It is one of a series of documents produced by the City Council encouraging high standards of development and environmental quality in Bristol.  \nThe design guide has been produced in recognition of the visual and amenity impact that extensions can have on the quality of individual houses and the street scene in general. The document provides guidance to assist in the understanding and implementation of Policy B9 of the Bristol Local Plan 1997, and the general urban design policies B1-B7.  \nBristol Local Plan Policy:  \nB9 House extensions and alterations will be permitted provided they:  \n• respect the form, siting, materials, details and character of the original property and its curtilage;  \n• respect the characteristics of the wider area, particularly where the property forms part of a semi-detached pair, a terrace, or a formal street pattern;  \n• would not cause unacceptable harm to the amenities of neighbouring occupiers;  \n• retain adequate car parking within the site.  \nThe purpose of the des","cbCailr7HQsHHUqc","https://ap.wps.com/l/cbCailr7HQsHHUqc","pdf",1182355,28,"English","# 1.0 Introduction\n# 2.0 Residential Context\n# 3.0 Listed Buildings and Conservation Areas\n# 4.0 Householder Planning Applications\n## 4.1 Do You Need Planning Permission?\n## 4.2 Information with your Planning Application\n## 4.3 Public Consultation\n# 5.0 Design Guidelines\n## 5.1 General Points\n## 5.2 Inclusive Home Design\n## 5.3 Sustainable Design and Construction\n## 5.4 Alterations\n## 5.5 Extensions\n## 5.6 Alteration to Roofs\n## 5.7 Balconies and Terraces\n## 5.8 Garages and Parking\n# 6.0 Advice and Further Information\n# 7.0 Bibliography\n# 8.0 Glossary","[{\"question\":\"What is the purpose of Supplementary Planning Document Number 2 (SPD 2)?\",\"answer\":\"SPD 2 sets out council design guidance and expectations for house extensions and/or alterations, focusing on broad issues such as scale, height, massing, layout, landscape, and parking.
