01 · Site

Read the lot first.

Zoning, survey and feasibility before anyone commits—so the building fits the site and the block.

A vacant infill lot is where every one of our buildings begins.

Lay it out before we dig.

Drawings, budget and schedule with licensed design partners, and permits carried through the City of Philadelphia.

The building is laid out on the lot, so every trade follows the same plan.

What we do

Small buildings, built with the discipline of large ones.

We take a vacant lot from permit to certificate of occupancy. One builder accountable for budget, schedule and quality—start to finish.

How we work

Focus

Three commitments.

  1. 01

    Ground-up multifamily

    Three- and four-unit buildings on infill lots zoned for multifamily use, including RM-1. One building type, done well.

  2. 02

    Accountable delivery

    Pre-construction, permitting, trades and site supervision under one contract. Clear budgets. Honest schedules.

  3. 03

    Built to hold

    Specified for long-term ownership: durable envelopes, efficient systems and finishes that age well.
