A Boutique Building with Remarkable Design

Designed by the acclaimed architecture and design firm Hacin + Associates, Four51 Marlborough takes cues from the surrounding brownstones and reinterprets them with a clean, contemporary twist. Historic materials are used thoughtfully throughout the building, offering subtle nods to Boston's past while embracing forward-thinking design. The result is a structure that feels both timeless and ahead of its time.

Inside, each home features multiple exposures and thoughtfully designed layouts that maximize natural light and functionality. French balconies and private terraces add a European flair to the living experience, while wide plank flooring, high ceilings, and tailored architectural details create spaces that are elegant yet livable.

Residents are welcomed by a custom-designed lobby that feels more like a boutique hotel than a typical condo entrance. A concierge is on hand to assist with daily needs, adding an extra layer of convenience and service that complements the lifestyle at Four51.
