exploring a Passivhaus self build but worried about compromising design elegance?
When people think of Passivhaus design, the stereotype is often a simple, box-like shape focused purely on efficiency. But Passivhaus doesn’t mean dull — it means smarter, more thoughtful design that works for you and your site. A perfect case in point is Anchorage Passivhaus in Wyre Piddle. This Certified Passivhaus shows that energy-efficient homes can be dynamic, expressive and beautifully tailored to their surroundings. Set on a steep riverside plot in a Conservation Area

First impressions count
In today’s challenging financial climate, effective marketing matters more than ever. We have worked with many schools to reimagine their campuses, helping them present their environments at their very best and create strong, confident first impressions. At Lingfield College, this meant transforming a brutal, monolithic 1990s arrival experience into a warm and inspiring journey - one that truly embodies and reflects the pastoral care for which the School is so well known.
