Episode 11: Custom Homes: Inside SHM’s Design–Build Process (Concept Design to Contract Signing)

What does a design–build journey actually look like—from first enquiry to a signed building contract? In this episode, builder Simon Clark walks through Sustainable Homes Melbourne’s proven process, step by step: Discovery Session at the Fitzroy studio → Design Kickoff on site (with re-establishment & feature survey) → a Feasibility Plan with project-specific sqm guidance → Concept Design with iterative reviews → a detailed Concept Estimate and specification → Planning management (if required) → full Design Documentation (engineering, energy assessment, soil tests, interiors) → Contract Estimate and contract signing. Along the way, Simon explains SHM’s four core standards—140 mm stud walls (R4), thermally broken timber/UPVC windows, Pro Clima vapour-permeable membranes, and HRV (heat-recovery ventilation)—and how they lift comfort, durability, and performance for Melbourne homes. You’ll learn:The complete SHM timeline: discovery, site kickoff, feasibility, concept, estimating, planning/docs, contractWhy early estimating discipline prevents decision fatigue and keeps scope aligned with expectationsHow project-specific sqm rates differ by site type, location and finish levelWhat’s included in documentation: structural & (where needed) civil engineering, energy, soil tests, interiors, and who appoints the building surveyorThe performance basics every custom home should have: R4 walls, airtight/water-managed envelopes, HRV, thermally broken windowsWho it’s for: Melbourne homeowners planning a custom renovation or new build, plus architects/designers who want a clear, cost-literate path from concept to contract.If you'd like to know more, please reach out to Sustainable Homes Melbourne or call us on 1800 683 697.
