Building design for new homes, additions, granny flats and everything in between.
Blencowe Design is a building designer working across Newcastle, Lake Macquarie, the Hunter Valley and the Central Coast — house plans, home extension plans and construction documentation for homeowners, investors, developers and builders.
What we design
Every kind of work, one standard of drawing.
Searching for a draftsman or building designer in Newcastle or Lake Macquarie? Blencowe Design prepares complete house plans and construction documentation — with the design thinking built in.
New homes
Custom house plans shaped around your site, brief and budget — from first sketches and feasibility through to construction documentation. See recent homes.
Alterations, additions and smaller jobs
Home extension plans and whole-house reworks — and the smaller jobs too: carports, decks, garages and verandahs. They're quick to document properly, and they're genuinely welcome.
Granny flats, duplexes and dual occupancy
Secondary dwellings, dual occupancy and small multi-dwelling development, drawing on twenty years of exactly this work. Read more for developers and investors.
Knockdown rebuilds
When replacing the house makes more sense than reworking it — a realistic read on the site, then design and documentation for a clean rebuild.
Designing a great home
Performance and Passivhaus: orientation, glazing, insulation and airtightness fundamentals, all the way up to full certification. How far do you want to go?
Documentation
Clear, builder-ready drawing sets for approvals, consultant coordination and construction — the same standard on every job, large or small.
How the practice works
Blencowe Design is a one-designer practice: you deal directly with Craig from first conversation to final drawings, whether the job is a carport or a certified Passivhaus build.
Efficient, repeatable documentation keeps smaller jobs quick and multi-dwelling work commercially sensible — and every set of drawings gets the same care.
Documentation you can build from
Drawing sets prepared for approvals, consultant coordination and construction-stage decisions — documentation that respects how buildings actually go together, reducing ambiguity around sequencing, structure and envelope work.
Clear drawings save money on site. That's true on every project, at every scale.
