A two storey side extension is probably the best way to increase your living accommodation. A double storey extension will add both living and bedroom space, and when a side extension is used, it won’t cut into much needed outdoor space. As long as you have the exterior space that you need, a two storey extension is an excellent idea that will prevent you from having to search for a bigger home.
The cost of adding a two storey extension can vary depending on where you live. Once outside of London the price per metre squared will generally be the same. But, the addition of a kitchen or bathroom, or luxury fittings can quickly get the price spiraling out of control. But, on the plus side, the more room your home has, the more resale value it will have. A double storey extension will not cost double that of a single extension. So, it is the most cost-effective way of expanding your home. A two storey side extension will have the same foundations and roof as a single storey one; so it is easy to see why the cost will only be about 50% more.
Two Storey Side Extension : Will I Need Permission
Many house extensions can be built under permitted development rights, without the need for planning permission. There are however some restrictions that you should bear in mind when planning your project. When you use tradesmen recommended for you by BBN you can rest assured that your two storey extension plans will be totally legal and above board. For example, the roof of your new build cannot be taller than the highest point of your existing roof. If you wish to build without planning permission, your new extension cannot be more than 3m from your existing rear wall and no nearer than 7m to your property boundary.
Although you may not need planning permission for your extension, you may need permission from your neighbours. If you share a boundary wall with your neighbours, then you will need their formal consent. If you fail to adhere to the Party Wall act, civil action can be taken against you, and you may be forced to remove any completed building work. It is therefore extremely important to ensure that permission is applied for before work starts.
When adding a two storey extension, you can opt for a rear or side extension. You will not be able to extend out the front of your property. Where you choose for your extension will depend on how much of your garden and other outdoor space you are prepared to forfeit. When opting for a two storey side extension, you will be far more likely to encroach on your neighbours boundary and limits. However, a formal agreement can usually be reached to ensure that building work can go ahead according to plan. A well-planned extension on two storeys will provide you with much–needed space for your family home.
