1.1 Introduction to Site

Figure 1.1.2 Key Plan

Location of Project Jalan Stesen 1, Klang Building Function Learning Centre Plot Size 708.75mÂ˛ Figure 1.1.1 Site Plan Page 1

Jalan Stesen 1 is located in the old town quarter of the pre-industrial city of South Klang. The deformation of grid is highly dependent on the sinuous topography of Klang River and is evolved and developed through use, hence causing the misalignment of Jalan Stesen 1 in relation to Jalan Tengku Diauddin and Jalan Besar (refer to Figure 2.1.1). There are three main communities that are being identified: the Empathetic Insider who has a strong sense of attachment to the site and create the local culture and live in them for a period of time; the Existential Insider who exists because of the business opportunity that the town offers and forges the formation of Little India; the Objective Outsider who possess an attitude which effectively reduces the place to a single dimensional perspective as a direct consequence of their first time experience in the town.

1.2 Introduction to Architectural Design Studio Project

Figure 1.2.2 Design Intention

Design Statement Great places have historical weight, gravity of significance. They played meaningful roles in the townâ&#x20AC;&#x2122;s evolution, just like the old royal town Klang. Their stories are as palpable as the air, we can feel the ancient energies that are still there, which are currently in dormant state. Traditional businesses are forced to closed down due to lacking in pedestrian volume. To counter the issue, the learning centre takes a stance in instilling economical viability to the old town quarter while maintaining the local social memory to rejuvenate the townscape immediately. The learning centre programmes expresse plural attitudes towards the act of retaining the social memory of the places based on the behavior of the three main communities identified on site.

‘HHH’ House

Architect

Simple Projects Architecture

Location

Surabaya, Indonesia

Area

321.0m²

Built Year

2019

‘HHH’ house was inspired by our childhood memories and perception of a house to begin with. As a kid, we often picture a house with a single triangular roof (pitch roof) on top of a square wall with a door and a window, and we were inspired by these basic shapes and unpretentious materials used on the houses we have seen when we were young. A vision of a simple home with cozy ambiance is the space quality that we would like to offer.

Figure 2.1.5 In-situ Reinforced Concrete Page 3

Construction Process 1. 2. 3. 4. 5.

Construction Details - Floor to Wall

Metal decking acts as a permanent shuttering and spans in a direction transverse to the secondary beams. Primary and secondary beams in composite steel frames are rigidly connected to the floor slab by shear studs. Shear studs are connected to the beams by deck welding techniques, allowing the floor slab and beams beneath to act compositely. Steel mesh reinforcement is placed above the steel decking to provide bending resistance and reduce cracking at the supports. Concrete is casted in-situ.

Integration to Learning Centre 1. 2. 3. 4.

Due to its lightweight properties, the dimension of structural beam and column can be adjusted smaller which hence decrease the overall construction cost. Considering the narrow vehicular path to site, in-situ cast concrete construction is more suitable than pre-cast concrete construction. High structural stability allows minimal excavation and dimension of foundation which minimize the effect to the adjacent shophouses foundation. Flexibility in design to reduce the amount of structural elements (number of columns etc.)

Built Year

2012

The project consists of the complete redevelopment of a post-industrial brownfield into a public park and performance space. The idea driving the design is that the built elements are sculptural forms emerging out of the landscape of the park. The built elements include a stage with acoustic shell, a backstage with loading dock, green room and wings, a seating area, and a sound and lighting control booth.

Construction Details - Concrete to Timber

Existing concrete raft foundation is preserved and steel connections are added to it. Steel beams which are prefabricated off-site are connected to concrete foundation. The structure of timber bandshell walls comprised of prefabricated wood trusses and are modelled digitally. Timber flooring is being installed, followed by timber walls and then roof panels. Alpolic Metal Composite Panels are used to clad the underside of the bandshell and are digitally fabricated as well.

This project is a complex building of houses and galleries built in Tokyo, Toshimaku. One tree is organically integrated with a combination of parts having different characteristics, such as a trunk, a branch, and a leaf. As with the tree, we tried to create an organic architecture that could be formed by a hierarchical combination of different parts such as plants/pleats (as openings) / concrete boxes. We set up planting around the pleats and create an organic whole like breathing in the surrounding environment like a tree.
