House Extensions in Reigate

If you're considering a house extension in Reigate, choosing the right builder and planning your project properly can make all the difference.

At Whitley Builders, we specialise in high-quality home extensions across Reigate and the surrounding Surrey area, helping homeowners create more space, improve layout, and add long-term value to their property.

Whether you're planning a kitchen extension, rear extension, or a full remodel, we guide you through the entire process — from initial ideas to completion.

 We carry out a wide range of extensions tailored to different property types in the area.

Ideal for creating open-plan kitchen and living spaces, particularly in semi-detached and terraced homes.

A great option for adding both ground floor space and additional bedrooms or bathrooms.

Very popular in Reigate, allowing homeowners to open up the back of the house and connect living spaces with the garden.

Transforming outdated kitchens into modern, functional spaces designed around how you live.

 Reigate has a mix of Victorian, Edwardian, and 20th-century properties, many of which require careful consideration when extending.

We regularly work on:

• Period homes requiring structural alterations 
• Semi-detached family homes needing more space 
• Detached properties with scope for larger extensions 

We understand the importance of maintaining the character of older properties while creating modern, practical living spaces.

 Many extensions fall under permitted development, but this depends on factors such as:

• Property type 
• Extension size 
• Previous alterations 
• Whether the home is in a conservation area 

We help guide clients through:

• Planning permission (if required) 
• Building regulations 
• Structural design and approvals 

We regularly work with Reigate & Banstead Borough Council, so we understand local planning considerations.

 We aim to make the process as smooth and straightforward as possible.

We discuss your ideas, budget, and what you're trying to achieve.

Working with designers and architects where required to develop your plans.

Finalising specifications, timelines, and key decisions before work begins.

Managing the entire build process, including structural work, first fix, and second fix.

Final finishes, snagging, and handover.

 We’ve completed a number of extension and renovation projects across Reigate and the surrounding areas.

Typical projects include:

• Rear kitchen extensions creating open-plan living spaces 
• Structural knock-throughs to improve layout 
• Full refurbishments alongside extension works

 Costs vary depending on size, specification, and complexity.

As a general guide:

• Single-storey extensions: £2,000–£3,000 per m² 
• Double-storey extensions: often lower per m² but higher overall cost 
• High-spec finishes and structural complexity can increase costs

Not always. Many extensions fall under permitted development, but it depends on your property and the scale of the project.

Most extensions take between 3–6 months, depending on size and complexity.

In many cases, yes — although it depends on the extent of the work.

Ideally before construction starts, to avoid delays caused by lead times.
