Public Realm

Application Scheme

In order to address the amended building uses at groundfloor, particularly the introduction of the cultural auditorium, the public realm proposals have been amended.

The key areas that have been discussed and addressed are:

1. Reduce scale of planters North and South of Skipton Street to avoid restricting pedestrian movement

2. Create a more flexible space as part of the public realm for a programme of cultural events and removal of skylight to create a continuous paved surface

3. Reduce vehicle impact of Ontario Street and provide areas to allow spill out and animation

4. Improve gateway area at South of Skipton Street, to signal arrival and change in use

Skipton Street

Public Realm Development

The public realm is set to become a dynamic environment for events and cultural activities that also needs to facilitate the requirements of the retail, office and residential accommodation within the development.

A programme of events that take place at weekly, monthly and seasonal intervals will each have varying spatial requirements. As such, it is proposed that the majority of

Skipton Street is left clear of all street furniture and planting.

The will also help ensure that events will not inhibit pedestrian movement for all building users.

The key design development points include:

• two feature trees to ‘book end’ Skipton Street with seating beneath to create inward and outward looking spaces

• tree grove to south of Skipton Street to mark the transition from London Road to Skipton Street

• seating directs pedestrian movement towards the central activity area of Skipton Street

• the central activity area is free of all furniture creating a wide open space for events

• Ontario Street is treated as a wide pedestrian and cycle way; tree planting helps to create a pedestrian buffer and cafe spill out area activate blank facades clear routes through street main pedestrian circulation

1. central avenue; opportunities for cafe terraces, cultural events and access to public roof gardens

2. tree grove marking arrival space; light canopy trees and clear stems

3. clear north south routes

Planting areas are located along Newington

Causeway, as per the December 2015 submission. A new planting area is proposed along Ontario Street that helps define a cafe terrace / spill out space.

All of these area will provide seasonal delight and interest as well as enhance local ecology and biodiversity.

Planting to Skipton Street has been removed.

The planting areas are associated with tree planting and seating. They will also improve the pedestrian environment and help provide visual relief within the context of the wider area. Shade tolerant, herbaceous and evergreen planting will provide colour and textural variety throughout the seasons.

The planting palette has been simplified since the

December 2015 submission. The following species have been removed;

Acanthus spinosus

Liriope muscari

All other species are as the original December 2015 submission

Public Realm

Trees

Where possible, existing trees have been retained and additional trees have been planted to reinforce their contribution to the public realm. New trees are located to improve human scale, reinforce spatial composition, legibility and wayfinding. The trees will also help to mediate the scale of the building and assist in creating a comfortable environment.

All street trees are proposed to be small leaved Lime

‘Greenspire’ (Tilia cordata ‘Greenspire’) They have a conical, regular form and will be clear stemmed to a minimum of 2.5m to provide clear sight-lines beneath the canopy.

Following the December 2015 submission, a grove of Honey

Locust trees (Gleditsia triacanthos ‘Sunburst’) with its light open canopy, will create a striking feature at the entrance to Skipton

Street from London Road, helping to signal the pedestrian arrival into a different space.

Large feature tree species have been changed to Rebona

Elm (Ulmus rebona). These will be located at key nodes along

Skipton Street and the pedestrian island linking Skipton House with Eileen House. Its open, broad canopy will turn from a glossy dark green to yellow in the autumn.

Existing Trees Retained / Removed.

There will be 12 trees removed as part of the development;

2 category B, 9 category C and one category U.

Public Roof Garden and Office Terrace

No changes to the Public Roof Garden are proposed as part of this addendum.

A generator will be incorporated at the terrace level of

Building C which was previously provided in the basement.

The facade will match the building and planting areas will help address the extent of blank facade facing the terrace.

The seating areas have been amended to create areas for tenants to sit in groups of varying sizes and maximise views over the London skyline.

Temporary Cinema Screen

As part of the ability to maximise the cultural and events programming offered throughout the Site, the possibility of providing a temporary cinema screen on the public roof garden has also been explored.

The diagrams below illustrate the number of seats that could be accommodated as part of a managed event.

79 seats

84 seats

1. high level viewing terrace; direct access from lift lobby back to ground floor

2. cafe / restaurant terrace

3. quiet garden area; opportunities to sit looking in and framing views out

4. terraced steps

5. lower level viewing terrace and garden

6. platform lift

7. sky lifts from Skipton Street to the 15th floor

The planting for the roof garden and office terrace is based on a diverse herbaceous and perennial palette, providing seasonal variety and delight throughout the seasons. The planting is designed to reflect the ‘Montane’ environment described in the design narrative, using grasses and herbaceous plants to provide year round structure and enhance the journey around the garden area for the users.

Groupings of multi-stem trees and feature shrubs will frame views over the London sky line and help to create a sense of enclosure in the quiet garden areas.

Planting is zoned to maximise the impact of seasonal variety and creating groupings of colour for dramatic interest.

The areas of planting zones to the office terrace have been amended since the December 2015 submission, to take account of the redesigned planting areas.

Refer to original Landscaping Statement (December 2015) for illustrative planting zone information.

Residential Terraces

Play

The raised level to the ‘link building’ means that a large play terrace is created on level 8 of Building A (previously level

7 in the December 2015 submission). A level of residential accommodation has also been removed from Building A resulting in a reduced child yield, as shown in the calculation below.
