FAQs

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 much does a two storey house extension cost?

If you’re considering adding a two storey house extension, then setting a budget for this project would be a great way to get started. Similar to a rear extension, a two storey extension usually leaves the rest of the building needing some work and, due to its size, this may imply the re-development of the entire house - which is why they can be very costly. Some of the other influencing factors that can have big impact on a two storey house extension cost includes: your location, the size of the build, complexity of the design ( anything beyond the standard build will normally require more expertise and time), the glazing to be incorporated ( the more the glass used in the project, the more the material cost), as well as the team used.

Generally, when it comes to extensions, the major part of the expenses will be made on the build of the project. This is because it doesn’t only cover the material cost but also the contractor’s overhead as well as the daily rates. At this stage, the extension prices can be determined by the standard of the work that’s being done.

For a fairly average room size of about 18 square metre, the two storey extension should cost within the range of £2,500 to £3,000 per square metre - with the range being determined by the finishes incorporated. Therefore, a two storey extension of about 18 square metre should cost within the range of £45,000 to £55,000. However, this is with the assumption that there are standard window sizes, bathroom suits are modest, and without any need for any purpose joinery or glazing. If you wish to include all these extra features you’ll also have to pay more to make the total cost between £70,000 to £80,000.

are house extensions worth it?

Often referred to by many as the holy grail of home improvements, house extension comes with a wide range of benefits which makes it easy to see why the extension could be a great uptick in the potential price of your property in terms of sales. So if you’re looking to build a new home extension but still not convinced about the project, we’re here to help you. Being fully aware any home construction work is usually a heavy investment, there’s a huge need to be set on your decision before scheduling the commencement of any work. So are house extensions worth it? Below are some of the top benefits offered by house extensions to help you decide if it’s the most suitable route for you.

• Add To Your Home’s Value

Building an home extension is a great way to add value to your home before selling. Increasing the living space of your home is an incredible appeal to many buyers which significantly increases your property’s total value. However, you must ensure that the extension is impressively designed using top quality materials in order to generate more value.

• Good Alternative To House Moving

The most common reason for moving is usually due to a lack of sufficient space, but with house prices steadily on the increase a cost effective alternative is highly sought after. This alternative is house extension which creates more space for the household to spread out and have more privacy.

• You May Not Require A Planning Permission

You can extend your house and still not need to apply for a planning permission. To achieve this, simply comply with the laid down rules set under the permitted development rights.

• Extra Living Space

If you fill you’re starting to outgrow your existing structure and do not buy into the idea of moving, then your best bet might just be to extend your home.

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.
