Can extensions suffer from subsidence?

As with any building, home extensions can be affected by subsidence which can crack walls and cause doors to become misaligned.

During the process of planning your extension, your builder and architect should discuss the site with you and put in place appropriate foundations to provide the most stable surface possible to build on.

Your installer will fit windows and doors to the extension securely.

How long does an extension take to build?

The length of time it will take to complete your home extension will depend on a number of factors including the size of the development work, and whether or not you are planning to live in the house when work is carried out.

For a single storey extension, it will normally take around 3 months for the work to be completed.

The first step in the process is for the site to be prepared.  It usually takes around 2 weeks to dig out the footings and prepare the foundations, and then a further 2 weeks to install the damp course and any drains that are needed around the extension.

By week 5 of the process, your builders will normally be working on the external walls and putting in place blockwork to provide cavity wall insulation.  Ties would be used to integrate the new brickwork into your existing walls.

The next two weeks will usually be devoted to fitting the roof structure and internal walls.  

At this point, the structure will need to be made weather proof which is when your Independent Network Installer should be on site fitting your new uPVC windows and doors.

From this point on, electricians or gas fitters will need to be on site to add power to the extension.  This fit will be followed by the plastering of internal walls and breaking through into your existing house.

Once the plaster is dry and decorating has been completed - and any units or furniture fitted, your extension will be ready to use.

A two storey extension will normally take a few weeks longer depending on the complexity and size of the project.

Do I need planning permission for an extension?

In some cases, an extension to your house is considered to be permitted development, which means that it does not require planning permission.  Larger home extensions, or those in designated areas will often need specific planning permission or be subject to a neighbour consultation schemes.

Planning permission being given will be subject to meeting specific criteria for the building work including how and where windows are placed, and the location of the extension relative to the boundaries of your property.

During the process of planning your extension, your architect will be able to work with you to determine whether you need any specific permission – for example if you are overlooked.

Is there a cost difference if I choose a colour on one or both sides of my product?

Yes, if you choose any other colour rather then 'standard white' as a colour internally or externally there is an extra cost. Visit our visualiser to get an estimate for your home improvement or speak to your local installer for further detail.
