Do you need planning permission for a pool house build?

At Westbury, we know that building a pool house may feel like a daunting project. Whether you are planning to cover an existing pool or create a relaxing space with a new pool, there are many things to consider when it comes to your pool house build.

The biggest consideration? Planning permission. The good news is that not all pool houses need planning permission, and if they do, we are here to help you every step of the way.

When a pool house doesn’t require planning permission

In most cases, pool houses are classed as outbuildings and therefore do not need planning permission, provided they meet certain criteria. The Planning Portal outlines these conditions in detail.

However, it is always best to check with your local authorities first before taking the next step, even if your property or building seems to comply.

Things to consider when applying for planning permission

In order for your build to be considered for development, there are certain criteria you need to meet, including that it must be a single-storey, not occupy more than 50% of the garden, and not be used as a residence.

However, even if your design meets these conditions, planning permission is still required if:

  • Your property is listed
  • You live in a conservation area, National Park, Area of Outstanding Natural Beauty or a World Heritage Site

In some areas, even the choice of materials may need approval to ensure they match the character of the surrounding landscape of heritage architecture.

You should also consider the impact it may have on neighbours in terms of overshadowing and privacy, the environmental impact it may have, and how the logistics of the building will work, such as the adequacy of parking for staff or contractors.

Designing your new pool house

A well-designed timber pool house is more than just a cover for your pool; it is a relaxing outdoor retreat and can be perfect for any season.

Your pool house could include:

  • A climate-controlled indoor pool area for year-round use.
  • Large bi-fold or retractable doors, making it perfect for entertaining
  • Changing rooms, showers and pump rooms

Because pool houses experience different humidity and temperatures, it is essential to plan for ventilation, heating and air handling to keep the building at a comfortable temperature and free from condensation. Our design team can give you all the guidance on this, so you don’t have to worry about the technical stuff!
