Whether you’re dreaming of a larger kitchen for family gatherings, an extra bedroom for growing needs, our team turns your vision into reality. With years of experience serving homeowners across Liverpool and the surrounding areas, we deliver high-quality extensions that stand the test of time.

Single-Storey Extensions

Ideal for ground-floor expansions like open-plan kitchens, dining areas, or home offices. These extensions provide a cost-effective way to increase living space without altering your home’s upper levels.

Two-Storey Extensions

Perfect for families needing more bedrooms or bathrooms. We maximise vertical space to add significant square footage, often including en-suites or playrooms while maintaining the structural integrity of your building.

Rear Extensions

A favourite in Liverpool’s terraced and semi-detached homes, these extend outward from the back of your property, creating spacious living rooms, utility areas, or even garden rooms that connect indoor and outdoor spaces.

Side Extensions

Great for properties with unused side alleys or gardens. These can transform narrow spaces into functional additions like garages, studies, or extended hallways.

Kitchen Extensions

Designed for modern living, our kitchen extensions incorporate the latest trends in design, from bi-fold doors for natural light to integrated appliances, transforming your kitchen into your dream space.

Wrap-Around Extensions

Wrap-around extensions are ideal for those with space to the rear and side of their property. This extension type can seamlessly add space to your property creating room for open plan kitchens as well as downstairs toilets or bedrooms.

Home Extensions FAQ by Platinum Builders

How much does a home extension cost in the UK?

The cost of a home extension varies based on size, type, and specifications. In Liverpool, a single-storey extension typically ranges from £1,500 to £2,500 per square metre, while two-storey extensions may cost £1,800 to £3,000 per square metre. Factors like materials, glazing, and site conditions also affect pricing. At Platinum Builders, we provide transparent, detailed quotes tailored to your budget during our free consultation.

How long does it take to build a home extension?

The timeline depends on the extension’s complexity. A single-storey extension typically takes 8–12 weeks, while two-storey or wrap-around extensions may take 12–16 weeks. This includes design, planning (if needed), and construction. Our project-managed service at Platinum Builders ensures efficient timelines with minimal disruption, keeping you updated at every stage.

What types of home extensions are there?

Common types include single-storey, two-storey, rear, side, kitchen, and wrap-around extension. Each suits different needs, rear extensions are popular for terraced homes in Liverpool, while side extensions maximise narrow plots. Platinum Builders designs bespoke extensions to match your home’s style and your lifestyle, using premium materials for durability.

How do I choose a reliable builder for my extension?

Look for experience, local knowledge, and strong reviews. Platinum Builders, based in Liverpool, has over 20 years of experience. Check for accreditations (like FMB or TrustMark), detailed quotes, and a portfolio of completed projects. We offer free consultations and references from satisfied clients in areas like Allerton and Crosby.

Will a home extension add value to my property?

Yes, extensions typically increase property value. In Liverpool, a well-designed extension can boost your home’s value by 10–20%, depending on the type and quality. Kitchen and two-storey extensions often yield the highest returns. Platinum Builders focuses on designs that enhance both functionality and market appeal, ensuring a strong investment.

Why should I choose Platinum Builders for my Liverpool extension?

Liverpool homeowners choose us for our local expertise, quality craftsmanship, and comprehensive service. We understand the city’s architectural diversity, from period homes to modern builds. Our end-to-end service includes planning permission support, architectural design, and project management, all with transparent pricing and a focus on customer satisfaction.

Can I live in my home during an extension?

Yes, in most cases, you can stay in your home during construction. We prioritize minimizing disruption by scheduling noisy work strategically and maintaining clear communication. For larger projects, like two-storey extensions, some areas of your home may be temporarily inaccessible. Platinum Builders ensures a tidy site and safe access throughout the process.

Do I need architectural drawings for an extension?

Yes, architectural drawings are essential for extensions, especially those requiring planning permission or complex structural work. They ensure compliance with building regulations and guide construction. Platinum Builders works with qualified architects to provide detailed, tailored drawings, including 3D visualisations, to bring your vision to life.

What are the building regulations for home extensions?

All extensions must comply with UK building regulations, covering structural safety, insulation, fire safety, and drainage. In Liverpool, additional rules may apply in conservation areas. Platinum Builders handles all regulatory requirements, coordinating inspections and ensuring your extension meets standards for energy efficiency and safety.

Do I need planning permission for a home extension?

Not all extensions require planning permission. Many fall under Permitted Development (PD) rights, especially single-storey rear extensions up to 4 metres (detached) or 3 metres (semi-detached/terraced) in depth. However, larger projects, two-storey extensions, or those in conservation areas (common in parts of Liverpool like Sefton Park) often need approval. Platinum Builders assists with planning applications, ensuring compliance with Liverpool City Council regulations.
