Tree, Flood, and Ecology Reports for Rear Extension Plans

When planning your extension, you will need the help of the experts from the outset. When you have a professional team working with you, you won’t be shocked when you receive more bills than you bargained for. If you need a tree report for your rear extensions plans to go ahead, this will cost you a minimum of 800 pounds. The same charge is applicable for flood risk assessment. An ecology report will also set you back 800 pounds. This may or may not be required by your local authority.

If the land you plan to build in is of archaeological interest, then an archaeological report will also be needed. This is not likely to be the case when you are simply building an extension in your back garden. This is good news, as this type of report can cost thousands of pounds. If your home is a listed building, then you will also need an historic building report before you can go ahead with your rear extension plans.

Planning Permission

In general, you will not require planning permission for a single storey extension to the rear of your home. If your plans are more ambitious however, you may need to apply for planning. This is something our experts can help you with too. If your extension covers more than half of the area of the land surrounding your home, you will need permission. So, if you have little front garden, and are planning to take up almost all your back garden with an extension, you will need planning permission.

You will also need to apply for permission if you are extending towards a road. This is unlikely when your extension will be built to the rear of your home. If you increase the overall height of your build you will also need planning. This would only be the case with single storey extensions when your home is a bungalow. A bungalow where the roof of your extension will be higher than that of your existing build. If you are going to extend more than six metres to the rear of a semi-detached or terraced property, you will need planning permission. This figure goes up to 8 metres when your property is detached.

How to Avoid Planning Permission

To avoid planning permission for a single storey extension, ensure that the build is less than 4 metres tall. Also ensure it is no more than half the width of your house. Avoid using materials that are different from your original build. Also, avoid adding a balcony or verandah to your plans.

The current price in England for a planning application is set at 206 pounds. This does not seem like a great deal of money. But it is a fee that you will pay each time you submit plans. So, to avoid having to submit plans on multiple occasions, ensure you use the services of a professional planner or architect. Your local planner we provide you with will be familiar with local planning authorities. He will know in advance what their preferences are.

Single storey extensions can also be built using permitted development rights. PD can be used for single storey extensions, as long as you do not use contrasting materials. The footprint of the extension will have to meet certain criteria too. If you choose to build with PD, you may also like to apply for a certificate of lawful development from your local authority.
