This Planning Design Statement relates to the proposed creation of 4 No. light industrial units at Plot 1 'The Paddock', Jurby Industrial Estate, Jurby, Isle of Man.
The site was subject to previous planning application PA 19/00656/B. Three sides of the site are bounded by trees, providing natural screening from the A10 (main Jurby Coast Road) and the A14.
Industrial units are located to the east with partial screening provided by existing trees and planting.
The topography of the site is generally flat with a gradual slope running downwards from north to south providing a difference in level of approximately 300 mm .
Access to the site is from the existing industrial estate and utilises the new road constructed under the Approved Application for new light industrial units PA 05/00/243B.
The proposed development consists of one block with four light industrial units each with a calculated internal floor area of 104 m 2 (minimum 100 m 2 design requirement). The proposed units also offer a facility for future tenants to construct a first floor mezzanine area
over approximately $50 \%$ of the ground floor area, bringing the total potential floor area to approximately 640 m 2 . The Planning Application seeks approval to construct approximately 640 m 2 of Light Industrial floor space, however it is proposed that the Department will only construct 416 m 2 (the footprint of the four individual units) initially.
The new units will utilise the existing concrete road for access to Industrial and Personnel doors, and to the proposed car parking.
Car Parking: The proposed development will provide 22 formal car parking spaces in addition to forecourt space to each unit, which will provide for parking of larger commercial vehicles, in addition to providing space for deliveries etc.
The car parking is calculated as follows: Main Floor Area 416m2 Parking Ratio - 1:30 (car parking spaces per m2 of floor area) Potential Future Mezzanine Space - 224m2 Required Parking Spaces - 14 Spaces The Application assumes that the potential future mezzanine space is also designated as 'Light Industrial' for each unit, so an additional 8 spaces are proposed, to be constructed as part of the development.
The parking provision includes for $2 \times$ Disabled driver spaces. External Works: All the industrial units will be constructed with a concrete forecourt and a secure concrete yard to the rear, which backs onto the existing wooded area. A gravel footpath will provide access to the rear yards.
Access: Individual units have insulated roller shutter doors for deliveries etc. and separate glazed pedestrian doors for staff and visitors. The pedestrian door and glazed screen to each unit will be protected by a concealed roller shutter to improve security when the premises are in use. Rear exit / fire escape doors will be secure insulated steel doors and frames, finished with a factory applied paint finish.
Facilities: The floor areas of the units are approximately $104 \mathrm{~m}^{2}$. All units have a clear ground floor area unencumbered by structure, with space for a disabled toilet and drainage point for a kitchen/tea point, to be provided by incoming tenants as appropriate.
The Light Industrial units have been designed to facilitate the option for incoming tenants to construct a mezzanine floor which would provide an additional operational or storage area of approximately $54 \mathrm{~m}^{2}$. The proportions of the building and location of rear fire escape doors would support the installation of a straight access stair to the mezzanine level which could be fitted with a disabled person's platform wheelchair lift should there be this requirement.
Construction \& Building Fabric: The industrial units will be constructed utilising a steel portal frame structure, to provide the maximum usable floor area and achieve the floor to floor heights required.
The external walls at low level will be concrete cavity blockwork construction with a facing blockwork outer leaf, or rendered blockwork with a masonry paint finish. Insulated profiled metal wall cladding panels are proposed above the blockwork.
Insulated metal roof panels have also been proposed for the roof with integrated clear roof lights at a pitch of $10^{\circ}$. Colour matched metal rainwater gutters and downpipes will be installed to the front and rear elevations to collect rainwater and direct this to the fire storage tank and soakaway.
The design proposals include for the units to be constructed to meet or exceed current Isle of Man Building Regulations requirements, and detailing will seek to minimise heat loss through air leakage and cold bridging. The proposed wall and roof panel system will incorporate seals as per manufacturer's details to provide airtightness well above the minimum requirements of current Building Regulations.
The roller shutter doors and steel personnel /goods doors are also insulated to meet or exceed current Building Regulation requirements. All door and shutter openings incorporate seals to deliver weather tightness in a closed position.
Fire: The design proposals include the installation of a new 46,000 litres ( 41,400 litres useful volume) underground water storage tank which will be connected to the surface water drainage system taking rainwater from the roof of the new units, with an overflow to a soakaway system. The system will provide an additional source of clean water for the Fire Authority to fight any outbreak of fire in the Paddock area (as well as providing an additional resource for the rest of the Industrial Estate and wider Jurby area.)
Grass \& Landscape Areas: The design proposals recognise the request from DEFA that the existing turf from the site of the new units should be professionally lifted and re-used within the existing estate because of its unique natural characteristics. The areas of the site noted as 'grass' will be turfed using where possible, the original turf from the site. Areas of grass disturbed for the installation of drainage and the proposed fire tank will be remediated in a similar manner where possible. The setting out of the proposed development has been considered so as not to require any loss of the established tree planting to the rear of the proposed units.
The following finishes are anticipated:- Roof: Insulated roof panels with double skin matching profile roof light system. Walls: Blue Engineering brick plinth with facing blockwork or rendered blockwork with a masonry paint finish at low level, with insulated metal faced cladding panels above.
Insulated steel security doors to rear elevation: Mid / Dark Grey Industrial doors: Mid / Dark Grey Aluminium doors, frames and side screen to front elevation: Mid / Dark Grey. Rainwater Goods: Colour matched to insulated cladding panels.
