Our Site sits on the edge of the historic Haymarket and the new Haymarket developments. This site is a literal crossroads with high pedestrian traffic traveling through our site from the parking garages to the west.

Our building design with an entire site spanning bridge maintains an urban streetfront presence across the entire canopy street side while allowing free-flowing access to the public square set back within the site’s footprint.

Our Form finding began with identifying major alignments between our site and the surrounding context. We identified the northern portion of the site as an ideal place for the market hall as it is the most heavily trafficked area while the services would back up to the O Street overpass.

This created distinct forms surrounding a public square in the middle. Maintaining an urban street front was another focus so the second floor became a site spanning bar that allowed the building to have a block spanning presence but also framed the public square. The final piece of the form is the tower. While the lower levels respond to the older Haymarket context, the tower responds to the new Haymarket. We also wanted to provide additional residential units that drove the tower upwards as we wanted to limit the residential footprint on the overall site.

The high traffic passageway to the north of the site directly connects to our market hall allowing people to easily access the space. The market hall’s form guides people from the old Haymarket into the public square where outdoor markets can be set up. The upper bar also extends beyond the site boundaries framing passageways on the north and south sides of the site.

The residential tower stands tall on the south side of the site sheltering the public square from the noise of the overpass. This also gives residents views into the Haymarket from their balconies.

The Nolli plan shows accessible space to the public within our building.

The public is able to freely flow through the market hall into the public square and then to the cafe on the south of the site. With our support spaces backing up to the overpass we maintain an entirely public presence along canopy street.

The ground floor of Market Station features the market hall to the north and the residential lobby and restaurant/cafe to the south.

The ground level makes use of lots of glass and brick to tie into the existing context of the Haymarket district.

The second-floor bar contains artist studio spaces as well as a gallery to house community art exhibitions.

The second floor makes use of a glass and metal panel system to distinguish itself from the ground floor. The residential tower is mostly glass with light-colored sandstone and metal panel accents.

The art studios span over our major entrance into the public square. This was meant to create an interaction between artists and the community as the artists will have views into the public square, and the public will have partial views into their studios with large picture windows that they can use to display their art to the public. The public square was designed with a large amount of open space so that the market hall can house more stalls outdoors during nice weather.

The first floor features our primary public spaces including the market hall, cafe, and the residential lobby. Also featured on the southeast section of the site are the support spaces including the kitchen, trash room, loading dock, and mailroom. The market Hall is positioned at the crossroads of the site to take advantage of the foot traffic between the old and new Haymarket. The cafe is removed from the street front and faces onto the public square providing a quiet atmosphere. The residential lobby is located directly off canopy street and serves as the main entrance for residents and the resident-only elevator.

The second floor contains slightly fewer public spaces including the studio spaces, gallery, and office space.

This level connects the two separate first floors and frames the public square.

The studio space is then able to overlook directly onto the public square. This allows a visual connection from the studio spaces to the public.

The private residences portion of this project stack vertically into an 8-story tower. This allowed us to greatly increase the volume of residential units providing 28. The residences are configured in a loft with the bedroom and bathroom being on the second floor. The residences sit on a single loaded corridor allowing each unit unobstructed views to the North and South with the loft. All units have a private north-facing balcony right off the living room. The eastern and western units also feature a second-level balcony off of the bedroom.

The Roof features our air intakes and other HVAC equipment as well as a roof deck for residents

The tower structure of Market Station utilizes two large concrete beams which are tied into the concrete cores. The rest of the structure above the concrete beams is a long-span CLT/Glulam system which is able to take advantage of the concrete beams below in order to prevent longterm sag and bending of the wooden structure. The entire structure is either tied into and supported by the two concrete beams or the concrete cores.

3D Structural Diagram

Market Station utilizes a central hydronic HVAC system to heat and cool the majority of the building. Apartment Units are provided air through the central heating and cooling system but feature individual VRF units to further heat and cool the space to their liking. A DOAS (Dedicated Outside Air System) is included on the roof of the residential tower to provide fresh air to occupants of the tower. Water retention systems collect rainwater from the roof surfaces and drain it into cisterns in the basement. Hot and cold systems throughout the building utilize the same ductwork. The central heating and cooling system are adjusted for different seasons to maintain a comfortable temperature, and apartments utilize VRF (Variable Refrigerant Flow) systems to individually heat and cool further to their liking.

Building Systems

21

The daylighting strategy for the building focused entirely on the western facade.

The Southern facade is shaded on the lower levels by the overpass.

We identified the market hall to be the only space in need of minimizing daylight exposure. To minimize sun exposure in the market hall during afternoon hours we exploited vertical shades that are placed at ten-foot intervals across the facade.

Daylighting

Our rainwater retention system is able to collect around 50,000 gallons of greywater for use throughout the building. It also makes use of a green roof which is able to retain water and slow its drainage into city stormwater systems.

Handrails stand 36 inches high and have 2-inch spacing from the wall. There is a 44inch egress path between railings and the minimum required door size of 36 inches. All Doors swing in the path of egress.
