The developer of the Onyx Hotel in the Boston’s Bulfinch Triangle has plans to build a boutique hotel on a tiny parking lot in the neighborhood.

Wilmington-based LIMAC LLC wants to build a 15-story, 74-room hotel on a 2,159-square-foot parcel at Valenti Way and North Washington St. The site is currently occupied by a small former gas station structure and seven parking spaces.

The project designed by Boston-based CBT Architects would include a lobby, mezzanine and 13 floors of guest rooms, according to an application submitted this week to the Boston Redevelopment Authority. It would contain a lobby storefront and second-level lobby and cafe.

LIMAC LLC founder Tom MacKay acquired the property at 88 North Washington St. from longtime owners Peter and Olympia Limone on March 16 for $1, according to Suffolk County Registry of Deeds records. His Wilmington construction company, MacKay Cos., would be the construction manager. He is being advised by development consultant Fred Mannix of Boston, who was involved with the Onyx Hotel project.

The new hotel will fill in a “missing tooth” in the Bulfinch Triangle and mesh well with neighboring properties, Mannix said. The limited-service hotel will provide affordable hotel rooms in a city that sorely needs them, he said.

Aging commercial buildings in the Bulfinch Triangle are in demand as the neighborhood begins to be transformed with Boston Properties’ and Delaware North Cos.’ nearby $1 billion North Station redevelopment and HYM Investments’ $1.5 billion Government Center garage redevelopment both ramping up this year.

Woburn-based Somnath Hospitality received BRA approval in 2014 to build a 90-room hotel at the site of a vacant bank branch at 104 Canal St. That project has yet to break ground.
