We believe your home should be your safe place, your place of sanctuary. A place of rest and love, a place that makes you feel restored. Our aim is to help your building become a more comfortable place to live, through using the right materials.
Built the same way, wherever you're starting from.
For
Main Contractors
Tight schedules, direct contact with your site manager, and walls left clean and plaster-ready. That's how we work on a contractor's programme.

Built differently.
On purpose.
A small, expert team which means every job gets full attention, proper preparation, and the kind of care you only get when the people installing it actually care about the result.
01
The spray advantage
Sprayed hempcrete bonds directly to the substrate, no air gaps, no mechanical fixings, no cold bridges. It follows the natural contours of a historic wall without compromising breathability or character.
02
Sally the 3CM machine
Our French-built 3CM sprayer is one of only a handful operating in the UK. Used across France for decades, she delivers consistent installation at a pace and quality hand-casting simply can't match.
03
PassivHaus in-house
Annie is a certified PassivHaus designer. Hygrothermal assessments, U-value calculations and WUFI modelling happen inside our team, not outsourced. Technical rigour baked into every specification.
Why spray installation
No gaps.
No compromises.
Because the mix is sprayed wet, it adheres directly to the wall with zero air gap at the interface. This matters enormously for older buildings where interstitial condensation is the primary risk of any internal wall insulation.
-
Reduced condensation risk
Wet spray eliminates the air gap that drives moisture problems in retrofit IWI.
-
Complex details handled
Window reveals, curved walls, difficult junctions: the spray reaches where casting can't.
-
Faster at height
Scaffolded elevations are significantly quicker to spray, reducing your labour programme.
-
No mechanical fixings
No cold bridges, no disruption to the existing building fabric.

Founder & Technical Director
Annie
MSc Green Building & Sustainability · Certified PassivHaus Designer
Annie founded Adyta after her MSc revealed the gap between how the industry talks about breathable construction and how it actually delivers it. She manages technical specifications, hygrothermal assessments, PassivHaus consultancy, and client relationships on every project.
Site Director & Master Installer
Jack
Natural Builder · 3CM Spray Specialist
Jack leads every installation. He has an instinctive feel for how hempcrete behaves in the machine, against the wall, and in the building over time. The quality of Adyta's work on site is down to his standards and his refusal to cut corners.
The 3CM Sprayer
Sally
French-built. Proven across Europe for 30 years. One of a handful operating in the UK.
The 3CM is the professional-grade hempcrete spray machine used throughout France and Europe, where hemp-lime construction has a multi-decade track record. Sally is what makes consistent, fast, detail-perfect spray installation possible and her friend Harry the hemp box keeps her fed. Our team understands these machines deeply: how they perform in different conditions, how to calibrate the mix, how to achieve a consistent installation every time.
