One structural system behind all five: a load-bearing timber frame packed with mechanically compressed straw, closed and finished the way the building demands.
Custom Homes
We take a plot and a brief and return a house that ends the year having made more energy than it used. The walls are 300–400 mm of compressed straw in a double timber frame — passive-house-grade fabric before a single panel of solar is fitted. Design, engineering, fabrication and assembly are ours; the specification is yours.
Renovations + Additions
Straw panels fix to the outside of a solid masonry wall as an over-cladding, taking a leaky building to passive-house-grade fabric without losing a square metre of floor area. Additions work the same way — a straw-panel storey is light enough that existing foundations usually need no underpinning, and the house stays occupied through most of the work.
Special Projects
Small buildings are where fabric quality is usually abandoned — a thin stud wall and a room that is unusable in February. Ours are the same wall as the main house. And for people who want to finish their own home, the Shell package delivers the structure, membrane, wood-fibre and render signed off and weathertight, with the roof left ready for photovoltaics.
Fabric & Energy Care
A net-positive house has two things worth watching: the render that keeps water off the straw, and the energy system that makes the surplus. We inspect the render and the rainscreen, service the inverter and check battery health, clean the array, and send you the year's production against what the house actually used — so the surplus is a measured number rather than a claim we made once.
Commercial
Commercial work is where the certificates stop being a nicety. Rendered compressed-straw assemblies are classified for reaction and resistance to fire under EN 13501, designed to the full Eurocode suite including seismic, and verified against the national energy regulation. Diagonal timber bracing inside the panels carries racking load across long elevations.
In detail
How straw is compressed into a load-bearing frame, the six steps from press to move-in, and the energy system that makes the surplus.
ISO 9001, ETA + CE marking, Passive House component certification, EN 13501 fire classification, EPD — and the shake-table research behind the seismic claims.
