3 things you should know before investing in a house extension

Before deciding to extend your property, there are a few basic essentials of extension projects that every conscientious homeowner should be aware of.

House extensions without planning permission

Traditional house extensions offer plenty of flexibility when it comes to location and size. House extensions can often fall under permitted development and may not require planning permission. However, some of the more complex alterations, such as side house extensions, have a bigger impact on the appearance of the street scene and will need planning permission. The application needs to be submitted in advance and can take a several months to obtain the necessary permission.

This extension has created an additional lounge at ground floor level together with an additional bedroom, master bathroom and ensuite at first floor level together with an external dormer to the loft space. This was achieved by using reclaimed materials of matching colour and texture, paying particular detail to construction techniques and external finishes.

House extension or conservatory

Which is the best solution for you and your property? Most importantly, as a general rule, an extension will add more to the financial value of your house should you ever decide to sell it.
At a later date it may be possible to add a glass conservatory to your house extension (but rarely the other way around). In many cases, the total cost of adding a proper conservatory is cheaper than building an extension. However, whilst house extensions have to be fully insulated, heating a conservatory throughout the winter period can be expensive. Therefore, your running costs and heating bills will be lower with a house extension than with a conservatory. A free site visit from our building surveyor here at Craymanor Ltd will allow for a discussion to help you determine the best solution for you and your budget. The ground where foundations are to be laid may also be a source of additional material costs – poor soil may require deeper foundations for adequate support. Extensions built on clay soil tend to be less expensive unless there are large trees very close to the extension.

Addressing the floorplan: the practicality of a bathroom

If your house extension project includes at least one extra bedroom, it is sensible to allow for at least one full bathroom per floor. Larger households can benefit from bedrooms with en-suites (a full bathroom usually accompanies the master bedroom). House extensions are the chance to provide additional bedrooms according to the needs of your family, however this should ideally be balanced out by adding a number of bathrooms.
