Stockton House, a completed high-performance coastal home by Blencowe Design

Performance-led

Airtightness, insulation continuity, thermal bridge-aware detailing and moisture control are considered early, not patched on later.

Documentation-focused

Clear drawings and construction logic for builders, consultants and clients who value well-resolved decisions.

Regionally grounded

Newcastle, Lake Macquarie, Hunter Valley, Central Coast and selected NSW projects.

Design approach

Design starts with how the home needs to feel, function and perform.

Good residential design is not only how a home looks when finished — it's how the envelope manages water, heat, air movement and construction tolerances for decades. Blencowe Design brings design, documentation and high-performance detailing together into one calm, practical process.

Based in NSW, Blencowe Design works with selected residential clients across Newcastle, Lake Macquarie, the Hunter Valley, the Central Coast and wider New South Wales.
