2106 Vermont Ave NW, Washington DC

The imperative for resilient housing concepts has never been greater. The three challenges of unprecedented urban population growth, drastically increasing climate change impacts and the disturbing sociocultural trends of divisiveness, tribalism and social isolation, are exposing the ineptitude of traditional housing solutions. Coliving, on the other hand, has the potential to make a difference with its inherent sustainability and its self-fulfilling reliance on community in the biggest sense. 2106 Vermont Ave NW is the creation of a design prototype for urban coliving providing 9 residential units, 51 bedrooms, unit and building congregation spaces, and a retail space to link it to the neighborhood.

The main facade engages Vermont Avenue with its massing as well as the implementation of brick detailing paired with wood paneling. The fenestration is strategically placed to optimize daylighting and minimize heat gain, contributing to the energy efficiency of the units.

The project provides opportunities for the blending of indoor and outdoor space both within and beyond the coliving units. The rooftop amenity space promotes and encourages community, while the private bedroom and shared unit balconies allow for a place of solace; each contributing to the mental wellness of the occupants.

The court in the center of the building allows for additional light and air to enter the units and carves out additional space for unit balconies, affording occupants with a more secluded experience removed from the street and alley.

Atlas District, Washington DC

OSLOatlas is the recipient of a 2017 Washingtonian Award in the multi-family category and a finalist for the Urban Land Institute (ULI) 2018 Real Estate Trends awards.

OSLOatlas is an urban infill project on Florida Ave NE in the growing Atlas district. The area has seen a rapid influx of young professionals in the last ten years. The development caters to this group with on-trend boutique group living. The building is an eight-unit multifamily project. Each of the eight units has five bedrooms, each with a private bath. This unique layout makes the units ideal for single professionals. The monolithic modern façade clad in manganese ironspot brick, is split down the center by a monumental entry court. The entry court design was partially driven by the need for an accessible ramp as well as the design team’s desire to provide a transition from busy Florida Avenue to the building entry. The ramp floats above a serene communal terrace located at the cellar level. The back of the structure brings vibrant color to an otherwise dull alley area. The rear façade contains a 40-foot-high, brightly colored mural by a local artist Lisa Marie Thalhammer. The building massing and stark materials create a striking and minimal design that elevates the structure from conventional new construction to a building with detailing and finishes typical of high design modernism.

Atlas District, Washington DC

In 2013, on the border between DC’s Trinidad neighborhood and the H Street NE Atlas District, the small strip of commercial space at the corner of Florida Ave NE and Orren St NE was abandoned and dilapidated. Today, the Corey brings new life to the corner and the neighborhood. The 40,000 SF, five-story mixed-use building contains 49 residential units and one retail space. Taking cues from the historic Atlas Performing Arts Center’s art deco design, the Corey combines historic art deco and modern design in its massing and material selection. The bold curved corner façade is clad with horizontal metal panel. The metal panels along with the sleek, steel canopy result in a streamlined modern finish. The building is divided into two masses which provide transition from the residential scale of the Trinidad neighborhood to the commercial scale of the vibrant and growing Atlas District. The two masses are differentiated by their use of material and separated by an entry court. A 30 foot tall sign further delineates the entry court that stitches together the two building masses and provides light to the building corridors and lobby. It is also the first project to be certified under the District of Columbia’s International Green Construction Code.

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.

Common Perry


1201 Perry St NE, Washington DC

This 8,700 SF, 7 unit, co-living apartment building is situated on the corner of Perry St. and 12th St. NE. The 3 story plus cellar and penthouse boasts a playful rhythm on both street-facing facades with the push and pull of the building. Light, horizontal fiber cement panels wrap around the darker, larger panel, resulting in a dynamic expression at corners and parapets. The horizontal paneling continues this wrapping/masking effect at the rear façade, extending over the walkways. The Rear façade also contains a highlight of the project: the metal-clad accent stair which boldly directs visitors inside.

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.

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.

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.

Atlas District, Washington DC

1115 H Street, NE is a 16 unit mixed-use condominium/retail project along the rapidly developing H Street, NE corridor. The design reinterprets the industrial typology of warehouse buildings once prevalent along the H Street corridor. H Street NE was one of the early business districts in the District of Columbia and home to the first Sears and Roebuck store in Washington. During the 1968 riots the neighborhood experienced severe damage and a period of decline. Construction was completed in 2016 and 1115 H Street NE was certified LEED Platinum in the District of Columbia.
