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.
