The challenge
Mechanical systems for a ground-up 5-unit condo building on Portland's East End.
What Mash installed

A tight urban site with no laydown space and a compressed construction schedule.
The outcome
Each unit delivered with its own efficient, quiet system, turned over on schedule.
Project Overview
56 Cumberland Ave is a ground-up, five-unit condominium building on one of the last remaining buildable lots on Portland's East End. Built with M.W. Hoss Construction and designed by Delano Architects, the project called for a tight, well-coordinated mechanical package on a dense urban infill site with limited staging and access.
Mash Mechanical delivered the heating, cooling and ventilation for the building. Each condo is individually zoned so owners control their own comfort, with high-efficiency equipment, quiet distribution and code-compliant fresh air and exhaust throughout. Riser routing, unit layouts and finish details were coordinated closely with the general contractor and architect to keep mechanical fully concealed in the finished spaces.
Scope of Work
- • High-efficiency heating and cooling for all five condo units
- • Individual zoning and thermostat control per unit
- • Kitchen, bath and dryer exhaust with make-up air
- • Fresh air ventilation to meet code and comfort requirements
- • Riser and ductwork coordination with structure and finishes
- • Test-and-balance, startup and commissioning
