SIR STANLEY MATTHEWS EXTENSION DESIGN + ACCESS STATEMENT DRAFT - REV B FOR COMMENT JANUARY 2020 // + 1 2 3 4 5 c Stoke on Trent City Council 2 // + 1 c Stoke on Trent City Council 3 // + INTRODUCTION This Design and Access statement is part of the information submitted for the Sir Stanley Matthews Academy building planning application. The statement address- es the evolution of the project and how earliest design principles and concepts have developed into the formal design proposals. The success of the Sir Stanley Matthews Academy has led to a substantial increase in projected pupil numbers over the next five years. Existing facilities are expected to become overly compressed and a need for additional rooms paramount. The new extension will provide an additional seven new classrooms, which includes two science labs, and so enable the school to provide places for an additional 150 pupils by 2025. As the project is located within the wider Sir Stanley Matthews Academy site, con- sideration is given to how proposals have been influenced by and respond to this location. Throughout this report the existing Sir Stanley Matthews Academy building is referred to as the main school building. Due to this connection with the existing school the lowest floor in the new extension is Lower Ground Floor, then Ground Floor and First Floor which connects with floors in the main building. Architectural proposals including details regarding the appearance, materiality and scale of the project are discussed in Section 03. Landscape elements of the scheme include the siting of the annex and existing + proposed routes around the site are detailed in section 04 of this report.

The Academy is a co-educational second- ary school located off Beaconsfield Drive in the Blurton area of Stoke-on-Trent. The school opened in 2010 and currently accommodates approximately 1100 stu- dents. The proposed extension has been designed to extend off the west side of the main building. This enables the site to be used to its fullest extent and also provides an opportunity to incorporate areas of the main building into this project. The site is bordered on the west by Kemball Special School and to the east by residential properties. Access to the site is primarily by car although a local bus service runs within close proximity. Across the wider site the existing residential building stock is primarily two storey red brick semi detached units. The Academy contrasts with this typography and is a mix of curtain walling, contrasting coloured cladding panels and brick. Proposals for the extension look to reference the main Sir Stanley Matthews school material palette and facade design.

There are minimal changes in level across the site and level access can be provided leading between the school and the extension. 1 // Looking from Academy down onto the site 2 // Looking from Academy across the site Existing Site Context The materiality of the Sir Stanley Matthews Academy offers a contrast to the red brick residential units that border the site. The use of a distinctive material palette reinforces the idea that the building serves a different function to the other building stock in the area and is clearly identifiable. The proposed extension references this material palette to ensure that it sits comfortably on the Academy site. However, the number of materials used is also restricted to ensure that the extension is a subtle and consid- ered addition to the site. 3 // Sir Stanley Matthews Academy 4 // Sir Stanley Matthews Academy c Stoke on Trent City Council 7 // + 3 c Stoke on Trent City Council 8 // + Reasons for Development The scheme responds to the need to provide essential additional space for the Sir Stanley Matthews Academy with projected students numbers expected to increase by approximately 150 by 2025. This represents an approximately 12% growth on current student numbers. The extension will create an additional 7 classrooms including 2 science labs and 2 flexible teaching spaces which will allow the school further options when arranging the teaching of the curriculum.

At roof level a section of pitched glazing will assist in dragging light down through the void spaces into the street. c Stoke on Trent City Council 17 // + BUILDING FACADE It is proposed that the South West facade of the extension incorporates clear glass and horizontal louvred windows. The style of the window mimics those found on the main building and will help to tie the extension back to the wider school site. The windows are divided into panels of 2 or 3 with louvred panels then further subdivided. Internally a back panel within the louvre section will be openable to allow for spaces to be securely and safely naturally ventilated. This in turn will allow for the extension to be naturally ventilated. 3. The rhythm of the window module is flipped across the building so as to intro- duced interest to the facade whilst the use of green glazed brick will introduce further visual interested when the school is viewed from the Kemball Special 2. 1. School site. To the North West and South East a linear section of clear glazed curtain wall- ing aligning with the internal stair landing is proposed. Both of these facades will be constructed of blue black brick to the lower ground level and vertical cladding panels. The North East facade is primarily formed from the existing school buidling. Where the facade does become visible it will again be constructed of blue black brick and cladding panels. 3. 2. 2. Design Intent The facade treatment was developed in accordance with certain key design 3. drivers: 3. - Regular bay modules that will provide adequate levels of daylight and ventilation. - The facade design should allow for future flexibility and should therefore function effectively even if internal room layouts are changed. - A colour palette which aligns with the main school building Material Key 3. 2. 1.

Facades The first floor of the extension will be clad with a restricted palette of different materials all of which are used on the main Academy building. Window Module The window modules are a combination of fixed clear glazing and openable doors behind louvred panels.

It is not pro- posed for any new waste store or external bin facility to be con- structed. Waste generated in the annex will feed into the main building waste bins. Existing routes around the site will be utilised to provide suita- ble paths leading from the extension to the bin store. It is not expected that any kitchen or specialist waste will be gener- ated in the building. Windows have been designed to mirror those in the main building and will incorporate a fixed glazed panel and an inwards opening door situated behind a fixed louvred panel. The opening door panel will be able to be cleaned internally whilst the fixed clear glazing panels will be cleaned by a pole system from ground level. As it is not expected that any windows will open outwards there is no need to provide any demarcation around the windows. . At roof level the strategy for cleaning the roof lights will be further developed. It is expected that a step over stair will be incorporated to the existing gym roof to allow access to the extension roof. Fol- lowing development of the design for the plant the position of this step over stair can be finalised. Around the roof perimeter a 1200mm edge protection formed by the external walls will provide suitable protection.

It is expected that Secured by Design standards will be incorporated into the project, where appropriate, as part of design development and that the ALO will be liaised with during detailed design stage. BREEAM It is expected that the Sir Stanley Matthews Academy Annex will be assessed for environmental performance against the BREEAM New Construction 2018. The building is classified as an Education development for this assessment. It is expected that a BREEAM Good rating will be targeted. A BREEAM Good rating requires a score of 45% or above, this is a Flood risk from rivers or the sea // feasible target for the development. It is expected that future steps https://flood-warning-information.service.gov.uk/long-term-flood-risk/map will involve the creation of a BREEAM Tracker to determine which credits will be achieved. As the design develops the design team will need to ensure the BREEAM requirements are incorporated into the detailed design to meet the targeted credits. More detailed analysis of energy perfor- mance, ventilation, daylight will be required as details are finalised. FLOOD RISK The proposed site is over 1 Hectare with areas of the site identified to be at a varying risk of flooding from surface water but at no risk of flooding from reservoirs, rivers ot the sea The annex is not a change of use in development type to a more vulnerable class Flood risk from surface water // https://flood-warning-information.service.gov.uk/long-term-flood-risk/map c Stoke on Trent City Council 25 // + 4 c Stoke on Trent City Council 26 // + ELEMENTS IN THE LANDSCAPE + SITING OF THE ANNEX The landscape proposals for the site are limited in scope. The ex- isting routes around the site will not be affected by the development with the extension tying in with existing levels. Extending off the existing west side of the Academy building creates additional space between the footprint of the new building and the boundary edge so as to ensure existing vehicular access routes can also be maintained. The existing gated entrance use by vehicles will be repositioned whilst a small area of existing grass will be rescultped to allow for the existing path to be widened locally around the footprint of the new extension. To the west side the existing light column will be repositioned - illumination would be directed towards the pathway with no light spill beyond this. The spread of lighting will be below the horizontal. Lighting lux levels would be the minimum standard necessary for safety and security purposes No additional parking or cycling facilities are proposed. Sir Stanley Matthews Academy 2.

As noted the proposed site connects with the existing building and levels around the site so that no new routes way are being created. Internally accommodation is split over three floors with WC facilities located on the ground. Circulation between the levels is via stairs or a lift. At ground level the entrance is located on the south east facade towards the middle of the facade ensuring that it is clearly visible. Alternatively the building can be accessed via a high level corridor that connects the extension and the main building. Around the perimeter of the building other doors are either fire exits or entrance to plant space and so it is not expected that they will generally be used. Final exits are sized to based on intended occu- pancy numbers. Internally doors lead off a central circulation route into the classroom spaces. Doors do not open into circulation routes and it is expected that they will incorporate vision panels and clear widths in line with AD K. The fit out of the WCs will be finalised during detailed design stage but it is expected that they will be in line with AD K. No showers or hygiene areas are proposed. There are two staircases to the building running from lower ground floor to the first floor. Each stair can be used for fire egress and will incorporate refuge areas where two way means of communication will be provided. A platform lift is also incorporated so as to allow for accessible circulation through the building. The lift will not be able to be used in the event of fire. Access to the roof will be via the main building with a step over lad- der leading from the main academy building to the roof of the exten- sion. A 1200mm high parapet will act as edge protection around the extension roof top. A man safe fall arrest system is proposed to the roof of the rooftop extension and the high level corridor as it is not expected that access will generally be required to these spaces. c Stoke on Trent City Council 30
