01
ADU
Additional housing integrated thoughtfully within existing residential parcels.
Markets / United States
California development
& acquisition advisory.
Specialist support for developers and investors evaluating housing and infill opportunities.
01A Specialist Practice
Land, policy and project economics.
Our United States practice focuses on the intersection of land, housing policy and project economics. We support developers and investors in evaluating what a site may support, how evolving planning and housing policy may shape its potential, and whether the numbers hold.
With an initial focus on California, our work is designed for small and mid-sized developers, housing developers, land and real-estate investors, development firms and family offices evaluating infill and housing opportunities.
02Site + Policy + Analysis
From policy to development potential.
California’s evolving housing framework can create new possibilities for existing parcels and development sites. Infill evaluates how applicable policy, planning context, site conditions and project economics interact.
Applicability depends on current law, local implementation, site conditions and professional review. Our work is research and analysis, not legal advice, and does not guarantee entitlement outcomes.
Land
Parcel configuration, access, existing improvements and physical constraints.
Policy
Where applicable: SB 9, SB 684, SB 1123, ADU legislation and other relevant housing laws.
Planning
Local zoning, implementation, development standards and planning requirements.
Potential
Housing scenarios tested against market conditions, timing and project economics.
03Infill Housing Typologies
More housing.
More choice.
California’s housing opportunity spans a spectrum between detached homes and large apartment buildings — infill housing and missing-middle housing. We study how each form can respond to land, context, housing supply, development feasibility and project economics. Missing-middle and attainable housing describe scale and price accessibility; affordable and mixed-income housing refers to income-restricted programmes, and we treat them as distinct.
02
Duplex / Small Multiplex
Appropriately scaled housing that expands choice within established neighborhoods.
03
Townhomes
Compact family-oriented homes shaped around streets, paths and shared landscape.
04
Courtyard Housing
Homes organized around shared outdoor space at a human neighborhood scale.
05
Small Multifamily
Contextual housing between detached homes and large apartment buildings.
06
Attainable Housing
Development strategies that broaden housing choice, improve land utilization and support supply.
07
Affordable & Mixed-Income Housing
Site, policy, market and feasibility analysis for a wider range of housing outcomes.
Photography is illustrative of housing typologies and community outcomes studied by the practice. It does not depict projects undertaken, owned or developed by Infill.
04Community
Housing at the human scale.
Thoughtful infill can create more housing while preserving the qualities that make neighborhoods desirable — human scale, walkability, access, landscape and a sense of community.
