Home extensions come in many shapes and sizes, but one of the most popular entry-level house extensions include single storey extensions (i.e. ground floor extensions). They not only create extra space by extending your home but they can also change the layout of the existing building.
For example, you could extend a room in the house like the kitchen, which is a very popular single storey extension. Extending a house can also create other home additions such as a utility room, storeroom, dining room, bedroom, bathroom, shower room, en suite or even a home office.
Where do i start?
When considering a single storey (ground floor) extension you need to firstly consider the things you would class as essentials. If you are building an extension, what are the features you need, are you trying to achieve a particular goal and what are the options you have?
The next thing is to map out the actual design and build of these property extensions by establishing where everything will be and how it will all fit together. For example if the kitchen is to be part of the new extension, will this have a central bar or will the inside area connect to an external seating area.
It is at this point you should think about appointing a designer who understands what you are trying to achieve and who can then present this visually. Once you have this side of things taken care of it is then time to find a builder who can advise on the practical building methods and most suitable options available such as using bi folding doors rather than sliding doors.
Cost Effective?
Single storey extensions can be more cost effective that a two storey (double) extension in the short term because they require less substantial foundations. However, if you are planning on building another storey above your initial extension, you should think about investing into suitable foundations from the start to avoid having to reinforce them further down the line which will add to the long term costs.
Planning Permission
With some projects you may be able to undertake the work without having to make an application for planning permission. 4C’s would always advise to check with your local authority what the options are available to you as well as the other approvals you require because in some areas there are greater restrictions than others.
If you plan on undertaking a permitted development (PD), we would advise applying to the local authority for a certificate of lawful development. Although you can in fact build without one, it at least gives you the proof to show you met the requirements of a PD in order to not need planning permission.
With a PD project although you are not required to obtain planning permission, there are a number of limitations and criteria that must be met. Examples include the height and the footprint (i.e. area the build covers or impacts) of the build, which are both limited. You also have to use materials which are similar to the existing building so if you are planning on using something different which is perhaps a little more contrasting, you will need to obtain permission and submit a planning application.
