FAQs about designing home extensions answered by our structural engineer

If you are looking to add value to your property in 2023, one of the easiest ways to do this is with a stylish and professional addition being made.

For most people, this will take the form of an extension that is usually added to the back of the property. While classy and very high-end, few people have ever had to consider having an extension built before and may not know where to begin with the planning. And that is where our team comes in.

At GL Design Services, we can help with all manner of home modifications, from extensions to loft conversions, and we will always be happy to assess your property for suitability for these works to be performed, all while offering a quote from our structural engineer Croydon that may be lower than you think. Great!

But with that in mind, you may have some questions about having a home extension, and here, our structural engineer Croydon answers common queries that we receive.

How much value will an extension add?

The value that a home extension can add to a property can vary significantly depending on a number of factors, which can include the location of the property, the size and scope of the extension, and the current real estate market. In general, a well-designed and executed home extension can add significant value to a property by increasing the size and functionality of the living space.

Our structural engineer Croydon will usually only be able to give you an estimate of how much value an extension will add as market trends in house prices will shift but rest assured, we will always aim to plan an extension that will boost the value significantly. If you have a set price in mind that you want to add to the value of your home, we can design an extension with this in mind too.

Will I need to adhere to building regulations with my home extension?

Yes, you will. If you are planning a home extension in the UK, you will need to apply for building regulations approval before beginning construction. This involves submitting a building notice or full plans application to the local building control body, which will review the plans to ensure that they meet the relevant building regulations. You will also need to hire a building control surveyor to carry out inspections of the work as it progresses to ensure that it complies with the approved plans and the building regulations.

How big should the extension be?

There are guidelines in the Uk about the maximum size of a home extension.

For most types of properties, the maximum size of a home extension that can be built under permitted development rights is:

  • Single-story extensions: Up to 4 meters in depth for detached properties and up to 3 meters in depth for all other types of properties.
  • Two-story extensions: Up to 3 meters in depth for detached properties and up to 4 meters in depth for all other types of properties.

But, provided that your home extension is within these parameters, the size of the extension is entirely up to you. If you aren’t sure which size extension would be the most suited to your property, we can help with this aspect of the design too.
