South Cathedral Mansions, Washington DC

South Cathedral Mansions is a historic landmark in the Woodley Park neighborhood of Northwest Washington, D.C. Prior to renovation the building contained 92 units. At project inception, the building had many large, dated and inefficient units.  The Square 134 renovation reconfigured units for improved layout efficiency and added 39 units for a new unit total 131 units.  The renovation brought all units to “Class A” standard of finish, added several amenities.  The design team worked closely with the owners to obtain both Commission of Fine Arts (CFA) and the Historic Preservation Review Board (HPRB) approvals for the project.

In 2017, the project received the Condominium Industry Award in Excellence for the Best Washington/Baltimore Apartment Community Renovation from Delta Associates. See all of the 2017 award winners here.

Atlas District, Washington DC

Linden Court is tucked behind the iconic Atlas Theater, a landmark and active performing arts center that was built in 1938 and served as inspiration for H Street’s moniker, the Atlas District. Linden Court was originally developed as ten rowhomes, six of which were combined and converted into a commercial property in the 1940s.

From the 1960s on, 1313-1323 Linden Ct NE was home to City Auto Repair, a locally-owned-and-operated body shop. In 2015, Monarch Urban acquired the property and began plans for its redevelopment into four luxury townhomes and a mixed-use commercial building. The 3BR/3BA townhomes feature private backyards, garage parking, and sweeping views of Capitol Hill from the private roof decks. The end unit is a commercial building with two units, one of which will have a dramatic 20-foot-high ceiling in the front of the space.

Mt. Vernon Square, Washington DC

This urban infill project is located in the Mount Vernon Square Historic District.  The once parking lot along M Street NW, fronts a block filled with an eclectic collection of architecturally diverse residences. Unlike other areas within the district, the rich architectural fabric along this street is comprised of individual unmatched houses that were built from the 1850s to the 1920s.  The pair of façades were designed to each have a separate aesthetic that also refers to the surrounding historic rowhouses.  The project’s masonry detailing successfully organized the front facades, emulating the consistent rhythm of unique façade patterns found along this block.

Designing the pair of façades to each have a separate aesthetic specifically references the surrounding historic character and allows both the history and architectural diversity of the block to be sustained for years to come.  The heights of the new houses comfortably fit with their neighbors by placing the mansard house against the short two-story flat and locating the taller three-story house to align with its adjacent three-story historic neighbor.  The facades are articulated by a variety of brick coursing patterns and string courses, including a band of header courses at the top of the second floors and a stacked bond pattern for the top floor of the three-story house.  The masonry detailing successfully organizes the front facades, emulating the consistent rhythm of the unique façade patterns found along this block.

The design also supports the well-being of its occupants.  The project scope focused on enhanced building performance by meeting today’s energy standards.  This included optimizing the HVAC systems, maximizing fresh air, both mechanically and through operable fenestration, and providing ample natural light.  Each unit also has access to private outdoor space.  The backyard provides an intimate patio space for the two lower-level units and the rooftop decks provide an expansive space with city views for the upper-level units.  The proximity to an active commercial corridor and neighborhood amenities also promotes walkability.

Mount Joy


Capitol Hill, Washington DC

The church and its adjacent row house were renovated simultaneously to become luxurious condos and a single-family home. Being a detached building from its adjacent neighbors, the church provided many opportunities to create well lit residential units and its height allowed us to create some unique 2-story spaces. The project consists of eleven units and four parking spaces and was completed in 2017.

Logan Circle, Washington DC

This boutique condominium project features nine multi-story units appointed with high-end finishes and first class views of the historic Logan Circle neighborhood of Washington, DC. Our design team worked closely with the Historic Preservation Office in Washington DC to ensure the conversion to condominiums respected the historic value of the original structure, built in 1892.  At project commencement, the original three-story brick home at the corner of Rhode Island Ave NW and 12th Street NW was occupied as a single residence. The renovation and conversion project undertaken by Square 134 worked to retain historically significant interior and exterior details.

Atlas District, Washington DC

Since construction, the original two-story storefront was home to various retailers, including a furniture store, a shoe repair shop, and a barber shop. The store storefront was vacant from 2012 – 2015. Our redevelopment of the historic building, following purchase by new ownership, included a two-story retail space with two residential units above. The residential space brings in a new material and is set back ten feet to respect the existing façade while still complementing it.

The residential portion includes a one-bedroom, one-bath unit with a rear balcony and large terrace and a two-bedroom, 2-bath unit with front and rear balconies, and a large private roof area with views of Union Station, the Washington Monument, and the US Capitol. The two-story retail space features a dramatic 20-foot-high ceiling, a loft area with private deck, and a full basement.
