Can You Extend a New Build Home?
Buying or living in a new build house doesn’t mean you can’t extend the property. Many homeowners assume extensions are only possible on older homes, but with the right planning and advice, you can absolutely increase the space in a new build with a well-designed extension or loft conversion.
Permitted Development Rights on New Build Properties
One important thing to note is that many new build homes have their permitted development rights removed when planning permission is first granted. This means that you won’t automatically be able to build certain types of extensions (like a rear extension or loft conversion) without planning approval.
In these cases, any changes to the property must go through a householder planning application. While this adds an extra step to the process, it doesn’t mean you won’t be able to extend – it just means careful planning is required.
Restrictions You May Encounter
Depending on your property’s location, there may be additional considerations:
-
Flood zones – In some areas, extensions are only allowed under permitted development. If rights have been removed, this could limit your options.
-
Green belt land – If your home is in the green belt, the original developer may already have extended the property up to its maximum allowance, which can restrict further additions.
-
Design limitations – Local planning authorities may place conditions on how large an extension can be, or where on the plot it can sit, to ensure it remains in keeping with the area.
