About
An intentionally small practice with a deep technical backbone.
Blencowe Design is led by Craig Blencowe, bringing more than 20 years of experience across residential design, documentation, structural drafting and construction-aware detailing.
Practice
Small by design, detailed by nature.
Craig’s background combines residential building design with a strong understanding of documentation, structural drafting and how construction decisions actually play out on site. That mix gives Blencowe Design a practical edge: design intent is supported by buildable drawings and careful technical thinking.
The practice is deliberately selective. Rather than trying to service every type of residential project, Blencowe Design focuses on homes where comfort, durability, airtightness, insulation, thermal bridges, moisture control and documentation quality genuinely matter.
Craig has experience designing Passivhaus homes using PHPP, alongside broader high-performance residential work where Passivhaus thinking informs the envelope, orientation, services strategy and construction detailing.
Residential design
Custom homes, major alterations, additions and selected compact infill projects where the brief deserves more than a standard response.
Technical documentation
Clear drawing sets shaped around approvals, consultant coordination, construction sequencing and builder understanding.
Performance mindset
Comfort, airtightness, thermal bridge-aware detailing, insulation continuity and weather-tight construction considered from early design.
