Bainbridge Play Cafe coffee bar — Harmony House hospitality design
Hospitality Design

Built for the
Public

Coffee shops, community spaces, and public-facing hospitality environments — designed for warmth, community, and commercial-grade performance.

A coffee shop is one of the most technically demanding builds in commercial design.

The warmth, the community, the quality of light at 7am — these are the things that make a coffee shop worth coming back to every day. They are also the last layer of a project that begins with grease interceptors, three-phase power, vent hood suppression systems, health department plan review, and fire marshal approval.

Harmony House has built the expertise to carry a hospitality project through every layer of its complexity. We coordinate the plumbing engineer, the mechanical engineer, the electrical engineer, the health department, and the fire marshal — while designing a space that feels like the infrastructure was never the point.

Seven Systems Every Hospitality Project Must Get Right

01
Permitting + Inspections
Building permits, health department plan review, fire marshal, and ADA compliance — all must be mapped before design begins. The permitting sequence is a design constraint, not an administrative afterthought.
02
Plumbing Infrastructure
Three-compartment sink, dedicated hand-wash sinks, floor drains, and a grease interceptor sized and located before the slab is poured. This is the most complex plumbing scope in commercial design.
03
Electrical + Power
Espresso machines require dedicated 240V circuits. Each piece of equipment has its own amperage requirement. Panel capacity and circuit layout are resolved in the design phase — not discovered during fit-out.
04
Ventilation + Vent Hoods
Type I hoods with integrated fire suppression, balanced make-up air, and an HVAC system sized for equipment heat load, steam, and high occupancy. The hood is only as good as the make-up air that balances it.
05
Equipment Specification
Every piece of equipment is scheduled at project outset — manufacturer, model, dimensions, power, plumbing, and ventilation requirements — and issued to the engineers before mechanical and electrical design begins.
06
Health Department Compliance
Sink counts, locations, floor materials, food-contact surfaces, refrigeration, and lighting levels are designed in from the start. Retrofitting health department compliance into a near-complete design is expensive and always a compromise.
07
Guest Experience
The seating mix, counter design, acoustic treatment, lighting layers, and material palette that turn a compliant commercial kitchen into a place people genuinely want to be — every morning, for years.
The infrastructure makes it functional. The design makes it worth coming back to. Both require the same level of intention — from the first permit application to the last coat of finish.
