Maximise Your Space with a Conversion:
An Introduction to Transforming Your Property

In simple terms, a conversion involves transforming an existing, underused part of your property into a functional living space. This could be anything from an extra bedroom, home office, or playroom to a fully self-contained annexe. By making better use of the space you already have, you can increase both the practicality and value of your home.

Conversions are often more straightforward and affordable than building an extension, as the basic structure is already in place. That said, each project is unique, and there are important factors to consider, such as design, planning permissions, and building regulations. That’s where we come in.

At E Partridge Building Services, we help you understand what’s possible with your property and guide you through the entire process. Whether you’re in the early stages of exploring ideas or ready to get started, we’re here to help. Our team offers expert advice and support at every step.

When you’re looking to improve your home, there are a few different options available: conversions, extensions, and renovations. While they all enhance your property in their own way, there are some key differences between them.

At EP Builders, we can help you decide which option makes the most sense for your home, needs, and budget. Whether it’s a conversion, extension, or renovation, our team is here to deliver a solution that works for you.

Understanding whether or not you need planning permission is a key part of starting any conversion project. The good news is that, in many cases, home conversions can be carried out without formal planning consent. This is especially true if they fall under what’s known as Permitted Development Rights (PDR). These rights allow homeowners to make certain changes to their property without full planning approval. This applies as long as specific rules and limits are followed.

Many common conversions can be completed without planning permission if they fall under permitted development.

Loft Conversions
Most loft conversions are permitted development, provided they follow planning guidelines. The extension must not exceed the highest part of the roof, and dormers shouldn’t project too far from the slope. Materials should match the existing property, and side-facing windows must be obscure-glazed to protect privacy. Volume limits apply: 40 cubic metres for terraced houses, 50 cubic metres for detached and semi-detached homes. Always check with your local authority before starting.

Garage Conversions
Converting an existing garage into an internal room, like a home office or gym, usually falls within permitted development. This applies as long as you’re not enlarging the building or significantly changing its external appearance. Detached garages being extended or rebuilt will often need permission.

Basement Conversions
Internal changes, such as turning a storage area into a habitable space, typically don’t need planning permission. However, if you’re adding windows, external light wells, or excavating to increase headroom—especially if the exterior is affected—you may need approval.

While many conversions can be done under permitted development, there are situations where planning permission is definitely required. These include:

Listed Buildings and Conservation Areas
If your property is listed, any conversion work (internal or external) will likely require listed building consent and possibly full planning permission. Properties located in conservation areas, Areas of Outstanding Natural Beauty (AONB), or national parks are subject to stricter planning controls. Permitted development rights may be limited or removed altogether.

Significant Changes to the External Appearance
If your conversion changes the way your property looks, you may need permission. This includes adding large dormers, external staircases, balconies, or prominent new windows. Local planning authorities typically assess whether such changes affect the character of the building or the surrounding area.

Exceeding Permitted Development Limits
Permitted development comes with strict size and design limitations. If your proposed conversion exceeds these limits—whether in terms of height, volume, or overall scale—you’ll need to submit a full planning application.

Barn Conversions
Barn conversions often fall outside of permitted development, but they usually require full planning permission. This is particularly true when the building is no longer used for agricultural purposes. It also applies when significant structural changes are planned. However, some agricultural buildings may be converted under a process known as Class Q permitted development, subject to prior approval from your local council.

Commercial-to-Residential Conversions
Turning a commercial building, such as an office or shop, into a residential property often requires planning permission or prior approval. This will of course depend on the nature of the building and its location. While some conversions may fall under permitted development, the criteria are strict. Factors like noise impact, contamination risks, and natural light must be considered.

Not Sure if You Need Planning Permission?
If you’re uncertain whether your conversion project requires planning permission, it’s always best to check with your local planning authority or seek advice from professionals like our team at E Partridge Building Services. We can assess your project, guide you through the relevant regulations, and handle any necessary planning applications on your behalf. Our goal is to make the process as simple and stress-free as possible, so you can focus on bringing your vision to life.
