Planning Permission in West Sussex

Planning permission is an essential factor of any changes to your property. You can engage the services of an architect or architectural services firm to guide you through the process of securing planning permission for your home extension. Architects are experienced with submitting planning applications, and will have a good knowledge of the requirements and restrictions both nationally and in your local area. The majority of planning permission applications are granted, especially if you can establish that your building work is sympathetic to the conditions established by local authority policy. Architects can help with every part of your planning application, from producing technical and architectural drawings to submitting paperwork with your local authority. They are able to also ensure that your planned work is designed to a high standard, creating functional and aesthetically pleasing spaces that will suit your current property. While some alterations to your home are included in permitted development rights and as a consequence won't require planning permission, you'll still need to adhere to building regulations. Hiring an architect to draw up the plans for your extension will make sure that any work you carry out will conform to these regulations and be of a high standard.
