FAQs

Can an extension add value to my home?

Yes. Most extensions will add substantial value to your home, and you may find that the extension adds more value than it cost. However, it’s important to be sure that the home remains balanced. Extending your garage and leaving your property with no parking spaces, for example, may impact your ability to sell.

What types of extension are there?

There are many different types of extension. For example, you could install an orangery, flat or pitched roof extension, over-structure extension, single or double storey extension or a glass box extension. Which one of these is most suitable will depend on your existing property.

how big can my house extension be?

The holy grail of home extensions is basically the need for additional space for living as well as leisure. However, before commencing your home extension project, you’d probably want to know just how big your new building can be. In this article, you’ll find the answer to this question which is also frequently asked by many other home or property owners in the UK.

Besides your budget, there are two other major influencing factors that can determine just how much extra room that can be added. These factors include whether you wish to carry out the extension project under Permitted Development rights which is usually for a smaller project or you’d prefer to opt for a larger project which is covered by Planning Permission.

Apart from the limitations in the size of an extension under Permitted Development, the extensions are also a lot more affordable and consumes less time when compared to the extensions under planning permission. So what exactly is the size limit for an extension under Permitted Development and the ones under Planning Permission?

For a single storey extension, the maximum size that can be constructed without having to submit an application for Planning Permission includes:

• An extension should have a maximum length of 6m, if you reside in a terraced home or a semi-detached property.

• Extensions for detached properties can have a maximum length of 8m.

• The extension built must not go beyond half your garden’s area.

• The extension should have a maximum height of 4 metres, but in the event whereby the extension is situated within 2 metres of the boundary of your property, it should not exceed a height of 3 metres.

• The extension should not be higher than the highest part of the existing house’s roof.

where to start with a house extension?

Have you decided to improve your property instead of moving? The common problem most homeowners face after deciding to embark on a home extension project is not knowing where to start.

• Do you need a planning permission?

Check with your local authority to determine whether or not you’ll require to submit an application. You can also consult a building expert like an architect for advice.

• What are the building regulation?

Even though planning permission can be dodged, you can not avoid building regulations. These regulations are the set national minimum standards for construction and design which you must comply with to ensure the safety of the individuals in and around it.

• Who will design the extension?

You have to decided whether you’ll hire a professional architect to design the extension or not.

• Who will manage the building work?

If your home extension project is designed and built by a professional company, they’ll be responsible for the management. However, if you decide to use an architect or designed it yourself, you’ll have to hire a main contractor to manage the build.

• How to set the budget?

There are so many factors that can affect the cost of an extension, so it’s better to get the costs from your builder before proceeding.

• Do I need yo inform my home insurance firm?

Absolutely! This is very important as the new extension may affect the rebuilding cost of your property which could have an impact on the policy premium.

• Do I need to inform my neighbours?

It’s very important to discuss your plan with your neighbours before applying for a planning permission and communicate about the concerns they might have.
