What Size Extension Can I Build Without Planning Permission?

A common question we receive is how far you can extend a house without needing planning permission.

The answer largely depends on the type of extension you’re planning. Rear extensions are generally the simplest to arrange with local authorities, involving the least red tape. They are among the most straightforward house extensions to execute.

In most cases, single-storey extensions do not require planning permission, provided they adhere to specific guidelines. For detached houses, this means the extension can be up to four metres deep, while for other types of houses, it can be up to three metres deep.

Do I Need an Architect for an Extension in the North West?

If you’re considering a house extension in the North West, you might wonder whether you need to hire an architect.

While it’s possible to manage a house extension or renovation on your own, it’s strongly recommended to seek professional assistance during the design and planning phases. Proper assessment of your home’s structure before beginning any construction work is crucial to avoid potential issues such as compromising the structural integrity of your home.

Although hiring an architect is not mandatory for a house extension in Manchester or elsewhere in the UK, having your plans reviewed by a qualified professional is advisable to ensure a successful project.

How Can I Extend My House Affordably?

There are several ways to add space and value to your home while staying within a budget. If you’re looking for cost-effective house extension ideas, consider the following:

  • Extend Your Kitchen: If your budget only allows for one room, extending the kitchen can be a smart choice. According to the Royal Institution of Chartered Surveyors, kitchen extensions can increase your home’s value by up to 4%. The kitchen is often the heart of the home, making additional space particularly noticeable here.

  • Opt for a Single-Storey Extension: Single-storey extensions in the North West are generally more affordable than double-storey ones, sometimes costing up to 50% less. If you’re on a tight budget, one floor might be the way to go.

  • Consider a Conversion Instead of an Extension: Converting existing spaces such as basements, garages, or lofts can be a more economical way to enhance your home compared to building an extension. You can use our loft conversion cost calculator to get a better idea of potential savings.
