Delivering Detailed Home Extension Plans in Hampshire

If you’re planning an extension or new build for your property, the best support is available from Architecture & Planning Southampton Ltd. Our experienced architects are on hand to throw the weight of our knowledge and experience behind your home extension project in Hampshire, from drawing plans to securing planning permission from local authorities.

An extension is the easiest way to add extra space and value to your property. Now is a good time to build an extension because the planning laws have recently been relaxed so you can have permission to build up to a 6m rear extension under your Permitted Development rights.


After we survey your property we aim to have your design completed and ready to submit within a week.
Feel free to call us if you need any advice on what you can build.

Planning Your Project

Ideally, we like to meet clients at the property in question first. After discussing your intended plans and measuring the existing layout, we draw up your ideas into a preliminary plan. This scheme is designed in accordance with the local authorities’ building regulations and we further develop it with your help.

Moving forward, we create a fully detailed design in the course of the next 7 days. Through careful design and choice of materials, we aim to keep your building costs at a minimum, while simultaneously making the most of the available space you have.

Next Steps

Subject to any adjustments or feedback you may have, we complete our design scheme and submit the plans to the relevant authorities for planning and building approval. We work closely with authorities such as Southampton Planning Department and maintain a high success rate in our planning applications for extensions and new builds.

Building regulations drawings may be required for larger jobs and we are able to produce these for an additional fee. If you don’t already have a builder in mind for your extension, we even forward our designs to a selection of suitable tradesmen and arrange for them to return a full written quotation.

On this job, both neighbours had already added 2-storey extensions, which increases the likelihood that you can do the same.
