PROJECT OVERVIEW
The Retreat is a PAS 2035 Pathway B, fabric-first retrofit across five 1970s terraced bungalows designed with accessibility in mind. We provided full coordination, design and statutory interface (planning & CDM).
HOW WE GOT STARTED
We began with a digital-first survey approach: LiDAR scanning and drone surveys to model roof geometries, access, and site constraints, supported by cavity wall assessments and borescope investigations. This informed a PAS 2035-compliant strategy tailored to the terrace configuration and construction, streamlining design coordination and reducing repeat site visits.
CHALLENGES & SOLUTIONS
Asbestos management:
Early investigations identified asbestos-containing materials in soffit panels and T+G boards. We integrated licensed removal into the CDM 2015 health and safety plan and coordinated sequencing to avoid programme disruption.
Ecology and planning compliance:
An initial client commissioned bat survey did not meet planning requirements and works were paused after roofing commenced. We engaged an ecologist and advised suspension of activity pending a dusk emergence survey, mitigating legislative risk and preventing further delay.
Cavity condition and structural integrity:
Failed insulation and localised wall tie defects were addressed through cavity extraction, new cavity fill, and wall tie replacement as required, ensuring a sound substrate for EWI.
Integration and detailing:
Associated EWI (external wall insulation) works included roof extensions/overhangs, coordination of RWPs, SVPs, fixtures, fence/wall connections, and door undercuts to support balanced ventilation. Roof insulation was topped up, alongside positive input ventilation (PIV) & solar PVs.
FINAL OUTCOME
The project has delivered significant improvements in comfort, running costs, and carbon, with positive client feedback on technical rigour and risk management, particularly around asbestos, ecology, and statutory compliance.
The Retreat demonstrates how coordinated, fabric-first retrofit, delivered under PAS 2035 with clear sequencing and evidence led design, can unlock substantial performance gains across small, accessible bungalow typologies.
"We experienced first-class service from a great team, whose experience and determination ensured our projects were completed and lodged efficiently.
Their dedication and expertise truly made a difference in achieving successful outcomes, and it was a pleasure working with such a committed team, and I look forward to continuing this in the future."
