Property Type: Flood-Damaged Single-Family Home

Project Overview

After a major attic flood damaged the second floor and parts of the main level, the homeowners saw an opportunity to rebuild—not just restore. Rather than returning to a single-family layout, they brought us in to reimagine the property as a legal 3-unit dwelling, maximizing value and rental potential out of a challenging situation.

Scope & Strategy

The design reconfigured the property into two independent ground-floor units plus one full unit on the rebuilt second floor, while using the reconstruction to modernize systems and improve resilience.

  • Reconfigured the layout to accommodate two independent units on the ground floor plus one full unit on the rebuilt second floor
  • Integrated fire and sound separations, independent mechanical systems, and OBC-compliant egress for each dwelling unit
  • Leveraged the damage as an opportunity to modernize systems, upgrade insulation, and create long-term rental value

Challenges Solved

  • Converted a partially gutted structure into a triplex without exceeding the original building footprint
  • Navigated post-flood reconstruction requirements alongside zoning and permit approvals
  • Designed a fire-safe, energy-efficient, and code-compliant multi-unit setup within a formerly single-family layout

Investor Benefits

  • Transformed a distressed property into a fully legal triplex with three income streams
  • Increased long-term property value through smart layout, modern systems, and proper documentation
  • Reduced future risk by integrating fire-resilient design and updated materials throughout

Current Status

Triplex layout and permit approved. Construction nearly completed.
