3 Of The Biggest Things To Think About When Extending Your Home

Things to think about when extending your home

The various lockdowns over the last year has given us all plenty of time for reflection, and one realisation you may have come to is that you really need a larger home. 

When sharing your home for such a long period with a big group of family members, it can sometimes get too overcrowded, and you reach a point where you feel like you’re living on top of each other.

This leaves you with two possibilities – you either move to somewhere bigger, or you extend, if you have the room to do that. 

Extending won’t cost as much as moving, and it will be a lot less stressful when it’s organised with Hazlemere. But, there are some factors to be considered first:

Planning Permission / Building Regulations

If it meets certain limits and conditions, a single-storey house extension can be classed as a Permitted Development, meaning that it can be built without the need for planning permission. 

To clarify if a proposed extension complies with the required limits and conditions, contact the planning department at your local authority for guidance. 

Building regulations approval is an altogether different matter to planning permission. Again, there are some exceptions, but you’re advised to speak to your local building control officer for clarification.

Set a budget

How much are you prepared to pay for a house extension? What exactly can you afford?

Take a good look at your finances, and get out a calculator so that you can figure out a budget for the project. 

Once you have come to a figure, let the building company know and they can use this information to inform you of what you can get for your money and produce some design concepts.

Will it add a decent amount of value?

A house extension shouldn’t just add extra space. It should also add a worthwhile amount of value to your property.

How much value there is in building an extension can come down to a number of things, including where your house is located in the country, the size of the extension, and its overall build-quality.

An experienced extension specialist will probably be able to let you know how much an extension they have constructed at a similar property added to it, to give you an indication of what it could do for your home.
