1 | PROJECT BRIEF

(Urban)

Oasis:

/əʊˈeɪsɪs/ noun A fertile spot in a desert, where water is found.

The brief for this project is to create an escape from the urban world in the form of water - an aquatic centre, or swimming centre.

The project is to incoporate a main pool, and two leisure pools, and the space is to serve also as a centre of communal connections and relaxation.

PYRMONT

GLEBE

Project brief | 4 north sydney

The site chosen was within the Harbour side park - Pirrama Park, in Pyrmont, west of Central Sydney.

The site has direct view to both the Harbour Bridge, and the Anzac Bridge, and is situated across from a current industrailised/ construction site in Balmain, and also the White Bay Cruise Terminal. The pre-existing site is rich with local activities due to its waterfront feature. As such, the proposed Swimming centre must NOT cut off the connection which exists between the site, and the water.

5 | Site history

Named "pirrama" by the gadigal people of the eora nation.

pyrmont became one of the main sandstone quarrie responsible for numerous historical sydney buildings due to its reputable quality.

pyrmont was named after a spa town of germany for its natural springs.

1795, LAND WAS GRANTED TO THOMAS JONES, whom sold to Sergeant Ikin, then john macathur

with the "better cities program", pyrmont was REdevelopped in 1992, from its previously heavily

1877, pyrmont bath house opens to public, allowing local community to relax, bonding connections, and allowing local schools to teach swimming.

In 1870s, colonial sugar refinery company situates itself in pyrmont, morphing local community.

design development | 16

The preliminary design was rather plain with no real play of lighting and shadows, it was basically a glass box with timber columns. I decided to introduce specific lighting directions intergrated architecturally - mainly to light the pool from above, but not around. The layout was also slighting modified - the Plant room was changed to underground, the changerooms were more sophistically thoughtout, and the cafe slightly adjusted.

PRECEDANT STUDIES: tHERE ARE MANY PRECEDANTS WHICH HAVE INFLUENCED THE PROJECT, NOT ALL ARE LISTED BELOW.

21 | Precedant studies

PETER HALL PERFORMING ARTS CENTRE Architects: Haworth Tompkins Year: 2018 Location: Cambridge, United Kingdom Peter Hall Performing Arts Centre was the structural precedant for the project. The Grid Roof structure was chosen as the site was both long and wide, as such, a two way spanning system was optimal. The centre offsets the grid by rotating its axis by 45° from its vertical columns, by doing so, the roof beams diverts the visitors eyes outwards, providing a larger sense of space. A simillar concept is used, where the roof beams are incorporated in a way to guide the visitors vision. The roof beams are seperated by 5 meters, as such, perfectly lines up with the lanes of the swimming pool. The vertical beams leads the visitors attention towards the exterior view upon entry, highlighting the harbour bridge, whilst the horizontal beams provide a sense of space and speed when in water.

FREEMEN’S SCHOOL SWIMMING POOL Architects: Hawkins\Brown Year: 2017 Location: Surrey, United Kingdom Freemen’s School Swimming Pool succesfully provides the atmosphere of being surrounded by forest by only making the bottom half of the walls glass. The architecture is made to the human scale, and is one lesson which I took and applied within my design. To allow the visitors to experience the harbour side, not all walls need to be glass. As such, I changed the top halves of the original glass walls to solid walls, which convey a better delivery of light and shadow.

THE HUMAN SCALE.

25 | PRECEDANT STUDIES

JING’AN COMMUNITY POOL HOUSE Architects: PRA Year: 2020 Location: Shanghai, China Jing-an Community Pool house was the materiality precedant for the project. Shou sugi-Ban was the optimal material for the project as on the exterior, it provides weatherproofing, and a sense of industrialisation, tying back to the history of the site; and within the interior, its naturally dark tone provides an increasing contrast between the light, and the shadow.

MATERIALITY.

27 | PRECEDANT STUDIES

daylight house Architects: Takeshi Hosaka Architects Year: 2017 Location: Hiroshima, Japan The Daylight House influenced the design decisions made for the roof. Within the project, Takeshi Hosaka Architects incoporated a skylight within the center of each roof grid, and installed a dome of light diffuser underneath. In combination with the traditional pergola designs, by letting the fabric fall natrually, the curvature created serves as a natural light diffuser, blocking direct sunlight within the swimming centre.

29 | PRECEDANT STUDIES

LECA SWIMMING POOL Architects: Álvaro Siza Vieira Year: 1966 Location: Matoshihos, Portugal Leca Swimming Pool is an outdoor tidal pool. As seen in the image above, its change rooms are placed with in darkness.

This contrast of darkness of changeroom, and the brightness of the outdoor pool, is emulated within the project. The contrast highlights the openess of the pool and public, whilst the darkness of the changeroom brings an atmosphere of intamacy - the transition of brightness serves as a transition of space and purpose.

PRECEDANT STUDIES | 30

SHADOW.

31 | JURY FEEDBACK

As stated in the Leca Pool precedant, I attempted to create a contrast of lighting and shadow between the pool and the changerooms - to emulate a change from public to private. But as suggested by jury, the design of the changerooms - although cave-like, would be overly dark and not well ventilated. As such, I added pockets of skylights within the dark changerooms to architecturally lead the visitors attention towards specific functions, such as bathroom.

EXTERIOR RENDERING This rendering demonstrates the architecture situating within its context. The Shou-sugi Ban Louvres connects with the industrial background of the site, whilst the interior spaces intergrates with the preexisting site elevations. The tide pool is seen in the foreground at the location which existed the original pyrmont bathhouse.

Rain water is collected and filtered to be used in the Kid’s leisure pool. The water is then reused in the bathrooms.

Natural pond filtering, passively filtering the Olympic sized pool.

Harbour water is filtered, and used in the main pool. The water is constantly filtered through its natural pond filter, and the excess water is pumped out into the tidal pool, which inturn returns to the harbour.

MAIN INTERIOR RENDERING A visualisation of the interior view upon entry of the space. The rendering showcases the roof design with the fabric curtains, the Main swimming pool, the natural filter pond, and the direct pathway and view towards the harbour bridge and the tidal pool.

A PASSAGE TOWARDS WATER...

Play of elevation: A big element of the architectural design is within the slight change of elevation of the building as the visitor enters into the building, and towards the water.

As previously stated, the flow of space and splitting of pathways was designed to emulate a waterstream, at the same time, the visitor will experience various types of water experience as they walk towards the harbour themselves.

The various types of water includes: • • • •

Rainwater waterfall at the entrance Water stream towards kids pool Natural pond and still water Waves at the Harbour pool.

43 | visualisation

ENTRY LOBBY Upon entering the building, the visitor is met with a split of path between the cafe and the main pool space. The path towards the main pool is hinted with a waterfall, which drips and recirculates rainwater captured on the roof, which then slowly streams and filters through a natural pond, ultimately leading into the kid's pool. The visitor follows the path of the stream into the building, stepping down closer and closer to the harbour, alongside water.

Pool side A demonstration of the combination of materials apparent within the design. The ground is to be tiled with sandstone, calling back to the sandstone quaries background of the site. The Shou Sugi-ban wall is battened, and is extended from the exterior to within, to provide more contrast with shadow from the sky lighting. The battens are installed vertically, to provide a sense of verticality, drawing attention to the roof installation, and the pool below.

Tidal pool A tidal pool is designed at the location of the original Pyrmont Bathhouse. The tidal pool is accessed by swimming or walking under the preexisting timber platforms, which provides the pool a direct connection to the harbour water, and the harbour bridge. The tidal pool will mainly use filtered water which streams down from the main olympic pool, which will naturally inturn filter the harbour overtime.

Change room Main materials: Sandstone tiles ground, sandstone brick walls, corten steel sink, concrete celing.

Upon jury feedback, a skylight is designed at the furthest wall of the bathroom. By doing so, an element of gleam is placed within the darkness of the changerooms. By seperating the bathroom to the entrance with a piece of frosted glass, the sense of light highlights the destination to the visitors, and upon entry, emphasises the natural wall at the end of the passage. The skylight is to also provide ventilation for the changeroom whether through an operable window or ventilation holes.

53 | passive design

The glass roof, allows sunlight to enter the building vertically. By not allowing sunlight to enter from the side, sunlight can only directly enter from above. The light highlights the pool which situates beneath.

The 5 meter wide awning and walkway prevents direct sunlight from entering laterally, during both summer and winter.

Rain water is harvested through the slanted, directed into a gutter above the walkway wall, which is then brought to the entrance waterfall.

The building is passively heated through the green house effect, the hot air naturally rises to the tallest point of the roof, which is then collected, and redirected to the opposite side of the building. More details were shown within the detailed diagram.
