An existing section may offer room for another home, but a good infill project needs more than a spare patch of land. Modal helps you explore a second dwelling that respects the original house, makes efficient use of the site and offers a comfortable place to live. We work with owners considering family accommodation, a rental home or a broader property plan.

Look at the whole property first
We review access, boundaries, terrain, services and the relationship between existing and proposed buildings. Planning requirements and site constraints affect what can be achieved. An early site assessment and concept study can help you decide whether to progress to detailed design.
“We were very happy with their performance on our house extension & infill home projects.”

Protect the quality of both homes
Privacy, sunlight, outdoor space and a clear sense of entry matter for every household. We explore how the new dwelling sits on the site and how its layout can use the available footprint well. Thoughtful positioning can be as important as the number of rooms.

Coordinate the approvals and infrastructure
Infill projects may need input from planners, surveyors and engineers, alongside architectural design. Servicing and access can have significant implications, so we consider them early. We help clarify the design and consent scope; subdivision, if intended, needs its own assessment.
“Modal Architecture excels at navigating conversations where planning constraints and design aspirations intersect.”

Design with delivery in mind
We discuss budget and construction access alongside the design options, especially where the existing home remains occupied. Builder and specialist input can help test assumptions before the documentation is finalised. Rental returns and overall feasibility require project-specific advice.
