Choosing the right architect for your house extension

If you are planning to add an extension to your London or Hertfordshire home, one of the first things to consider is finding the right architects to prepare the architectural and structural drawings.

There are many ways to find a local architect. Below are just some of them:

  • Google Search is one of the first stops when looking for an extension architect. 
  • If you know someone who had an extension built recently and you like the design, ask them who their architect was. 
  • Another good way to find an architect near you is through an online directory such as Yell. 
  • Make sure that the architect is accredited by the Royal Institute of British Architects [RIBA].
  • Most home extension builders will be able to recommend an experienced local architect they have worked with.

Another option is hiring design and build London specialists, who have their own in house architect as well as a team of experienced builders who can complete the build following the architect's plans and specifications.

Choosing the right design is not as easy as it sounds. What might look like an architectural masterpiece to you might be your neighbour's worst nightmare.

Take a walk around your local area to see what size and type of extensions other people have built. This will give you a good idea of whether or not your plans are likely to be permitted.

An experienced architect will work alongside you to create a design that you will love while also ensuring that it meets your local council's planning and building regulation criteria. It helps if your chosen architect is familiar with the local area.

What should a set of home extension drawings include?

  • Separate architectural drawings for each of the required elevations, floor plans and cross-sections.
  • Measurements marking the dimensions of external walls and the positions of window and door openings.
  • Structural drawings showing the positions of supporting steel posts and beams. 
  • Specification document explaining how the design will comply with the building regulations in key areas.
  • Type of bricks or cladding to be used for the exterior in order to match or complement the existing property.
  • An optional 3d visualisation of the house extension plans. This step costs extra, but it will help you get a much better understanding of how your complete extension will look.
