Home Extension FAQ's

There are many factors which will affect how much a house extension costs, including the size and style of the extension, the amount of glazing - both in the walls and the roof - and the type of roof used.

There are many factors which will affect how much a house extension costs, including the size and style of the extension, the amount of glazing - both in the walls and the roof - and the type of roof used.

A tiled conservatory roof is an excellent option if you are either looking to replace an old conservatory roof or build a new room that is more like an extension. Tiled conservatory roofs are very good because they create room that looks beautiful, is very warm, and that looks like an extension but can be built in a fraction of the time.

As a guide, single-storey rear extensions must not extend beyond the rear wall of the original house by more than eight metres if your home is detached, or more than six metres for any other style of house. Extensions of more than one storey must not extend beyond the rear wall of the original house by more than three metres. How far you can extend your house without Planning Permission comes down to the various rules within Permitted Development. These rules look at various factors such as how close you are to your neighbour's home and the type of home you live in. Your local installer or Building Control officer will be able to advise on how far you can extend your home after visiting your home and looking at these factors, as well as the others which make up the Permitted Development rules. 

One of the cheapest ways to extend your home is to add a conservatory with a solid or tiled roof such as Livinroof or Ultraroof from Ultraframe. From the inside they feature a plastered vaulted ceiling just like a traditionally built extension.

One of the fastest ways to extend your home is to add a conservatory with a solid or tiled roof such as Livinroof or Ultraroof from Ultraframe. While they can be fitted as quickly as a conservatory roof, from the inside they feature a plastered vaulted ceiling just like a traditionally built extension.

You don't always need planning permission to add an extension to your home - often they fall under permitted development rules, providing they meet certain criteria about size and other factors. To see the full list of criteria for permitted development visit the Planning Portal.

There are several options for extension roofs, including a solid or tiled conservatory roofing system, a flat roof with lanterns or flat skylights or even a large conservatory roof with an internal pelmet.

Flat roof extensions did used to have a poor reputation due to reports of them leaking but with modern flat roof extension technology, leaks should be a thing of the past.

Whether a lantern or flat skylight is best is partly down to personal preference as some people prefer the height of a pitched lantern roof, while others prefer the simplicity of a flat skylight. Other factors to take into account are the style of your existing home, whether a lantern would obstruct any upstairs windows and whether you are trying to achieve a more modern or traditional look.

The best roof window for a house extension is partly down to personal preference as some people prefer the height of a pitched lantern roof, while others prefer the simplicity of a flat skylight. Other factors to take into account are the style of your existing home, whether a lantern would obstruct any upstairs windows and whether you are trying to achieve a more modern or traditional look.

The biggest factor in determining how long a house extension will take to build is the base work. The time to create a house extension base can vary dependent on the ground conditions and whether piled foundations are needed. Once the base is completed, a house extension could take anything from several weeks if pre-fabricated products are used, to several months if traditional construction methods are used.

How much an extension will add to the value of your house is dependent on a wide number of factors including the area you live in, the impact the extension will have on the property, the style and size of extension and of course, the quality of the installation and products used. What you can be certain of, is that an extension definitely will add some value to your home. A local estate agent or architect may be able to advise on a guide house price increase based on other properties with home extensions in your local area.

The first step to adding an open plan extension to your home is to speak to an architect about design options that will suit your home and meet your aims. They may also be able to advise about whether you will need planning permission for your home extension or if it would be exempt under permitted development rules.

Choosing the right installer is vital in minimising mess during the build of a house extension. Of course, some mess is unavoidable but a good builder/installer should have working practices that keep the mess in and around your home to a minimum.
