House Extensions Wirral

We’re a Liverpool-based company, but a huge part of our work is across the water in the Wirral. From Bebington to West Kirby, Heswall to Hoylake, we’ve been building extensions for Wirral families for over 40 years. We know the area, we know the housing stock, and we know what Wirral Borough Council’s planning department expects.

The Wirral has some of the most beautiful residential areas in Merseyside, and the properties reflect that. Whether you’re in a period home in Caldy, a 1930s semi in Bebington, or a modern detached in Heswall, we design and build extensions that respect the character of your home while giving you the space you need.

Types of Extensions We Build in the Wirral

We offer the full range of extension services across the Wirral peninsula:

Single-storey extensions for open-plan kitchen-diners and family rooms
Two-storey extensions for extra bedrooms and living space on both floors
Rear extensions to open up the back of your home onto the garden
Wraparound extensions for a complete ground-floor transformation
Garage conversions for home offices, gyms, and extra bedrooms

Our 4-Step Process

1. Design & Planning

We visit your Wirral home, take detailed measurements, and discuss your vision. Our design team produces full architectural drawings and we handle the planning application with Wirral Borough Council. We know their requirements well and have an excellent approval rate.

2. Foundations & Structural Work

Our groundwork team excavates and pours the foundations, builds the structural walls, and installs all steelwork. Wirral properties can have different ground conditions to Liverpool, particularly near the coast in Hoylake and West Kirby, and we survey the ground thoroughly before we start.

3. Build & Fit-Out

The roof is constructed, windows and doors are fitted, and our plumbers and electricians install all first-fix services. Insulation, plastering, and second-fix work follows. We source materials that match the character of your existing property, whether that’s matching Victorian brickwork in Birkenhead or stone detailing in Caldy.

4. Finishing & Handover

All decorating is completed, kitchens and bathrooms are fitted if included, and the space gets a thorough clean. We walk you through the finished extension, hand over all Building Regulations certificates and warranties, and make sure you’re completely satisfied before we leave.

Planning Permission in the Wirral

Planning rules in the Wirral are the same national rules as Liverpool, but Wirral Borough Council has its own local planning policies. Key things to know:

Conservation areas: Parts of Birkenhead, Port Sunlight, and Caldy are in conservation areas where stricter rules apply to materials and design.
Permitted Development: The same national PD rules apply in the Wirral, so many single-storey extensions don’t need full planning permission.
Coastal properties: Homes near the coast in Hoylake, Meols, and West Kirby may have additional considerations around flood risk and coastal erosion.

We handle all planning applications and know exactly what Wirral Borough Council expects.

Areas We Cover in the Wirral

We work right across the Wirral peninsula, including:

Bebington and Bromborough — Popular for family extensions on the 1930s-1960s housing estates
Heswall — Larger detached properties, often with generous plots ideal for two-storey extensions
West Kirby and Hoylake — Coastal properties with stunning views, where extensions need to complement the seaside setting
Caldy — Premium properties where high-spec, architect-designed extensions are the norm
Birkenhead and Wallasey — Victorian and Edwardian terraces and semis, ideal for rear and wraparound extensions
Neston and Parkgate — Rural-edge properties where we work sympathetically with the local character
Meols and Moreton — A mix of property types, from bungalows to detached family homes

Neighbourhood Spotlight: Heswall

Heswall is one of the Wirral’s most desirable areas, and we’ve completed numerous extensions there. The large detached homes along Telegraph Road and the surrounding streets often have generous plots that allow for substantial two-storey extensions. A typical Heswall project involves adding a large kitchen-diner on the ground floor with a master bedroom suite above, using materials that match the existing property. The result is a home that feels significantly larger while maintaining the premium feel that makes Heswall properties so sought after.

Frequently Asked Questions

1. Do you charge extra for working in the Wirral?

No. We’re based in Liverpool but the Wirral is one of our core working areas. There are no additional travel charges for any location on the Wirral peninsula.

2. How long does an extension take in the Wirral?

The same as Liverpool. A single-storey extension takes 12-16 weeks, a two-storey extension 16-24 weeks, and a garage conversion 4-6 weeks. We provide a detailed schedule before we start.

3. Do I need to use Wirral Borough Council or Liverpool City Council for planning?

If your property is in the Wirral, your planning application goes to Wirral Borough Council. We handle the entire process and know their requirements well.

4. Can you match the brickwork on older Wirral properties?

Yes. Many Wirral properties, particularly in Birkenhead, Bebington, and Heswall, have distinctive brickwork. We source matching bricks from specialist suppliers to ensure the extension blends seamlessly with the original house.

5. What about properties near the coast?

Coastal properties in Hoylake, West Kirby, and Meols may have additional planning considerations around flood risk. We assess this during our initial survey and factor it into the design. We also use materials that withstand the coastal environment.

6. Can you recommend an architect for a larger Wirral project?

For most extensions, our in-house design team handles everything. For larger or more complex projects, we work with several excellent local architects who specialise in residential extensions in the Wirral. We can recommend someone who suits your project and budget.
