Financial help

A house extension can be financially draining. A second mortgage is the best way to go about this. Planning your expenses before applying for a mortgage would be best. All costs, fees, and expenses should be considered. You may need to move to another location while the building and renovation work progresses. This could also impact your budget. We are here to help you with your London house extensions and to improve your living space. 

Planning your design

If you want to know how your house will look after the renovation, you must create plans. Be mindful of your specific needs. Spending too much on large extensions is not a good idea if you have a small family. If you plan to sell your Home, a well-planned renovation and remodelling could increase the property’s value.

Legal work

Have you ever asked yourself this question- Do I need planning permission for a house extension? You will need the appropriate permissions for your house extension to be permitted. A qualified architect or builder should only grant permission. You may not be granted permission. There are some chances that you won’t be granted permission. We resolve this issue to provide you with more living space and your existing space. 

Expertise in Building

The architect is responsible for more than just designing the structure. To get permission, the architect must help you draw up the plans. You may have to approach the authorities with any modifications to your plan if permission is not granted the first time. Horns Construction can help you obtain permission. The architect from Horns Construction will work to limit the number of changes you can make without requiring permission from the building department.

Properly done house extensions are a great way to increase the value of your home and make room for a larger family.
