FAQs

Should I use concrete or timber footings?

For 2 metre solid fences it’s recommended to use concrete posts to support each panel. For smaller 1 metre fences or for picket fences with gaps between each timber piece you can use timber posts. A fencing contractor will be able to advise you on the best materials from the length and requirements of a new fence.

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.

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.

Can I extend the front of my house?

When it comes to extending a home, the rear of the house often comes to mind a lot more than the front. However, this doesn’t mean that you can’t extend the front of your house. This can be done either as part of a renovation project whereby the entire house is incorporated or it can also be done in isolation. It’s possible to extend the front of your house without the need to apply for a planning permission, however, there are a bunch of limitations you’d have to comply with if you wish to carry out with such a project. Sometimes, this may imply that extending to the front of your home is more tedious and tasking than extending your home’s rear. So exactly how far can you extend the front of your home without planning permission?

 

The short and simple answer to this question is 2 metres square area with a height not more than 3 metres. Generally, you do not need a planning permission to build a front porch as long as its area doesn’t go beyond 2 square metres from a public road or walkway. Also, a tiled or slated roof can be as much as 4 metres but other roofs must not go beyond 3 metres in height. If you want to extend the front of your home beyond the restrictions specified, then you’ll have to apply for a planning permission.

 

Extending the front of home can be quite costly, but this can be controlled by not building to the extension to the highest specification, not including an extension on kitchens or bathrooms and more.
