What Stack + Co. does
Stack + Co. is a Boston-based construction management and design-build firm operating since 2008, focused on multi-family residential developments and commercial buildouts in the greater Boston/New England market. The company delivers projects ranging from approximately 12,000 gsf residential additions to 40,000 sf commercial facilities, with notable expertise in adaptive reuse, vertical additions, and complex urban infill construction. Its portfolio includes the ICA Watershed (a 15,000 SF adaptive reuse of a WW2-era copper pipe factory completed in 28 weeks), the Box Office project (the first permanent multi-story commercial shipping container structure in the US), and the 52 Plympton CLT residential development built to Passive House Standards.
The company operates an integrated design-build model in which it sometimes serves as both Design Architect and Construction Manager on select projects (e.g., Parmelee Street Apartments), capturing value across the project lifecycle. Revenue is earned through project-based construction management fees on fixed-price or fee-based contracts with direct client engagements, sourced primarily through reputation, portfolio quality, and developer/architect referrals rather than formal sales channels. Its customer base spans multi-family developers, hospitality operators (Blue Bottle Coffee, SPiN, Pammy's, Orfano, Dorchester Brewing), retail tenants (Blu Dot, Buck Mason), fitness operators (BKBX, BKB Lincoln Park), cultural institutions (ICA), and technology/research organizations (Robotics and AI Institute).
The firm is founder-owned by Joshua M. Brandt, with a leadership team of 11-50 employees including a Director of Estimating with 20+ years of New England market experience, project executives, project managers, superintendents, and a controller. Stack + Co. has begun selective geographic expansion into Providence (The Green Link partnership with Brass Rat Inc.) and Chicago (BKB Lincoln Park), and vertically integrates into real estate ownership by self-developing select projects such as 52 Plympton. The legacy architecture studio was spun off as a separate MBE firm, Stack Architecture, allowing the parent entity to concentrate on construction management.
