Original Proposal

Lack Cultural Uses

It is believed that this will reduce the vibrancy and

diversity of the regeneration district.

Lack Direct Route to High Density Housing Development

Heavy Traffic in the Boulevard

The currently proposed boulevard is very much oriented for motorised

traffic which can hardly provide an enjoyable experience for the

pedestrians .

The tram line on ground that comes out from the central entrance

severely interrupt the pedestrian movement and other public activities.

The boulevard proposed has only a very narrow median strip.

The boulevard has only two rows of trees and benches. No details of how

drama is created are provided.

The Mayfield development has proposed a central green space that has a flooding zone, but within the

Piccadilly regeneration area (the northern side of the train station) gives no details regarding of this

issue.

Tram Line on Ground

Small Amount of Pedestrian Space

Lack Details in Creating Drama

Little Flood Risk Management

This will be inconvenient for the residents of that housing estate.

Cultural buildings and Amphitheatre Proposed

Diagonal Route Provided

Remain Part of the Traffic in London Road

Tram Line Underground

Much Widened Median Strip

More Thoughts is Creating Quality

More Flood Risk Management

The function of one another will be mutually reinforced. The public space will then be transformed to a hub of cultural activities and thus the function of the nearby section of the boulevard will be affected.

Other than the access to the housing development is facilitated, the circulation towards the northeast of the regeneration area will be enhanced. This layout of route system will strengthen the role of the cultural area as a central public space which is just outside an entrance of the future train station.

This will reduce the motorised traffic in the boulevard, so that a better space for pedestrians can be created.

The section right outside the train station is proposed to go underground and come out to the ground level again at the existing opening of the tunnel.

The median strip is now widened to accommodate stalls and varieties of green spaces.

A great variety of spaces will be created through planting design, e.g. from formal to informal; from open to intimate.

A large portion of the surface within the boulevard will be permeable to water. In front of the western entrance, there is a feature rain garden and by the lobe of the River Medlock in the new park, there will be wet meadow which can be flooded.

Design Statement

The proposed HS2 station to the north of the existing Piccadilly Station has initiated a regeneration proposal for the district in which a dramatic boulevard is anticipated, yet the current proposal has not detailed how it can be achieved. In light of this, the project aims at providing a feasible, but imaginative option to fill the gap.

The design of this project is inspired by the fluid pattern of the trees in the Medlock Valley which creates a variety of spatial qualities, so the design intention is to capture these qualities through tree planting along the Boulevard. This project explores how different forms, densities and arrangements of trees can define space in public realm. Lowering flood risk of River Medlock and offering better pedestrian experience are also the wishes of the project.
