House extensions can be a difficult subject to discuss when it comes to accurate costs regarding structural design part. There are many variables that may influence price approximation and support configuration such as overall size of the added part, location and size of openings, used materials, volume of glazing, ground conditions, local vegetation including water demanding trees and presence of existing utility services.
This is why it can be very helpful to get the help of experts before you draw up any plans or put them into motion.
It can also help you to have a basic understanding of the different types of house extensions there are and how their complexity can affect the overall cost of your project.
However, to give you a rough estimate, the cost of an average-sized single-storey extension can be anywhere between £1450 and £1850 per meter square, but in London, this could be anywhere between £1800 and £2500+ per meter square.
Things to consider about a home extension project
The cost of building your house extension will vary according to what you want and how complex the added structure will be. Smaller, single-storey extensions are going to be cheaper and quicker to build than a two-storey extension that needs far more technical input.
Also, a factor which you need to consider is where you live. Your local authority may have different rules about home extensions than another authority in the next county. If you live in or near a major city, such as London for example, your extension may cost more than a similar one for someone living in a more rural area.
However, this does not mean that there are not a set of general rules and guidelines that need to be adhered to regardless of where you live. There are statutory Building Regulations and structural elements need to be designed to relevant design codes.
If you have never had an extension built before and are unfamiliar with the process, then you should consider keeping in touch with one of our team members at GL Design Services.
