Site review
We assess frontage, zoning, slope, services, planning controls, value and likely duplex yield.
One Site,
Two Homes.
Shared Value.
The opportunity
01Your land may be worth more than the home currently sitting on it.
Addison focuses on carefully selected duplex sites in Sydney. If your property is suitable, you may be able to participate in the value created by a duplex rather than selling the property. You contribute the land. Addison manages and funds the development, including feasibility, design, approvals, finance and construction.
The proposed arrangement explains what each side contributes and how the two residences will be divided under an agreed legal structure. It also sets out the proposed home allocation and key conditions, so you can consider the opportunity before deciding whether to proceed.
Under an agreed arrangement, the homeowner may receive a brand-new home while Addison coordinates the development. Every proposal remains subject to site feasibility, valuation, finance, planning controls, tax and legal advice.

Stay in the area you love while working with a development partner.
For a suitable property, a duplex partnership may offer a way to take part in the site's development potential without managing every step alone.
Addison coordinates feasibility, design, approvals, finance and construction. The proposed responsibilities, home allocation and key conditions are discussed upfront, giving homeowners a clearer picture of the pathway before deciding whether to proceed.

Our process
02From first conversation to two completed homes.
Under our agreed partnership structure, we cover the development costs and provide a complete finishes schedule before construction, so owners can see how the completed home will come together. Every arrangement remains subject to site feasibility, valuation, finance, planning controls, tax and legal advice. Our role is to make the pathway clear.
Partnership proposal
You receive an indicative design, residential model, responsibilities, proposed home allocation and key conditions. The proposal records that, under the agreed structure, we cover the development costs.
Legal structure
Independent solicitors document title, security, funding, approvals, ownership, risk and exit arrangements.
Design & approval
Architects, consultants and certifiers progress the design through DA, CDC or other required approvals. Before construction, we provide a complete finishes schedule so you can see how the completed home will come together.
Construction
We coordinate procurement, construction, quality control, programme and regular owner updates. Owners choose their preferred colour palette, tiles, tapware and joinery finishes, with selections documented in the final specification.
Completion & division
The homes are completed, certified and transferred or retained in accordance with the agreed structure.
