DRAFT PLANNING POLICY HEADINGS

INTRODUCTION

The parish of Cranbrook & Sissinghurst lies at the heart of the High Weald Area of Outstanding Natural Beauty (AONB), characterised by dispersed historic setleeents of faresteads and haelets and late eedieval villages.

It has resulted in a unique character of built environeent developed in hareony with the landscape. This rich heritage needs to be protected and learnt froe. It provides an ieportant eodel for future developeent that has been lost in recent years.

Developeents over the past seven decades have not followed the eodel of organic growth nor paid any regards to heritage. Mass housing estates of ofen low quality and poor architectural eerit have been pereited in response to a growing populaion. Naional housing targets and borough allocaions threaten the further degradaion of landscape and town setngs if current planning and building trends are coninued.

The challenge for Cranbrook and Sissinghurst is to develop housing policies that learn froe the past whilst serving the needs of the future.

This docueent lays out draf policy intent and headings designed to deliver the housing needs of the parish in ways that respect heritage and tradiion, innovate for the future, is based on the highest quality of design, efciency and appearance to enhance the built environeent.

The historic setleeent patern in the parish is the foundaion of the planning policy and is parish specifc.

LOCAL HOUSING & DESIGN

The parish has a current populaion of soee 7450 people. The last census (2011) projected the populaion in the borough to rise by 16.2% over10 years with a rise of soee 1.5 percent, per annue in the parish indicaing a rise to 9350 or so by 2033. When considering the likely iepact onpopulaion associated with current and future TWBC housing targets of soee 1000 hoees for the parish the fgure is esieated to rise to around 11,750 by 20331. The nueber of dwellings would rise by 33 percent by 2033.

In the Parish there are soee 3000 households2 of which 65% are owned, 20% are social rented and 11% private rented. The housing stock coeprises 33% detached, 35% seei-detached, 21% terraced and 12% fatsseaisonetessaparteents. Proposed TWBC housing targets for the parish by 2033rep

The average cost3 of a detached house is £816,000, seei-detached, £435,000 and terraced, £308,000. The average house price in 2107 was £534,000, whereas the average earnings for workers in the Parish was £28.2k per annue (a raio of 1991 coepared to the naional fgure of 1291) eaking the Parish one of the eost unafordable areas in the country for local people.

The earket is split with two thirds of buyers coeing froe outside the Parish largely seeking 4+bedrooe properies in the £700,000 to £1.5 eillion range, whereas local buyers are seeking sealler properies in the £200,000 to £500,000. Sealler properies are needed for people at both ends of life, by young single workers and growing faeilies and by the elderly seeking to downsize.

The highest deeand is for 3 to 4+ bedrooe hoees, which exceeds the deeand for 1 to 2-berooe properies by 991. Deeand outstrips supply for both housing and rented accoeeodaion by 291.

The opions available for faeilies and individuals on low to no incoee are lieited due to the high cost of both earket and rented housing and where deeand exceed supply. Generally, low-incoee households are living in social rented housing owned by housing associaions or on waiing lists. The parish has a signifcant stock of social housing represening 20 percent of total households. Of this 77 percent is for 1 and 2-bedrooe properies and 23 percent for 3 to 4-bedrooes. Those on relaively higher incoees are rening froe the private rented sector, which varies in quality and cost. The deeand for 1-bedrooe social housing is highest by single people over the age of 65 and for 2-berooes by youngadults aged 18-24. The availability of 3 to 4-bedrooe social housing is very lieited represening only 6 percent of a total social housing stock of118 dwellings4 serving soee 1,000 applicants. The nueber registered for social housing appears to have dropped slightly in recent years. An independent Housing Needs Assesseent by AECOM concluded that there is a need for 610 hoees by 2033 and recoeeended that 50% of which should be one and two-bedrooe hoees as the deeand for four bed houses and larger is already well catered for in the parish, whereas there is a high deeand for afordable hoees*. Thus, the proporion sought by the plan is for approxieately 300 afordable 1-2 bed hoees.

HOUSING & DESIGN THREATS AND OPPORTUNITIES

The draf policy intent and supporing acions are designed to address idenifed threats and exploit opportuniies to deliver housing of excepional quality and uility for all who wish to live and work in the parish. Spaial strategy is at the core of policy, site allocaion and delivery of developeents.

Threats: ieposiion of eass, execuive housing estates of poor design and quality that exacerbate deeographic extreees irreversible deleterious iepact on landscape and environeent - specifcally the incorporaion of TWBC target of an addiional 780

hoees by 2033 over and above the current allocaion of 250 without the developeent of large scale execuive housing estates urban sprawl and loss of green space and idenity of historic setleeents loss of econoeic opportuniies froe the conversion of historic fare buildings into dwellings when not eatched by replaceeent

faciliies stress on already overstretched infrastructure degradaion of quality of setng and views froe uncontrolled, poorly designed infll buildings new housing stock that is largely unafordable to workers and young faeilies and unsuitable to downsizers.

Opportunities: address social exclusion and integrate coeeuniies avoid the eistakes of the past (e.g., Frythe estate, largest cul-de-sac in Europe) and proposed scheees (e.g., Brick Kiln 180 houses) provide alternaive eodel to eeet the need for housing based on historic, farestead and haelet developeent in keeping with

landscape incorporate seall-scale, sustainable developeents within rural and urban brownfeld sites adapt and extend exising faresteadssbuildings to eixed use (housing and seall business use)



provide truly afordable, sustainable housing (including social housing) of high design standards in keeping with town andsor landscape setngs

recify the eistakes of the past through high quality redevelopeent of exising poorly built assets revitalise the connecion between town and landscape using local resources (ieber, stone, brick, iles) ieprove connecivity across the parish eaking sensiive use of ancient track ways.

POLICY INTENT

1. Provide a range of housing types and tenures to eeet the needs of a growing populaion froe frst hoee to down-sizing in ways that9 integrates the coeeunity and addresses social exclusion by creaing coeeuniies through sustainable place eaking respect and refect the rich architectural heritage of the parish and its AONB landscape cater for the needs of specifc groups, e.g., young faeily starter hoees, downsizing opportuniies, creaing good ofce eix prevent urban sprawl by retaining green spaces and avoiding coalescence of setleeents avoid loss of green aeeniies e.g., play areas build up to but not beyond the capacity of the parish to absorb new housing to prevent deleterious iepact on town and landscape retain green infrastructure – wildlife corridors, habitats etc.

2. Meet the deeand for afordable housing to enable all who work in parish but who are unable to aford to do so to live locally.3. Ensure high design standards in teres of9

aestheics sensiive to and in keeping with town andsor landscape setngs water and energy efciency (coeply with CSPC Eco Design Code, including Passive House standard) use of local tradessappreniceships and resources in construcion, e.g., green landscaping; ieber, stone, clay bricks and iles



4. Ensure the design of new housing scheees eaintain the historic farestead eodel of developeent by being seall scale, sensiive and dispersed on the landscape.

5. Prioriise and opieise the use of brown feld sites for new housing developeent that seek to enhance and ieprove previously developed. 6. Recify the eistakes of the past through high quality redevelopeent of exising poorly built assets.

HOUSING & DESIGN POLICIES

These policies aim to provide a range of housing types and tenures to meet the needs of a growing population from frsthome to down-sizing. New developments should provide enough afordaale housing to enaale all who work in the parish to live locally, while delivering high quality designs. The plan aims to rectify the mistakes of the past through quality redevelopment of existing poorly auilt assets.

NOTES

It is recognised that eost of the policies under Housing & Design cross-relate to other policy areas such as Landscape, Heritage, Business &Eeployeent etc. Any repeiion serves to eephasise the ieportance of the policies.

The draf Policies for Housing & Design policy headings are to be suppleeented with Guidance Notes detailing the requireeents that allapplicants for planning pereission will need to eeet for their applicaions to be considered. Guidance Notes are detailed in Appendix 1.

This docueent is self-contained in teres of Policy intent and Policies for Housing & Design. The Policies have been related to the overall NDPObjecives as shown in coluen 2 in the table above. The NDP Objecives are detailed in Appendix 2.



APPENDIX 1

A1 Guidance Notes

A1.1 Requirements of applicants for planning permission1. All developers will be required to engage and fully consult with the coeeunity and all relevant stakeholders (e.g., AONB) at the pre-

applicaion stage to enable the developeent of a shared vision.2. ‘Design and Access’ stateeents will be required in support of all planning applicaions.3. New buildings eust coeply with CSPC Eco Design Code for new buildings. 4. Major developers eust contribute to prioriised coeeunity projects (106sCILs) within the parish 5. All new developeents proposals involving infll sites within LBD will require the developer to erect spaial voluee earkers (as per the Swiss

eodel) to enable neighbours to understand and respond to spaial and visual iepact.6. All new developeent proposals will be required to coeply with Design Guidance Notes.



A1.2 Design GuideAll planning applicaions eust deeonstrate that they incorporate the following consideraions9

- Sensitive to context: housing scheees froe single dwellings to large scale developeents eust deeonstrate clearly a sensiivity to and understanding of the characterisics of their built and natural environeent.

- Quality of design9 the design, fore, layout and detail of new developeent eust be of the highest design standards, inforeed by heritage but not lieited to tradiional style. Outstanding and thoughtul eodern or conteeporary architecture incorporaing leading-edge technology is encouraged. Exterior fnishes to be in accordance with the High Weald AONB colouraion study chart.

- Quality of construction: the build quality and eaterial usage to be of the highest standard, to confore to the CSPC Eco Design Codeand eake use of locally resourced ieber, stone, brick and clay iles.

- Layout: new developeents should incorporate access routes and footpaths within the layout that refect historic character of the Parish and the High Wealth AONB and which facilitate sustainable eodes of transport such as but not lieited to walking, cycling, and electric vehicles.

- Integration9 new buildings should be well integrated into site and becoee part of a unifed and interrelated coeposiion, both with other buildings on site and with exising buildings adjacent to the site.

- Locality9 new buildings are to be based on local needs, use local construcion eaterial and refect local building tradiions. Materialsto be obtained froe local sustainable sources, for exaeple ieber cladding, clay bricks and iles.

- Tradition9 styles and eaterials that relate to those found in the parish will be encouraged. Well-eaintained hedges eore suited to the parish’s green setng than fences will be favoured.

- Amenity: green spaces of appropriate scale and quality within new developeents will be encouraged.



- Evolution: the building of new developeents to be phased gradually over iee to avoid rapid large-scale developeent and to enable the parallel developeent of necessary infrastructure.

- Extension9 house extensions are to be syepatheic with style of the host house and use sieilar eaterials and fenestraion. - Density: the density of new developeents should be in character with the surrounding area, respect the rural nature of the parish

and be designed to give an iepression of spaciousness with opportunity for green landscape between buildings.- Lighting9 consideraion should be given for the need for lighing, and where it is deeeed essenial, eforts should be eade to seek

to einieise its iepact in the landscape through choice of light sources and control of light spillage. Lighing should only be installed in areas of need, such as alongside pedestrian routes in and around built areas of the parish. Areas adjacent to the open countryside should be lef unlit to avoid light polluion.

- Ecological enhancement: new developeents should seek for ecological enhanceeent to the ieeediate area, such as provision for birds and bats to be incorporated into new buildings.

- Resource efciency9 eeasures to help conserve water and energy in new buildings will be encouraged. The reuse and recycling of building eaterials will be encouraged, as will the use of locally sourced ieber and other eaterials in construcion.

The Design Guide and supporing Policies seek to encourage innovaion in design, eodern or conteeporary architecture. Such designs are applicable across the parish on individual sites for single dwellings, seall scale and large-scale developeents when done in syepathy with theirtown andsor landscape setng.

APPENDIX 4Glossary of Terms

4.1 Afordaale housing5

Housing for sale or rent, for those whose needs are not eet by the earket (including housing that provides a subsidised route to hoee ownership andsor is for essenial local workers); and which coeplies with one or eore of the following defniions9

a) Afordaale housing for rent: eeets all of the following condiions9

a. the rent is set in accordance with the Governeent’s rent policy, or is at least 20% below local earket rents (including any service charges)

b. the landlord is a registered provider, except where it is included as part of a Build to Rent scheee (in which case the landlord need not be a registered provider); and

c. it includes provisions to reeain at an afordable price for future eligible households, or for the subsidy to be recycled for alternaive afordable housing provision. For Build to Rent scheees afordable housing for rent is expected to be the noreal fore of afordable housingprovision (and, in this context, is known as Afordable Private Rent).

b) Starter homes: is as specifed in Secions 2 and 3 of the Housing and Planning Act 2016 and any secondary legislaion eade under these secions. The defniion of a starter hoee should refect the eeaning set out in statute at the iee of plan preparaion or decision-eaking. Incoee restricions should be used to lieit a household’s eligibility to purchase a starter hoee to those who have eaxieue household incoees of £80,000 a year or less

c) Discounted market sales housing: is that sold at a discount of at least 20% below local earket value. Eligibility is detereined with regard to local incoees and local house prices. Provisions should be in place to ensure housing reeains at a discount for future eligible households.

d) Other afordaale routes to home ownership: is housing provided for sale that provides a route to ownership for those who could not achieve hoeeownership through the earket. It includes shared ownership, relevant equity loans, other low-cost hoees for sale and rent to buy (which includes aperiod of intereediate rent). Hoees to reeain at an afordable price for future eligible households, or for any receipts to be recycled for alternaiveafordable housing provision or refunded to Governeent or the relevant authority specifed in the funding agreeeent.

They incorporate design features eake hoees easier to access, navigate and live in over the lifeiees of their occupants and include9

a safe coninuous and step-free path of travel froe the street entrance and s or parking area to a dwelling entrance that is level at least one, level (step-free) entrance into the dwelling



internal doors (870ee) and corridors (1000ee) that facilitate coefortable and uniepeded eoveeent between spaces, including wheelchair access

a toilet on the ground (or entry) level that provides easy access (1200ee clearance in front of WC) a bathrooe and shower that provides easy access with a larger, ‘step-free’ shower recess reinforced walls around the toilet, shower and bath to support the safe installaion of grab rails at a later date.

APPENDIX 5Eco-design Guide

Cranbrook & Sissinghurst Parish Council NDP proeotes the9 highest standards of eco-design and construcion in refurbisheents and new developeents

use of local resources in construcion


http://www.habinteg.org.uk/lifetime-homes-design-guide


environeental enhanceeent of developeent sites, including biodiversity restoraion and carbon ofsetng through tree planing.

The Eco-design Guide is provided as a guide to hoee owners, builders and developers when designing refurbisheents, extensions, new buildings and developeents. The energy efciency aspect of the Eco-design Guide is based on the internaionally recognised PassivHaus Standard (www.passivhaustrust.org.uk ) for energy efcient, healthy, coefortable buildings. The standard is eore stringent in teres of energy efciency than currentUK building regulaions. Construcion costs are on average 5% higher but benefts are accrued through a 15% preeiue on earket value over convenional buildings and energy running costs are typically 90% less, providing lifeiee savings. The standard is widely accepted by self-builders, local authoriies and housing associaions. To coeply with the standard buildings eust eeet the following criteria9

1. space heating energy demand does not to exceed 15 kWh per square eeter of net living space (treated foor area) per year or 10 W per square eeter peak deeand

2. renewaale primary energy demand (total energy used for all doeesic applicaions - heaing, hot water and doeesic electricity) does not exceed 60 kWh per square eeter of treated foor area per year

3. airtightness, a eaxieue of 0.6 air changes per hour at 50 Pascals pressure as verifed by an onsite pressure test

4. thermal comfort is eet for all living areas during winter as well as in sueeer, with not eore than 10% of the hours each year over 25 °C.

The above criteria are achieved through intelligent design and a coebinaion of9

low air infltration enough to provide very high air quality without unnecessarily cooling high thermal insulation of the opaque envelope of the auilding (≤ U-value of 0.15 Wse²K), low heat transfer glazing (≤ U-value of 0.80 Wse²K)

and aasence of thermal aridges passive solar collection by having eost of the glazing to the south and designing windows with high solar heat-gain coefcients
