Before you spend money on plans, answer these three questions.
Considering a duplex or small residential development? Start by understanding what your site could accommodate, the likely total investment and whether the outcome makes sense for you.
What could I build?
Understand the planning controls, site constraints and development options worth exploring for your property.
What is it likely to cost?
Get an indicative view of construction and the wider project costs—including consultants, approvals, site works and holding costs.
Does the project make sense?
Compare the likely costs and completed values against your goals, whether you intend to sell, retain or live in one of the homes.
Our feasibility study brings these findings together, helping you decide whether to proceed, adjust the brief or pause before committing further.
Assessed through a developer-builder lens
Vector Homes brings first-hand experience developing and building residential projects in Melbourne’s eastern and south eastern suburbs.
That experience informs how we assess your property - from dwelling proportions and construction methods to site access, specification and the relationship between build cost and completed value.
We consider how the project could be delivered, what may complicate it and whether the proposed product makes sense for the site.
If you choose to proceed, we can also help coordinate the next stages of design, planning and construction, carrying the feasibility findings into the developing project brief.
