Passive House Vs EnerPHit

What does it all actually mean?

Passive House is a rigorous, voluntary standard for energy efficiency in a building. Resulting in ultra-low energy buildings that require little energy for heating or cooling, creating a highly comfortable and sustainable living environment.

Passive house design can save you up to 90% in energy compared to a standard building.

Passive House

EnerPHit is a certification standard for the energy retrofit of existing buildings, ensuring they meet high energy efficiency and comfort levels similar to new Passive House constructions, making older structures more sustainable and comfortable to live in.

ENerPHit design can save you up to 70% in energy compared to a standard building.


Comfort without cost:

Think of insulation as your home's super-cozy, energy-saving blanket. We're not just stuffing walls with fluff; we're strategically wrapping your place to keep it toasty.


A view without the draft: 

Our triple-glazed windows are the unsung heroes of energy efficiency. They're engineered to maintain your home's warmth or coolness, acting as a barrier against energy loss.


Keep your heat where it belongs: Our approach ensures your home is perfectly sealed. Every gap is meticulously closed to lock in warmth, reducing your energy consumption significantly. 


Banishing mould and damp:

These pesky intruders can ruin your cozy vibe. We outsmart them with design a so clever, it eliminates cold spots, ensuring your insulation's hard work doesn’t go to waste.


A breath of fresh air:

With our homes sealed tight, we introduce our secret weapon: Heat Recovery. It's like giving your house lungs, constantly refreshing the air without losing heat. 



But what does it mean for you?
It means you get to save money on your energy costs.

Why Arkhi Zero?

Your ambition is our driving force. We will support you on your journey and create beautiful spaces that align perfectly with your lifestyle and desires.


You can truly be rid of those high running costs with our help. We can put you in control of how your building functions. It's peace of mind, with the proven building performance data behind it.


We'd love to talk to you about how you can invest in your property instead of giving your money away to the energy companies. And crucially, see a proven return on your investment

Who said eco-friendly cant be sexy? 

Take a look at the project's we have worked on in collaboration with our clients.

The Roost

Arkhi  transformed a North Staffordshire stable into a pioneering eco-residence blending modern design with nature. Incorporating eco-friendly elements and wildlife support, the project navigated strict regulations to feature large windows, a living roof, and rainwater ponds, epitomising sustainable living in the Moorlands.

Brookmere Barns

For a retired couple seeking to downsize, we designed a home that merges a masonry farmhouse with a steel and concrete barn in an L shape, surrounding a traditional courtyard. This design, accommodates up to 20 guests, honouring its heritage while incorporating modern sustainability, featuring a glazed link for energy efficiency and reflecting the couple's sociable lifestyle.

What Our Clients Say

“Unexpectedly low energy consumption is a result of the SIPs construction, ASHP and UFH. The energy performance of the completed building exceeds that predicted by the SAP studies..”

Brookmere Barns

“It was their genuine passion, energy and professionalism that really sold us, we made our decision within the first ten minutes of meeting them, we just knew that we had found the company for our project.”

Cressington Hall

"The resulting design is everything we could have hoped for and more - constructed on time, and on budget, despite the pandemic, Suez canal blockage and Brexit! We now have a light, warm, super energy-efficient house, which has also increased wildlife habitat and looks beautiful. Everything a new home should be."

The Roost

Welcome to the heart of Arkhi Zero—our team. With a shared passion for pushing the boundaries of architecture, we're not just designing homes; we're crafting a better way of living.
