Dutta.ai is a hybrid, AI-powered site assessment engine for Victorian planning schemes, supervised by Swarup Dutta, a Melbourne-based Registered Planner, B.Arch, Associate RAIA, with 250+ permits managed across Victoria.

​

Swarup is a subdivision specialist and land development consultant, with expertise in town planning, concept design documentation, and dual occupancy feasibility.

If you are considering a backyard subdivision, corner lot development, vacant block redevelopment, or dual occupancy project, the first step is to understand whether your land has planning potential and what constraints may apply. Victorian guidance confirms that two-lot subdivision usually requires a planning permit, and site-specific controls such as setbacks, garden area, amenity, overlays, and title restrictions can affect the outcome.

Key considerations.

​

Before you spend money on drawings or lodging an application, we review the main feasibility drivers that affect whether a site can proceed. These include planning overlays, restrictive covenants, Section 173 agreements, title conditions, access width, services, vegetation, easements, and any cultural heritage triggers.

​

For backyard subdivision, tandem dual occupancy, the available side access and site shape are critical, because driveway width, boundary alignment, and service connections all affect design yield and council compliance. For corner lots and vacant blocks, orientation, overshadowing, street frontage, and subdivision layout can significantly improve development outcomes.

If the site stacks up, Dutta.ai helps convert preliminary site information into a clearer planning pathway, so you can make informed decisions earlier. Faster approval pathways now exist for some eligible two-home and subdivision proposals in Victoria, but every site still needs proper planning assessment and design testing.

​

Development types

​

Tandem dual occupancy

Best suited to sites with strong side access, where one dwelling sits behind the existing home. A practical guide is whether a compliant driveway can be achieved to the rear, along with adequate private open space and service connections.

​

Vacant lot development
Suitable where an existing dwelling is removed and two or more new units are built. North-facing or side-facing living areas can help improve solar access and reduce overshadowing impacts.

Corner lot subdivision
Often ideal for multiple street-facing dwellings. Corner sites can improve layout efficiency, vehicle access, and street presentation.

​

Duplex dual occupancy
Useful on wider sites where two dwellings can be designed with shared or independent walls. This can deliver larger footprints and stronger resale appeal where zoning and site conditions support it.

How we work.

​

Provide your preliminary site details, including the Section 32, title information, covenant details, vegetation, street features, and any known site constraints. We then test the site against Victorian planning considerations and identify whether the project is likely to proceed.

​

If the site is viable, our planner-supervised process supports AI-assisted feasibility testing, design direction, planning reports, and council lodgement. After approval, we can also prepare building permit construction drawings ready for your builder and lender.

​

The result is a faster and more structured way to move from address to intelligence, with clearer guidance on site yield, compliance, and development risk.
