Mission Hill Triangle Architectural Conservation District

The Mission Hill Triangle Architectural Conservation District was designated in 1985.

The Mission Hill Triangle Architectural Conservation District Commission (MHTACDC) meets on the third Tuesday of each month to review proposed exterior design changes and alterations.

Design Review Process

All exterior work at front elevations, side elevations, or at rooftops that is, or will be, visible from any public way requires the review of the MHTACDC, with the exception of work occurring at rear elevations.  You must submit a Design Approval Application to the Commission and it must be approved by the Commission before beginning any exterior work that is subject to Commission review.

  • To save time and costs, please contact staff early in the planning process to determine project compliance with the standards and criteria.
  • Review all instructions and documentation requirements before submitting your application to ensure it is complete. Only complete applications will be added to a public hearing agenda.
  • Please review all instructions and documentation requirements before submitting your application.
  • Submit your application well in advance of a filing deadline in case it is marked incomplete and additional or revised information needs to be submitted.
  • Staff is not available to review applications for completeness immediately upon submittal.
  • Do not begin any work, or buy materials, until after you have received confirmation you project has been approved.

The Mission Hill Triangle area is in the original town of Roxbury, which occupied a prime location as the last town on the mainland before crossing the neck to Boston on the Shawmut Peninsula.  As the advent of turnpike routes, omnibus service, and rail lines improved access from Roxbury to Boston, construction of residential structures to accommodate the area’s growing middle-class population also increased.  Roxbury was annexed to Boston in 1868, leading to further expansion of urban transit systems and additional residential development.

The development of Mission Hill Triangle began in 1872.  The area was subdivided into 190 house lots ranging in size from approximately 1330 to 3000 square feet which were soon developed, primarily with single-family, two-story brick rowhouses, some with brownstone, sandstone, or marble facing.  These rowhouses are typically set back from the sidewalk, allowing for small, landscaped front yards.

Huntington Avenue was cut through the area in 1882, spurring the construction of three-story, multi-family residences at the ends of Worthington and Wigglesworth Streets, and of four-story single family houses on Huntington Avenue.  In 1884 and 1912, Mission Hill Triangle also saw the construction of a four-story hotel and apartment buildings.

The area is remarkably well preserved; nearly all of the structures built after 1872 are still extant.  These houses are visually similar, with most featuring a flat entry bay next to a projecting semi-hexagonal bay, and a flat or mansard roof.  Decorative details between groups of rowhouses vary, with elements of the Queen Anne, Romanesque Revival, Georgian Revival, and Second Empire styles all present in the district.

Mission Hill Triangle remains substantially intact, retaining much its original character and intimacy.  The district serves as both an example of a late-19th century rowhouse neighborhood and of the “streetcar suburbs” that sprang up in and around Boston during that time period.
