The 3 decisions that shape your custom architectural home in Angle Vale
Architect + builder vs design-and-construct
Traditional route is architect designs, tender to builders, builder builds. Design-and-construct puts one company in charge of both. Each has different cost and control trade-offs.
Fixed price vs cost-plus
Most project builds are fixed-price. Custom builds are sometimes cost-plus, meaning the builder is paid a margin on actual costs. This shifts the price risk to you.
Documentation depth
The single biggest driver of custom-build outcome is drawing detail. A 40-page set of drawings and specs gets a tighter quote than a 20-page set.
Custom Architectural Home FAQs for Angle Vale
How much more does custom cost than project?▾
Rule of thumb is 20 to 50% more per square metre for custom compared with a project-builder home of the same finish. The gap widens with brief complexity.
Do I need an architect for a custom home?▾
You need either an architect or a qualified building designer. Both can deliver design-and-documentation. Architects are formally registered; building designers vary in scope of practice.
What is the difference between architect and building designer?▾
Architects are formally registered under the Architects Act and carry PI insurance requirements. Building designers are less regulated but many are highly experienced. The right one is the one whose portfolio matches your brief.
How do I control the cost on a custom build?▾
Freeze the brief early, keep the drawing set detailed, and get tender pricing from multiple builders. Cost blows out when the brief keeps changing during construction.
Can I use a project builder for a custom design?▾
Some project builders offer semi-custom variations of their standard plans. True custom design usually needs a custom-focused builder or design-and-construct firm.
