Garage B at Charles River Speedway

Garage B is a flexible, industrial-cool event venue inside the Charles River Speedway in Brighton, MA, a restored complex of 1899-to-1940s buildings along the Charles River that now runs as a community marketplace of bars, micro-restaurants, and a Notch Brewing biergarten. Set in a revitalized 1940s garage, the 3,300 square foot space pairs original stone walls, steel beams, and polished concrete with floor-to-ceiling glass overhead doors that roll up onto a landscaped courtyard. It holds 160 seated or 240 standing, and suits couples and companies who want a blank-canvas, indoor-outdoor space with real character, minutes from downtown Boston.

What makes Garage B a standout Boston event venue?

It is a blank canvas that already has a point of view. The 3,300 square foot open floor plan keeps the original stone walls, exposed steel beams, and polished concrete, softened by large pendant lights and plenty of natural light, so the room reads industrial but finished. A bank of glass overhead garage doors opens onto roughly 1,700 square feet of landscaped courtyard that can be tented and folded right into the event, and year-round heating and air conditioning keep it comfortable in any season. The setting carries real history: the Speedway’s courtyard buildings once served as police headquarters, stables, and maintenance garages for the Charles River Reservation, a companion to the one-mile horse-and-bicycle racecourse that ran along present-day Soldiers Field Road. Today that courtyard is alive with Notch’s taproom, a sake bar, and a handful of micro-restaurants, so cocktail hour or an after-party can spill right outside the doors. At 160 seated or 240 standing, it is sized for intimate-to-mid-size celebrations in one flexible room, and a space like this rewards production that ties the indoors and the courtyard together.

How does Black Diamond produce events at Garage B?

This is our kind of room. We wash the stone and steel with custom uplighting, and we run sound that carries from the garage out to the courtyard, scaled well beyond the house system for a full reception. Our DJ and MC talent keeps the floor moving, photo booths and live musicians fill cocktail hour, and our photography and videography team makes the most of the industrial textures and the courtyard glow. For corporate programs, presentations, and wedding photo montages, we bring video screens sized to the room.

Common questions about events at Garage B

How many guests can it hold? The garage holds 160 seated or 240 standing across its 3,300 square feet, with about 1,700 square feet of courtyard that can be tented and added to the event.

Is it indoor or outdoor? Both. The glass garage doors roll up to connect the interior with the landscaped courtyard, and year-round heating and air conditioning keep it comfortable in any season.

Can Black Diamond transform a raw industrial space? Yes. We layer uplighting on the stone and steel, run sound that bridges the garage and the courtyard, and add screens for presentations or montages, so a blank canvas ends up feeling fully designed.
