1) INTRODUCTION:
This design statement has been prepared to accompany a Reserved Matters Planning Application for a proposed new single detached residential dwelling on site adjacent to 10 Birchleigh Terrace, Onchan. This application follows the previously approved application in principle (PA 18/00111/A) and seeks approval of the details of siting, design, external appearance of the dwelling, internal layout, means of access and landscaping of the site.
2) SITE/LOCATION:
The application site is a parcel of land, formerly a residential garden associated with No.22 Birchleigh Close. The application site is now not associated with 22 Birchleigh Close. The site includes an outbuilding building. The proposal site itself adjoins 10 Birchleigh Terrace, at the end of the terrace to its east. To the north, the proposal site is separated from 22 Birchleigh Close by a service lane which serves Birchleigh Terrace. The southern/western side of the proposal site is bounded by Hillberry Road. The site itself adjoins the property at No.10 at the end of the terrace and on the corner where Hillberry Road/Avondale Road curves. The proposal site is within walking distance from the village of Onchan and its amenities and close to public transport links. The character of the area is predominantly of medium to high density residential development made up of detached houses, semi detached houses and terraced properties, these generally of a varied and mixed character.
The design of the scheme is appreciative of the requirement to demonstrate that the development will not be detrimentally impacting in relation to the following aspects; i) Visual impact upon the street scene ii) Impact on Highway Safety iii) Impact on neighbouring properties with regard to a) potential loss of light/overshadowing, b) potential overbearing outlook, and c) potential overlooking resulting in loss of privacy.
With regard to i) above (Visual impact upon the street scene); We consider that the scale and mass of the development is comparable with the adjacent developments. The architectural style, detailing and finishes proposed is influenced by those prevalent on Birchleigh Terrace. The building line being set back from that of Birchleigh Terrace ensures that the development does not compete with nor be overbearing upon the existing terrace. The proposed dwelling is well designed with and finished with adequate amenity space, creating a property which, it is considered will sit comfortably within the context of its surroundings.
With regard ii) above (Impact on Highway Safety); The proposals cater for the provision of on-site car parking accommodating a minimum 2no cars with adequate turning area. Additionally, visibility sight lines will be provided to meet the required standards of the Department of Highways. There also exists a footway linking the proposal site to the village and its amenities. Therefore there will be no detrimental impact on highway safety.
With regard iii) above (Impact on neighbouring properties); The proposals have been carefully designed so as to prevent any loss of light or overshadowing to adjacent properties. The rear building line of the proposed dwelling matches that of the main part of 10 Birchleigh Terrace, All principle rooms face south/west and only bathroom accommodation at first floor level, which will be fitted with obscure glass faces neighbouring properties at an acute angle. The height of the proposed dwelling will be incrementally higher and comparable with the Birchleigh Terrace height increments to suit the topography of the site. The demolition of the existing outbuilding on the site will aid in reducing any existing visual/overbearing impact upon 10 Birchleigh Terrace. We consider that there will be no detrimental impact on neighbouring properties.
The proposal has been designed to provide a family home. The ground floor has been planned around a central open plan living, kitchen and dining area with all principle rooms facing south/south west. 3no bedrooms have been provided at first floor level again all facing south/south west. Circulation spaces and bathrooms have been located on the north wall. Hard surfaced car parking is located behind the building leaving the southern remainder of garden as lawn.
The proposed dwelling's orientation is critical in maximising natural daylight penetration and opportunities for solar gain in order to save energy, and to ensure that the quality of the spaces can be enjoyed as comfortably as possible. The layout of the dwelling has been designed to preserve the privacy to occupants and neighbouring properties. The principle living areas south \& south westerly aspects over the roofscape towards the sea and Douglas Head will provide excellent natural lighting throughout the day.
A carefully selected simple palette of materials has been chosen to match that of the adjacent terrace. White smooth rendered walls, upvc framed vertical proportioned windows on substantial concrete sub sills and the roof will be of natural slate or approved imitation slate. The fascia boards \& soffits will be of upvc. The rainwater goods to be black upvc.

The new dwelling will be highly insulated with improved airtightness to reduce heat loss. All windows will be minimum double glazed windows with u-values to exceed current Building Regulation standards, further reducing heat loss.
The new dwelling’s orientation is critical in maximising opportunities for solar gain. The layout of the dwelling has been planned in so far as is reasonably practicable to preserve the privacy to occupants and amenity areas of the proposal and adjacent properties. The main living areas are south/south west aspects will provide good natural lighting throughout the day.
The building will be afforded a highly insulated and airtight external envelope to keep the energy consumption for heating to a minimum by providing low levels of air leakage and improved element U-values.
Included within the fabric specification will be a high standard of thermal insulation to ensure that the energy requirement for heating is reduced. A log burner is to be installed and a high efficiency oil fired condensing boiler will provide the heating to the new dwelling via a wet underfloor heating system and in combination with any renewable technologies incorporated will guarantee acceptable midwinter temperatures. The super-insulation and high levels of air tightness will provide a healthy and comfortable living environment.
The following applications are relevant to this application; PA 18/00111/A
The proposed dwelling has a nett internal floor area of 113.6m2 and a footprint/ground coverage of 72.8m2. The site area extends to 286m2. The front building line is comparable with the adjacent terrace.
Foul and surface water drainage will discharge to the existing public sewer adjacent in accord with the requirements of the Manx Utilities Authority Drainage Department.
Mains electricity, water and telephone is located and available immediately adjacent to the site.
11) CONCLUSION:
The proposal seeks to provide a quality family home with associated parking and will preserve and enhance the character and appearance of the local area. The design, layout and density of the proposed development has been carefully considered in relation to the site's characteristics, the surrounding area and the relevant planning policies.
The proposed development is seen as acceptable for the following reasons:
1 - The scheme provides a quality family home that aims to preserve and enhance the character of the area through the appropriate design, layout, scale and mass; 2 - The orientation and layout of the proposal sympathetically relates to the neighbouring properties, and the overall character of the area; 3 - The proposal promotes a sustainable form of development in terms of clear design principles and construction methods; 4 - The proposed development offers high quality design by blending the use of traditional and clean forms, high quality materials and sensitive massing, both relevant in terms of design and reflective of the character of the area; 5 - The scheme offers satisfactory vehicular access. It is considered that the proposal represents an opportunity to provide a quality family home that is energy efficient in a sustainable location, enhancing the character of the area.
