INTRODUCTION NICOLE FICHERA Northeastern University School of Architecture housing studio focuses on a different type of housing every year, from courtyard housing to high-rise multi-family buildings. When our instructors told us that we’d be designing rowhouses, I was excited. As students in Boston, we know rowhouses: we have all lived in them, walked by them, partied in them, chatted on their stoops and relaxed on their rooftops. Architecture studios so often deal with big buildings and large-scale urban plans—this presented a chance to think on a smaller scale, something tangible and intimate. Design of housing focuses on something we all do every day: live. We all live, and we all want to live well. As students, this was our charge: to reinterpret the rowhouse for modern urban life.

At the onset of the semester, our instructors presented six basic diagrams for our rowhouse prototypes. Based on a parcel size of 20’ x 60’, the diagrams established a basic framework for interior spatial organization and the adjacent parcels in relation to one another. ‘Push/Pull’ required the deformation of the party wall between two parcels, allowing units to expand and contract laterally to create wider spaces. ‘Interlocking’ rowhouses broke down the

the ways in which cities struggle to move forward within the constraints of the past. In cities such as Boston, New York, Philadelphia, and Baltimore, rowhouses are commonplace. Multiple generations of people love them. They make neighborhoods feel unified and urban, create a comfortable sense of human scale, and express the individuality of a single home. Historically rowhouses signified progress and momentum forward. In Boston’s Back Bay and South End neighborhoods, rowhouse builders were pioneers on land filled sea. Now antique facades seem solid, placid, full of untold stories from a genteel past. Rowhouses have been so often subdivided and readapted to modern living that their rhythmic, uniform facades hardly reflect their diverse and heterogeneous innards. But these neighborhood relics are not always perfectly preserved and have adapted to accommodate change over time. It is essential to acknowledge that diversity exists within rowhouses. Recognizing the natural evolution of living spaces could—and should—have major implications in the creation of new housing today. As an individual expression in a cohesive urban framework, the rowhouse gives us both a sense of collective and a place to call our own. In a city such as Boston, the reinterpretation of this multi-generational precedent results in the creation of new housing types, ones that are undeniably modern, but also intrinsically rooted in Boston.

JULIEN JALBERT

Upon first designing a siteless rowhouse, this scheme placed

INSTRUCTOR

the public program towards the more active street, and the

ALYSON TANGUAY

private program towards the alley. An outdoor space was

ADAPTABLE LIVING SPLIT ROWHOUSE

ADAPTABLE LIVING placed in between the program, and the circulation was situated around the void created. Once a site was given, the overall parti of the design was modified to accommodate solar orientation, where north-facing units would reorient public program toward the rear. Public alley gardens were also placed adjacent to the north-facing units on the block, which also facilitated the reorientation of public vs. private program.

17

JULIEN JALBERT INSTRUCTOR TANGUAY

The design looks to create open (green) spaces at three different scales that work in unison in order to create an engaging urban residential site. First, at the small scale of the unit, courtyards are either shared between units or individualized for the row house, allowing for more privatized exterior space for inhabitants. Second, at the intermediate public scale, contained gardens for each individual block, allows for a sense of community within the block. Lastly the large scale open space for the general public create liveliness within a urban setting.

Only at two specific living spaces, does the house connect directly with the public: on the roof courtyard and in the main living room space. The organization of the unit around a central courtyard allows for flexibility of unit types, where two units can easily be paired to create a large center courtyard while still maintaining an identity for a single unit type.

DAN ADAMS

The inspiration for this design came from the phenomena of

the suburban lifestyle. Freedom of the outdoors and access

MICHAEL GROGAN

to exterior living space lead to the question of how to make

URBAN SUBURB SKINNY ROWHOUSE

URBAN SUBURB this possible in an urban setting. The most logical answer was to utilize space on the roof which typically goes unused. Combining the “Skinny Rowhouse” typology with a centralized stair core and access to the roof resulted in a balanced programmatic distribution of space. The stair simultaneously maintains privacy along the vertical axis for the bedrooms on either side and brings guests to the public space on the top floors.

39

The urban aggregation strategy is based upon two main goals—creating density and encouraging urban neighbors. By providing rooftop yards, residents will have the same opportunity to develop relationships DAN ADAMS INSTRUCTOR GORGAN

with neighbors just as residents do in a suburban context. This is made possible by providing a high level of dense aggregation.

The existing bike path remains to be used as a termination point for pedestrian walkways. Two formal green spaces were also added in order to balance density with open green spaces. Site Diagram - Major/Minor Axis

BLURRING BOUNDARIES SKINNY ROWHOUSE

BLURRING BOUNDARIES private bedrooms were placed into two boxes, both opening outward to enjoy light and views from either end of the unit. The negative space between the two boxes became the public space. Two unit variations resulted from flipping the orientation of the unit from back to front. One unit type had a 2 story street front while the other had a 3 story street front allowing for a distinction in composition between major and minor streets and streets bordering green spaces. The major streets were composed of the taller units repeated rhythmically with the facade designed in a way to excentuate the skinny quality and height of the unit. Minor streets and those bordering southern green spaces were arranged with an AB pattern that allows light to penetrate deeper into the site.

The interlocking rowhouse strategy provided me with an

opportunity to explore a different type of living experience.

DAVID HACIN

The nature of the interlocking typology allows units distinct advantages over the typical rowhouse typology. First, rowhouses are not bound to the typical front-to-back layout which minimizes facade exposure and limits floor plan layout. Interlocking units can push and pull in various ways to allow for

MAXIMUM EXPOSURE PUSH-PULL ROWHOUSE

a more comfortable living arrangment while maximizing facade exposure. Second, the interlocking strategy allows for units and their occupants to interact in ways otherwise not possible. The interlocking of units creates overlapping of volumes and opportunity for visual and physical access to shared spaces.

WHITNEY CHICOINE

The nature of the push-pull rowhouse type allows for the

INSTRUCTOR

designer to take advantage of a flexible party wall. In my

ALYSON TANGUAY

design, there is a shared zone between two row houses where the party wall undulates back and forth. This provides the opportunity for certain rooms to get larger where they need to, and for the circulation space to take up less space in the individual units, by sharing one zone. It also provides an

FLEXIBLE PARTI-WALL PUSH-PULL ROWHOUSE

opportunity for a shared light well to bring natural daylight into the center of the units. The party wall is thus semi-transparent at points to allow for natural light to penetrate into both units, from above and from the front and rear facades, while maintaining proper privacy between the units.

DEVIANT ROWHOUSE ALEXANDER DAVIS

What is a Rowhouse?

INSTRUCTOR Does it repeat over and over again? Does it share a constant parti wall? Does it keep a constant street edge? Throughout the development of this project, at both unit and site scales, there was a constant idea to test the boundaries of what a neighborhood of rowhouses should and can be. Although the design scale varies throughout, the concept remains the same. At both unit and site scales, the pedestrian

travels along a threading circulation path that stitches spaces together (apartments or blocks). This resulting corridor ends in either an exterior terrace or large recreational area. The resulting design, although deviant from normal Rowhouse design, explores the possibilities of the rowhouse archetype.

107

At the site scale, the varying blocks are treated very similar to the various apartment units at the unit scale. A pedestrian corridor threads its way through the site much like the main staircase threads through each rowhouse. This pedestrian corridor meanders through the site connecting each block with important existing buildings, proposed commercial space and large recreational areas. As this corridor passes through blocks, open spaces are created that allow for various social and recreational activities to take place.

The idea for my unit and master plan is to blend families

INSTRUCTOR

and working singles. The unit plan, while balanced in square

footage, has more bedrooms with less living space for the working singles, and fewer bedrooms and more living space for the families. The blocks on the North edge of the site feature the family units, blocks on the South edge of the site feature multi-tenant Live work units line the blocks along Melnea Cass. The green space on the site is a combination of two large parks, one for families and one for working singles, and a buffer zone between housing and the busy Melnea Cass Boulevard.

The master plan is arranged according to major thoroughfares and existing neighborhoods. Family housing is close to the housing developments in the Northwest edge of the site while multi-tenant housing is close to the major businesses and commercial areas lining the site. Major pedestrian roads respond to the parks and retail areas of the site.

VOID + WEDGE DENNIS GREENWOOD

The project explores the typology of the rowhouse (specifically

INSTRUCTOR

duplexes over a flat) by removing party walls, a typically

ALLYSON TANGUAY

defining characteristic. A void replaces the party wall and becomes an exterior zone of pushing and pulling private spaces. This creates a reciprocal relationship between the units while allowing light and ventilation to reach the flat below. This “void” space then becomes a flexible zone in the geometries. A wedge shaped variation of the design allows a strip of rowhouses to curve along the block. In a similar approach, wedge shaped greenspaces are used on the larger urban scale to regulate city block geometries.

The site seeks to bridge the divide created by Washington Street while providing a buffer from the Melnea Cass thoroughfare. First floor retail units line pedestrian friendly Washington Street and a bike path and row of streetside trees skirt Melnea Cass. Rowhouse variations were created to satisfy the needs of the site and the principles of the design. The greenspaces are designed to regulate the city blocks, while creating a focal point within the site.

The site is split into three different zones, each of which has its own interior community open space.

Retail space is spread throughout the site in two different ways. The first, which can be seen along Washington street, is the “exterior facing” retail meant for the general public. Here the retail would be located on the first floor with duplexes above. The second type of retail is the “interior facing” retail which is located inside each of the zones. This would be community space for the people who live in the area. This interior facing retail has two different unit types. In the first type the retail is on the ground floor with the duplex units above. In the second type, seen on the corners, community space happens on all three floors.

The interior-facing retail space has a large buffer zone between the street and the open space that becomes a walking arcade. This connects all of the retail space and also becomes a part of the pathways that connect the corner community spaces.

THICK ZONE CORE NICOLE FICHERA

This project is based on a basic unit type of two duplexes

INSTRUCTOR

over a flat. The main concept is the expansion of the party

SAM CHOI

wall between the two vertical duplex units into a thick zone, which contains all of the closed poche functions for the entire building: primarily circulation, bathrooms, kitchens, closets, laundry, et cetera. Attached to the thick zone on each side are closed bedroom the units (service and sleeping) occur in the closed volumes of the bedrooms and the thick central core. The public living spaces (kitchens, dining rooms and living rooms) are then formed by the open interstitial spaces between these closed elements.

The diagram at right depicts the unit concept as applied to the block. The central thick zone within the unit is conceived as something which is experiential—you are required at all times to interact with it and pass through it to get from space to space. By applying that concept to the front of the aggregated block, a thick facade zone is formed which mediates between the private world of the unit interior and the public life of the street.

The elevation is conceived in terms of the block as a Edge Block Elevation Axonometric

series of carved layers and frames with a projecting living room volume. The layers make the thick zone inhabitable in the same way as the core. On a larger scale, the concept of a thick zone is used to form a plan based on superblocks. The size of the blocks responds to the character of the site. It

is a part of the South End, which has a fine-grained rowhouse texture, but it is additionaly a fringe condition, surrounded by strips of industrial and medical buildings. Thus, a modified version of the block elevation incorporates a block-size unifying frame element, and has less projections (which serve to break down scale). Thus, the edge walls of the super-block are unified and read as larger scale, and Thick Zone Applied to Block Facade

The inhabitable core is modified by a series of additive and subtractive operations. Spaces are carved out of the thick zone for spaces such as bathrooms, kitchens, and circulation. In other cases, the core expands, sticking out into the room with balconies and fireplaces. The nature of a rowhouse is to have long, narrow spaces; by making the core inhabitable and letting it divide spaces by pushing out, the rooms can be divided into more appropriate proportional dimensions. In the flat unit, the core breaks off into smaller pieces, allowing a kitchen space in the center. In all three units, the user constantly moves in and out of the core, using it as circulation and inhabitable space. Gaps in the third floor allow the core to read as an uninterrupted wall rising through the space. The separation of the bedroom volumes on each end creates a dramatic open vertical space above the dining room, Unit Section

The goal of the housing project was to create an ultra

pedestrian friendly master plan that would draw pedestrians

from the Boston Medical Center west of the site as well as pedestrians from the apartment complexes to the north. In order to do this a hierarchy of open spaces is arranged to tempt public use. To draw users from the apartments a baseball/recreational field was placed at the Northern most edge of the site. Likewise a vast stretch of landscape tempts the site. These open spaces are attached to a single road going through the site about which smaller open spaces are arranged to encourage travel to the commercial center along Harrison Ave.

units that share one parcel. The units interlock volumetrically,

wrapping around each other across the parcel and each consisting of three volumes. The dynamic shift in shape and size of the volumes changes in response to the parcel dimensions. The top volume holds private program, the middle public, and the ground a mix of both. All circulation through the units is located in the center of the parcel along the party wall that separates the two units. Additionally, each unit has an entrance from the street as well as access to a back alley,

The site is bound by prominent existing roads. By extending these roads through the site, I was able to create a grid, broken into three zones, within which I placed the city blocks. The size and shape of these blocks picks up on nearby existing urban fabric patterning. A belt of greenspace acts as a buffer along Melnea Cass Boulevard in each of the zones.

There are two different unit types included in my aggregation: the interlocking unit type (below) and the stacked duplex unit type (right). These types yielded multiple unit variations, some accomodating retail space on the ground floor or adjusting to meet a block corner condition. The varying unit types were then used to create patterning in the block schemes as well as the overall site aggregation.
