Building an extension on your existing property is a great way to add extra living space to your home as well as increase its value. Extending your home is a popular way of adding more space to your property, so you don’t have to incur the costs of moving house.

There are considerations that need to be made before constructing an extension; the plans of your project need to be taken into account. Will it be single or double storey? Will it be a loft extension or built at the rear of your house? Does it have suitable road access? What is the surrounding land like? How is the soil condition of site? Financing the project is another important consideration. It is worth looking into using your home as a way to make money if you are worried about paying a potentially large sum of money on property building works.

The proposed project might need planning permission before it can go ahead as well as needing to meet building regulations. You will need to find out all of this essential information before starting any building. Finding an architect to help with design and building of your extension will normally ensure a much smoother project.

If your extension has been approved then you can start designing and building. Many people design their own build depending on the nature of their existing property, as well as their own living space requirements. This will determine whether you build up in to your loft, down into your basement, extend your kitchen out, or even build a garden room outside.
