Retrofit,
measured.
We design and build whole-house retrofits across Oxfordshire — insulation, windows, ventilation and heating as one programme, one contract, one accountable company. Then we publish what the building actually achieved.

The work
All projectsWho we work for
Four kinds of client, one method: understand the building, fix the fabric first, publish the result.

Homeowners
A warmer, quieter, healthier house — one programme, one contract, one point of accountability from survey to handover.
Landlords
EPC C by 2030 without guesswork — fabric-first improvement plans, costed and phased around your tenancies.

Architects & specifiers
A delivery contractor fluent in building physics — U-values, airtightness, moisture-safe junctions, honest programmes.
Period & listed homes
Breathable materials — wood fibre, cork and lime — for houses that were built to breathe, in conservation areas and beyond.
From the knowledge hub
All guidesWhole-house retrofit: the complete guide
What it involves, what order to do it in, and how a fabric-first programme actually runs — from first survey to the final EPC.
EPC C by 2030: a landlord's working plan
What the proposed deadline means for rented homes in Oxfordshire — and how to phase fabric improvements around tenancies.
Wood fibre, cork and lime: how breathable materials work
Why solid-wall houses need insulation that handles moisture — and where each material belongs in the build-up.
Every retrofit starts with a free survey.
A senior surveyor walks the house, takes the measurements, and tells you honestly what it needs — and in what order. Written summary either way.
