House Extensions
House extensions are a brilliant and an effective way of adding more living space to your home or fully utilizing the available space of your property so that you get the best out of it. Usually, you may think of a house extension if you are reluctant to move from your home due to the roots you have built in your living area – friends, family, transport links to your place of work, schools for the kids or even places of worship.
 
Generally when we think of house extensions, there is usually the confusion of the legal requirements (planning permission) and the anxiety of getting the permission to build an extension and this has put off a lot of people from extending their home. The good news is that the permitted development rules have been relaxed which means you can build an extension without planning permission of up to 6 metres or 8 metres if it is a detached house.
 
The cost for a house extension can range from £15,000 to £25,000 for small extensions, £30,000 to £45,000 for midsize extensions and £50,000 to £90,000 for large extensions. Whatever your budget our expert team at CBO Contractors would work on options to suit your budget and also add value to your home.
 
At CBO Contractors, we always recommend that for your house extension to make economic sense, you need to make sure the value added is greater than the cost of the project. As a useful guide, check the value of similar sized properties sold locally to assess if you have got more benefit or otherwise. Here is a description of some of the house extension options below.

Single Storey Side Extension
This is a perfect way to create extra living space in your home. A single storey side extension is where you extend beyond the side elevation of the original house. The type of extension has the following features:
  • It cannot exceed 4 metres in height
  • It can only be up-to half the width of the original house
  • It can only be single storey
This is a common extension for end terrace, semi detached or detached houses if there is available space by the side of the house. Don’t worry speak to our experts at CBO Contractors and they will advice you on the best solution. The estimated minimum cost for a single storey side extension is £18,000. Our team would discuss your available budget and work at a solution for you.

Single Storey Rear Extension
A rear extension is another brilliant way of adding more living space to your home. This could mean adding a lounge area, expanding the kitchen and dining area or adding a play area for the kids. This may be a cheaper solution than moving when the cost of moving including stamp duty costs is taken into account.
This type of extension has the following features:
  • You cannot extend beyond the rear wall of the original house by more than 4 metres if for a detached house or 3 metres for any other house
  • You cannot exceed 4 metres in height
  • There are exclusions were the limit for single storey rear extensions is increased by 8 metres if a detached house or 6 metres for any other house but would require approval by the relevant local planning authority.
This type of extension can apply to all property types – terraced, semi-detached, detached as long as there is enough room at the rear of the building. Usually it takes up part of the garden. Again our friendly team are happy to discuss your options at no extra cost. The estimated minimum cost for a single storey rear extension is £20,000. Our team would discuss your available budget and work at a solution for you.

Side Return Extension
Side Return Extensions is described as an infill of the passage to the rear and side of the property e.g. between two houses. Rear extensions usually result in the loss of garden space while side return extensions makes use of the disused part of the property.

Planning permission isn’t required as side return extensions are considered to be permitted development. However if the extension is within 2 metres of a boundary, maximum eaves height should be no higher than 3 metres to fall into the permitted development category.

With a side return extension you can widen rooms, repurpose areas within the property especially the kitchen and dining areas and make the best of your living space. Our team have developed several projects and so will bring their expertise and experience to your project during the consultation period. The estimated minimum cost for a single storey rear extension is £20,000. Our team would discuss your available budget and work at a solution for you.

Conservatory House Extension
This is a property extension with glass walls and roof which is available in different styles and glazing options usually supported by dwarf walls. The main difference between a conservatory extension and a standard extension is the materials used. Conservatories will feature double glazing while standard extensions use solid brick work or concrete. A conservatory brings more light into the home which means you may use less electricity in your home. However, conservatories usually require building regulations in place before work can commence which may generally slow down the process.
 
Conservatory extensions are typically cheaper than standard extensions due to the materials used. The estimated cost is from £9,000.

Double Storey Extension
Double Storey Extension is a 2 storey extension built to extend the size of a house and its living space on two floors – a ground and second level floor. While it may be possible to build within permitted development (i.e. not requiring planning permission), it is usually likely that planning permission may be required. For instance, if a proposed extension affects a party wall, then notice has to be given to the neighbours before work starts. Double Storey Extensions must be no closer than 7 metres to the rear boundary. If closer than 7 metres to the rear boundary, then you would need planning permission for the extension. Also the materials used for the extension should be similar in appearance to the existing house.

As the number of bedrooms in a house have a direct impact on the value of the property, adding a double storey extension with an extra bedroom would shift the property into the next price bracket. This is much higher than the 5% - 10% value added to the house value from a single storey extension.

The estimated cost for a double storey extension is from £60,000 and our team are on hand to discuss your needs and present the best options for your home and your budget.
