The concept was developed from the precedent research about experience of Japanese Onsen, how people relax and reflect in the natural hot springs. The Urban Oasis is like the paradise in the desert and an escape from the dullness of the concrete city and pressure from daily life by providing an experience of enhancement & meditation through the combination of nature and water.

Front View

The history and landscape of the site as a quarry provided a main concept to connect different part of the design. The contradiction between the regularity of height in layering and irregular shape of each layer posed an inspiration in creating large forms but small spaces for people of different group size. The “quarry form” was used in different part of the design, such as the Public Domain and Pools as the main theme.

The idea of relaxing was cooperated by introducing abundant vegetation into the design. Presence of vegetation strengthen the atmospheric sense of nature. Given that connection with greenery could help reduce anxiety and stress level, this could further create a space which is more relaxing. Plants are used as aesthetic attraction and porous visual barrier in the design scheme.

Size of platforms vary to accommodate different group sizes

Public Domain

The Public Domain is a general staircase that connects Jones Street, which is above the cliff, and Wattle Street for a better circulation flow around the site.

The staircase is a combination of 3 modules, the stairs modules; the seats modules and the platform modules. The design aims to provide freedom of activity over the Public Domain. Users could be holding outdoor parties, relaxing from the seats with the view of Wentworth Park or simply circulate through the stairs.

The Back of House for the pool is hidden under the mass to avoid visual obstruction.

View of Program Pool

Reception

The reception is double height, closed by solid walls and a glass wall revealing the original sandstone cliff context.

A threshold moment is created which the visual change from enjoying the interior program pool and structure to the texture of the cliff would signify the shift from public area into the pool area.

The ramp indicates the entrance of the pool area

Perspective - Terraced Pools The Terraced Pools are the main water and meditation spaces of the design. The design was innovated by an Onsen quote “Let the past drift away with the water”. The story works together with the idea of terracing. The user at the pool would be encouraged to sit facing the courtyard with trees, while the water would be flowing from the highest layer downslope to create such motion of water that washes the user from his back to his toes.

Perspective - Outdoor Pool

The Outdoor Pool and The Ancillary Water Space are two contrasting water experience in relation of water and vegetation, which the outdoor pool is a water spaces surrounded by plants while the ancillary water space is plants surrounded by water. Although they are in contrary, they shared the terracing element for their pool depth.

The Outdoor Pool is conceptually to mimic a journey into the forest. The pool is like a pond that is surrounded by trees and vegetation. It is isolated from the main structure and other spaces by the dense green barrier.

In opposite, The Ancillary Water Space is designed to have isolated plantation spaces within the pool, which is like islands in the middle of the ocean. The vegetation also acts as visual barriers when seen from the Wattle Street façade.

4 5 Guildford Aquatic Center The structure is designed respective to the precedent research of V-shaped panels trusses at Guildford Aquatic Center. Instead of using CNC cut Laminated Strand Lumber Panels as the trusses, the truss system in the design used beams and columns system. The choice of structure system is decided to mimic the branches of a tree, which is more connected to the theme of nature.

Besides, the down curving structure is responding to the up sloping terraced pool. The lowest point of the structure is at the same time the highest point of the terraced pool, which creates a sense of compression at the center circulation walkway.

11 Exploded Axonometric

Irregular placed transparent roof modules allow sunlight to penetrate the building. The shadow of the truss would project onto the terraced pools to create a dynamic natural lighting that gives an idea of sitting under a tree canopy during summer.

High Angle Sun

During winter, the sun angle would not be as high as in summer. The sunlight would infiltrate the building through the glass façade directly for passive heating. The structural bracing and columns would then be responsible for creating the dynamic shadow to the pool area.
