GROUND FLOOR PLAN
The aim of this project is to provide an interactive learning experience on renewable energy as a replacement of fossil fuels through a sustainability pavilion – a Rehabilitation Centre with traditional Korean sauna rooms as an adaptive reuse of heritage-listed Metropolitan Colliery in Helensburgh.
The mission is to refocus the town’s industrial development; revitalise the local community and; reduce waste and carbon emission in both construction and energy production.
It’s a lifestyle facility as an metaphorical journey of how geothermal energy as the substitution is being generated and how its by-product can be used to operatethe centre.

FIRST FLOOR PLAN
The proejct proposes an adaptive reuse of a heritage building at an existing colliery, so visitors can feel the transition and changes moving from coal mining. The project includes 3 sauna rooms of different temperatures and a lagoon in the internal courtyard.

In summer, the charcoal room minimises absorption of heat during the day with the angle of wall and having no openings on the north. whereas during the night, the heat is removed through the opening to maintain the temperature so it is also usable during the night

The Sydney Olmypic Park Wetland and Aquatic Research Centre project aims to create a discovery centre that reposnds and adapts to the climate changes and create a pivotal point for public and nature of the Sydney Olympic Park. Ispired by the extensive root systems of aquatic plants, it presents underwater abience and blurs the notion of inside and outside, sets up a clear entry point for the Newington Amrmory site.

Newingon Armory presents some of the most significant ecological system within Sydney Olympic Park region. The Park contains the largest remnant of coastal saltmarch in Parramatta River estuary where the largest remaining stand of Grey Mangrove and ohter marine vegetatios are protected.

The project envisions to create a prototype that imposes tranquil and sublime under water spatial quatliy composed of complex root system of aquatic plants. The irregular forms of roots intersect at different levels generating more dynamic appearance.
rammed earth
Final Proposition Exploded Axonometric View The biodiversity of the park include endangered native plant and animal species that require protection especailly on their habitats under threat due to destructions of their habitat and changes in nature and ecological systems.
The concourse of the metro is directly linked to the Hume park through the ramp. There is Clark Street between the metro site and the Hume park but as visible from the section, the ramp is bypassing the road by going beneath. The safety and accessibility through the mainstreamed passageway provide enhanced comfort and the ramp further dictats the design.
With introduction of metro proposal in Crows Nest area, the project delivers a solution for a urban revitalisation of the area for the existing community and future occupants through the design of public and residential complex situated on current Crows Nest metro construction site. The priority of the project was to create a seamless transition to the metro to the Hume park, creating a district of its own. Through the use of open footpath, we have provided a transparent locale which we aim to provide comfort through the familiarity of the landscape for the occupants.
The concourse can be accessed from the ramp, escalator, and lifts from the ground level of the site. The occupants can then further take the escalator down to platforms. The standard underground metro depth in Sydney is 25m and to keep to the standards, the concourse is 10m in depth and platform is 15m below it.

case study Cultral and Sports Centre Bruther, Paris The Cultural and Sports Centre is a public community building that provides a multitude of spaces that can accommodate varying purposes and needs. The concrete structure carries a series of free floors, distributed by a core. The transparent cladding allows the concrete structure, with its distinctive diagonal bracing system, to be seen from outside.
Canary Wharf Crossrail Metro Foster+Partners, L ondon The Crossrail Metro stations over site development were complete in the year 2015 and the metro station was due to be done 3 years after. The metro was delayed to late 2019 and now presumed to be pushed back further due to financial difficulties. There are up to four levels below water, level -5 being the metro platforms but due to it being still under construction, Plans are not available.

This is a collaborative project in a group of four students to present the understandings on construction and structures of a tower. The purpose of the project is to design a high rise commercial buidling at Barangaroo site which comprises of 60 floors and podium spaces which present the structural rigidity and complex structural system of a tower with sustainable archtiectural strategies.

.According to the situation of the site, design as a narrow triangular form which can reduce the impacts of wind and has a low impact of shadows on the surroundings to the south of the site. Considered about the circulation, the site is dividing ground level to two parts to let citizens go through the Hickson road to harbour, attract more visitors.

The environmental scheme is about the atrium placed in the triangular shaped floor plate. A triangle-shped central atrium framed by two cores, provides a passive ventilation through the full height of the building.The atrium and natural ventilation achived by double skin facade system mitigates the sheerness and becomes crucial in delivering fresh air into the building. Additionally, the atrium brings natural light into office spaces and controls the thermal comfort of the interior.
The 1:10 detailed sectional model presents the incorporation of windwo wall system according to the curved nature of south-west facade with supporting columns positioned at an angle to accomodate the increasing dimension of floorplate towards the podium and lower office spaces.
