Planning a Home Extension in Aberdeen? Here’s What You Need to Know

Thinking about adding extra space to your home? A well-designed home extension can transform your property - whether you're craving a bigger kitchen, need a home office, or want to create an open-plan living space. But before you break ground, there are a few essential things to understand - especially if you're building in Aberdeen or the surrounding areas.

Here’s a practical guide from Sharpsaw Joinery and Builders to help you plan your dream extension confidently and efficiently.

Know What You Want from Your Extension

Before speaking to architects or builders, it helps to be clear on your goals. Ask yourself:

• What will the new space be used for?

• How will it connect to your existing layout?

• What are your non-negotiables?

Popular extension types include:

• Rear extensions – ideal for kitchen-diners or open-plan living

• Side return extensions – perfect for Victorian terraces

• Wraparound extensions – maximise both depth and width

• Two-storey extensions – increase both ground and upper floor space

• Garage conversions – transform underused space into functional rooms

Having a vision early on helps speed up planning and ensures the end result suits your lifestyle.

Planning Permission in Aberdeen: Do You Need It?

In many cases, single-storey rear extensions can be built under permitted development rights. But there are limitations:

• It must not exceed 3m in depth (4m for detached houses)

• It must not cover more than half of your garden

• Height restrictions apply near boundaries

For larger projects or those in conservation areas, planning permission may be required. Sharpsaw can help assess whether your extension qualifies for permitted development or if you’ll need to submit an application to Aberdeen City Council.

Don’t forget: even if planning permission isn't needed, building regulations approval always is. We’ll ensure your project complies with insulation, drainage, structure, electrics, and more.

How Much Does a Home Extension Cost in Aberdeen?

The cost of a house extension in Aberdeen varies depending on size, design, materials, and whether internal works (like kitchens or bathrooms) are included.

As a rough guide:

• Single-storey extension: £1,800 – £2,500 per m²

• Double-storey extension: slightly more per m²

• High-spec finishes or structural changes can increase costs

Timeline: How Long Will It Take?

Every extension is different, but typical timelines include:

• Planning & design: 4–8 weeks

• Permissions & building warrant (if needed): 6–12 weeks

• Construction: 8–16 weeks (depending on size and complexity)

We work efficiently while maintaining high standards, and we always keep you informed through every stage of the build.
