1.0 Intro

Early Concept Drawing

City of Hedges, Euston Eco Roof Garden The project sets out to improving current Euston station infrastructure, by providing a new garden space for temporary relaxation and contemplation in a busy city. The early narrative looks at how to break up urban commuter’s stressful daily routine (which is a cycle of home-train-work-train-home) by providing an instant resting place and allowed commuters to escape from urban chaos and stressful life.

Hedges are used to recall different types of English gardens in several destination cites, and also create relaxed space in the current busy station, it is treated as an part of architectural material to providing shelter, insulation, and acoustic an buffer.

The design follows current planning policy to create a better architectural environment on different levels in Euston area. The whole scheme will replace existing structure, and the new structure which is a grid beam system + Y columns as part of station refurbishment.

The focused section is Section 02: Building Construction

1.1 London Commuter Issues

Statistic Shows: - Average UK Commute is 54 Minutes - Londoners have longest commute in the UK at 74 minutes almost twice the worldwide average - Most people hate commusting according to research.

- Commuters are at risk of injury Commuting is part of the everyday experience of Londoner.

In recent years the number of people commuting from home to work has risen. With it commuting became more stressful.

1.7 Hedge Gardens

1. Hedge Maze Hedge maze is an outdoor garden maze or labyrinth in which the "walls" or dividers between passages are made of vertical hedges. Initially, the hedge maze was not intended to confuse, but to provide a unicursal walking path. In modern times, hedge mazes have increased in complexity.

Eco Chimney

Ramp

The Eco Chimney are enviornmental filters providing the best possible air quality for platform & rooftop level.

Main access route from existing station fore court to the roof garden.

The ramp features hedges to introduce the commuter to the spaces above.

Lobby & Water Pavilion The Pavilion provide temporary rest for commuter, it is made of glass structurewhich holded by steel frames.

The lobby worked as reception to the rooftop level.

The canopy is transparent feature to give glimpse the roof garden above, and bring natural light to the station.

Solar Lighting TUbe The solar lighting core harvest solar energy to illuminate the station.

2.0 Structure Plan

Revision of initial structural layout in structural design meeting with Atelier One Structural engineers.

32

In rooftop level, the whole structure worked as a deeper truss system regarding to the tension and compression issues.

In Station level, the structure principal looked at Stansted airport; the tree columns are used for holding the heavy load from rooftop.

2.1 Structure Strategic Diagram

33

2.2 Structure Concept Diagram Option A: Arched Truss

Arched truss was considered for efficent way to resolve the tension and compression issue, however, it is hard to incorporate with tree column in station level.

Option B: Cross Braced Truss

Cross braced truss was considered, but the cross brace blocked pedstrain route, and interrupt building programs.

Option C: Verendeel Truss

The Verendeel Truss (Option C) is selected to allow un obstructed cirulation within the structure of the roof.

Fig 1: Tree columns holding beams

Fig 2: I beams in rooftop level

34

2.3 Truss Joint Study

Option 1: Cross Braced Truss Due to Tension and Compression issue, the Cross Braced Truss Option is considered, however, the cross blocked pedestrain circulation.

Option 2: Verendeel Truss Option The Verendeel Truss employed rigid joints, it fixing the conners of column and beams, and allowed pedestrain circulation through structure, therefore the option 2 is prefered.

35

2.4 Tree Branch Joint Study

There are totally 50 Tree columns, therefore 200 piece steel legs and 800 branch joint needed for whole scheme

03 BUILDING PERFORMANCE

The enviornmetal design of the ' city of hedges' was conceived as a envioenmental filter to improve the currently inadequade conditions of Euston station.

The design of a new roof structure allowed for a fundamental redevelopment of the entire station level. The main stratgy is to provide a filter which benefit both the station level and roof garden level.
