I have elected to consider the problem of urban medium density dwelling and will focus on fostering a superior relationship between the medium density dwelling and the city. This exercise will be directed towards understanding the issues and problems of the three to four storey main street mixed use residential /commercial building. In my project, I will focus on first, reinterpreting the boundary between the private spaces of the apartment and the public space of city, second, on improving the transition from the public to the private and third, providing a livable environment within the high density of the city. I will dissect the city/dwelling relationship into three constituent parts Urban networks within the fabric of the building, Interstitial (or transitional space) and the dwelling. These conditions, which will be outlined in detail, serve as a frame in the discussion of how to create a meaningful connection between the city and the urban dwelling. Urban networks within the fabric of the building: An internal street and exterior entry and circulation for all units has been introduce to enhance the ideas from the previous paragraph and allow a piece of the Urban realm to become part of the dwelling. Further, urban program such as office and commercial units and parking are invited into the envelope of individual dwelling units Interstitial Space: By focusing on the concept of interstitial spaces ( or zones in the project which contact the public urban realm) I intend to respond to the changing conditions of the city traffic flows, noise, sinage, and qualities of light from front to back. The concentration on the design these in between spaces will allow the inhabitant to maintain a connection or view to the public nature of the city yet at the same time allowing the inhabitant to mediate this connection through controlling the degree of exposure to the city. As a result, the dweller has the option of experiencing the public nature of the city while enjoying the privacy which dwelling traditionally provides. The Dwelling: It is my intention to prevent the isolation of the apartment from the city in part by carefully considering the transition from the city to the apartment and the apartment to the city. Therefore, the issue of the threshold or the space between the city and the apartment is central to this argument. All apartments have at least two ends open. The units are long and narrow increasing density while still allowing two ends open. A concrete party wall separates each apartment reducing the need for structure at the front and back to allow light and maximum opportunity for transitional zone between the dwelling and the city. 3 High Density Dwelling Space in the Urban Center David Kay The Project: Although I have chosen a specific site I intend to respond to the generic issues and problems of the mixed use infill urban dwelling. The site is located on fifteenth Kingsway in Vancouver. The proposal is an infill building in an existing neighborhood. I have chosen three thirty three foot by one hundred foot lots mid block. The proposed building has an FSR of 2.6 and is mixed use with dwelling office and commercial space. Unit A: six units each with a parking stall and storage at the commercial space at the street front and living space above commercial. Unit B: Consists of six two bedroom units at the ground plane, private outdoor space, direct access to the alley and an option of personal parking and storage bellow the unit. Unit C: consists of six bachelor apartments which are fully open at two ends. Unit D: six single bedroom units with living on the ground floor, bedrooms on the fifth floor and a outdoor space provided at the center of the living space. 4 High Density Dwelling Space in the Urban Center Urban Networks Within the Fabric of the Building: The city and the mixed use dwelling unit (traditional single or double loaded units). the project is an alternate to dwellings which are disconnected from the city with internally articulated circulation and no transition between the edge of the unit and the city. I will now describe (traditional single or double loaded units) in order analyize the problems of the disconnection from the city within this type. Plate One: The City: Urban Networks.

For the most part in traditional dwellings on these streets there is little or no transition between the dwellings and the city at the front or the back beyond window wall or small deck space. This parti describes the position of the apartment in relation to the city. In the Parti the threshold represents the contiguous unbroken line which commonly exists between the city and these apartment blocks. This displays an order which will be disassembled in the following plates. i High Density Dwelling Space in the Urban Center ; David Kay_ Plate three: lists conditions encountered in traditional medium density mixed used dwellings: • Edges in cross section : There is little difference in the response to the changing conditions of the city or qualities of light from front to back • One end open: Generally one end open reducing the possibilities of natural light for dwelling or passage. • Open space Public/Private Few meaningful well defined open spaces. • The street edge its connection or disconnection between neighboring buildings one flat plane. Little attempt to respect the height of neighboring buildings in the two to three lot category • Response to Urban networks such as noise pollution sinage and light. Possibility of Dwelling and amenity space at the back ground plane • FSR is generally too low between 1.8 and 2.3 • Circulation internal m in u> m c o ._ c — o «,, N S O c — o (0 N c O z o n e l F r o n t a n d E n t r y In this typology, suites located in the back offer limited light and view. However, in some cases, terraces, fire escapes and external circulation provide a more complex transition from the dwelling to the alley. Units in the double loaded typology are typically small. In this example there are one bedroom and bachelor suites with a small kitchen and bathroom. Entry from the ground plane to the housing above is either from the street or the alley in some cases both situations occur. In this building access is from the street level with no access to the alley.

Generally, housing blocks in this category are two to three storeys high and open at one end only. Often, several older, single lot buildings will be joined at the front elevation while a common passage will be created to bisect party walls. ** The building on this plate located on the site at Kingsway and Fraser, represents a typical example of this category: - FSR 2.3 (including Commercial) -18 suites (double loaded) 7 High Density Dwelling Space in the Urban Center David Kay Response to the problems from existing types: Edges in cross section: Problem: response to the changing conditions of the city or qualities of light from front to back: • Focus on interstitial space. • A rich transformation in the characteristics of the apartment from front middle back and sky depending on the position in the site • Two ends open: This move begins to solve problems of light for passage and allows for selected apartments to have two ends open on one floor while all other apartments will have ends open at the front and the back Urban networks within the fabric of the building Problem: Disconnection to the city and lack of meaningful well defined open spaces. • Circulation/entry: Introducing an internal street into the plan of the building will allow for a penetration into the building of 'city like' outside circulation. Further, the impenetrable threshold begins to acquire a more complex relationship with the street and the city. One to three storey clusters of apartments above commercial are bisected by these internal streets allowing for semi-public communal space and outside circulation throughout the project. • Commercial and parking attached to unit • Private open spaces within the units. • Exterior circulation avoiding single loaded corridor FSR • FSR is generally too low between 1.8 and 2.3 I have increased the FSR to 2.6 by adding a fifth floor at the back and a forth floor at the front Overall, each space in the building to have some kind of quality connection to the ground plane and the city. The dwelling is provided clear view of urban networks and may have a direct connection to the ground plane and the city. 8 High Density Dwelling Space in the Urban Center David Kay Interstitial Space: An Exploration of the Boundary Between the City and Living Space. The crossection on the next page describes the order which exists at the threshold or, the boundary between the city and the building. Instead of direct passage through the knife edge between the building and the city, I propose to introduce depth to the threshold by providing passage through a semi permeable edge then into an interstitial space which exists between the dwelling/commercial space and the city. These space exists at points 1. The city to the commercial street screen for sinage, open to bellow display case over that bridge then window door then commercial space the bridge. The transition to the front dwellings screen void to bellow, bridge window and storage entry 2. Circulation intersections as with the study drawings the main entry to the dwellings, should not take up to much space away from the commercial. This move also provided a richer transformation between the edge of the building and the neighboring building. 3. Internal street landing and skylights 4. The backs of the front apartment this is the formal entry to the front units 5. Entry from the middle street to the back apartments is considered transitional and is a reaction against the closed passages of the type 1-3 dwellings. 6. The sky court for the uppermost unit serves as an internal interstitial space for that apartment. 7. The space between the house and the building screens for double loaded corridor at the back offer a visual block for house behind, there is an extra 1.5 meter setback to the alley and is an overall approach of quitter not heavy program at the back above the ground plane 9 High Density Dwelling Space tn the Urban Center David Kay Interstitial Space 10 High Density Dwelling Space in the Urban Center David Kay Dwelling: Responding to the city (see next page) Unit A. The front apartment: this apartment is a narrow tower entered directly from the internal street with parking and storage at the bellow grade level a commercial unit at the ground level and three floors of living space (Walk through from internal street) Unit B. The ground plane apartment is entered directly from the internal street has two bedrooms on the second floor and living space on the first floor, a connection to the alley. (Walk through from internal street) Unit C. This apartment straddles the internal street and the back and is entered of the internal street via a landing. The unit is two ends open, one bedroom and living space. Unit D. The sky apartment is more introverted, its internal court provides the dweller with a private space it is disconnected from the ground plane but shares a connection at the edges. It is entered from a single loaded corridor from a stair tower on the internal street or parking. It has living on the fourth floor and bedroom on the fifth floor. 11 High Density Dwelling Space in the Urban Center • David Kay A Parking Parking Apartment Key scale 1: 100 12 An Infill Housing Project in an Existing Urban Neighborhood David Kay The Site 13 • • 5 • • 0 DnorjODoO •DDDD a a • • n a • • • a • a • • a • • •• D • • i—J • • • • • • • • a n • • a • • • a a a a • a a a a • • B DDDO c a C/5 in i • •QOLXID o gaDOQDDDo^ nnnnnnnn nnnnnnnnn 16 An Infill Housing Project in an Existing Urban Neighborhood David Kay Plans, Sections and Elevations 17 18 UriitB: First Floor Unite I i i 19 id Fifth Floor Sea*':so'' • Unft 0 : Second Floor} 20 Front Etavation: scale T. 75 21 Front Elevation I — i i | j i ! i i 1 i | i 1 zzz;z r~ j rzzzz || i — 1 1 zzzz.i 1 J r_ zz I i 1 "1 ' — z ~~-^=7Z--sz '~-'jrrrz;:-'.rz;~ r 1—" t ^ Z Z u. _ J [ "i C Z Z _ J r " " ""] z^zz 1 I 1 ~] 1 J i._ _ J — .LZ_ Z J ! j ._. . i : J r I ! :_J E Z Z . i i i r ••• i ! 1 1 " "1 Z Z Z Z ] i— ~ 1 r zij. — L _ Z _ J • i • -.1 i i !'""'"' i j !
