Do both duplex dwellings need to have the same floor plan?
No. The dwellings may be mirrored, similar or individually designed.Different layouts may be appropriate where one dwelling is intended for the owner and the other for extended family, rental or sale. The arrangement must still respond to the site, planning requirements, structure and overall architectural composition.
Can a duplex be designed for two related families?
Yes. A duplex can be designed for parents and adult children, siblings or other related households seeking proximity while retaining separate living arrangements.The design can consider accessibility, privacy, shared outdoor areas, complementary room arrangements and the potential for connection between the homes where permitted and appropriate.
Can the two dwellings have different sizes and finishes?
Potentially. The size, accommodation and level of finish can differ where the site, planning controls, structure and client objectives allow.These differences should be identified early because they can affect the building form, documentation, service arrangements and construction pricing.
Can a duplex be built on a sloping site?
Potentially, but slope can significantly affect excavation, retaining structures, driveway gradients, drainage, floor levels, access and construction cost.A sloping site may also create opportunities for split-level planning, views, separate entries or basement parking. The appropriate response depends on the property and engineering requirements.
Can each duplex dwelling have its own street appearance?
Yes. Each home can have an individual entry and identity while remaining part of one coordinated architectural composition.The degree of visual difference depends on the intended character, planning context, site width and overall design approach.
Can the duplex dwellings be separately sold?
This depends on the approval, subdivision arrangements, title structure and other legal and authority requirements applicable to the project.Clients should obtain appropriate planning, surveying, legal, taxation and financial advice before relying on a particular ownership or sale strategy.
