Development of the reference design into outline design

Cavern

• Piling works at night limited to only when essential

• Reduced utilities works in Park Village East

• No major rail disruption from closing Network Rail lines E and X

Euston Approach Tunnels

• Barrettes* not being constructed within Park Village East

• Reduction in major road closures in Park Village East

• Mornington Street Bridge no longer being replaced

Euston Portal

• Reduced footprint of above ground construction works

• No major changes from Reference design

Scissor Cut

• Removed the need of Barrettes reducing the potential disruption to local community

Throat

• Existing bridges not being demolished

• No major closures of Network Rail

• No temporary utility bridges required Changed utility diversion methodology to use Granby Terrace Bridge

Community concerns

You told HS2 that you were most concerned about:

• Safety of school children

• Noise, light, dust, vibration

and visual impacts

• Tunnelling and settlement

impacts

• Air pollution

• Impacts of construction

traffic

• The loss of areas of green

and open spaces

• Not retaining and re-

providing trees

• Impact on safe cycle and

pedestrian routes

• The design of hoardings

• High quality locally specific

architecture

• Nature and biodiversity

road/space for screening - visual impact reduced

Service areas inside the site

(not on the street)Single level head house – reduced

visual impact from Park Village East

What we did for Euston cavern head house

Walls replaced

Main construction access at rail level -

less traffic, less noise at Park Village East

Proposed materials and finishes

Our design experts have considered a range of materials that could

provide a consistent theme to the head house structures along the route

and still be used sympathetically at each specific location.

The current recommendation for Euston cavern head house, after

discussion with Historic England and Camden Council’s conservation

team is

• Predominantly brick with metal louvres to the railway façade

• Façade to Park Village East to be developed to be most sympathetic

to the historic John Nash villas

For the Euston portal head house and Granby Terrace Bridge head

house, we are developing proposals for a combination of these

materials. Please give us your views.

Reducing the visual impact of Euston cavern head house

“… sensitive design for site gates / ensure new structures are as unobtrusive as possible in proximity to listed buildings.”

Lorry movements and routes for construction

Predicted lorry movements

in the Environmental

Statement (ES) of 335-495*

average daily combined

two-way vehicle trips

during busy period and

within peak month of

activity.

*Combined ES lorry movements

for compounds, Granby Terrace

overbridge and carriage shed

and Park Village East

We will aim to reduce the

number lorry movements

in the Euston area to below

the ES predictions, working

closely the other HS2

contractors and with TfL

and Camden Council.

What we’d like to know

How to get in touch

How you can help

We have employed expert designers to develop a design that minimises impacts where possible, and have proposed materials that we think best suit your local area. Now we’d know really like to know what you think about our proposals.

There are questionnaire leaflets for you to fill in here or to take away, and they will be available online too. Please take some time to fill one in.

We will come back in a few months time and tell you how we have used your feedback.

Please leave your questionnaire in the ballot box near the door, or return it to: FREEPOST SCSRAILWAYS

Alternatively, please email it to [email protected] can also obtain the questionnaire form the website. Please submit by 12th August 2018.

We will also make event material available on the HS2 in Camden website soon.

If you have any additional queries after the event, please contact the HS2 Helpdesk on 08081 434434.

Our Questionnaire asks for your views on these specific issues:

• The changes made to design for the overall area (boards 1 and 2)

• the materials we are proposing for the outside of the Euston cavern head house (boards 4 and 7)

• Possible materials we are proposing for the Euston portal and Granby Terrace Bridge head house (boards 5 and 7)

• the proposals for planting of trees and other vegetation for screening (board 8)

• the appearance of the site access gates on Park Village East (boards 8 and 9)

• Any concerns or comments regarding the lorry routes into and out of the site (board 10)

But we would also like to know what other concerns that you may have. Please use the space on our form to give us your feedback – it is very important to us.
