Types of Home Extensions We Build
Single-Storey Extensions
Single-storey extensions are a popular choice for homeowners seeking to add ground-floor space without altering the upper levels of their property. Ideal for creating extra living areas, dining rooms, or home offices, these extensions typically involve building outwards from the rear or side of your home. They offer a cost-effective way to increase square footage, often incorporating large windows or bi-fold doors for natural light and garden access, and can be completed relatively quickly with minimal structural changes.
Multi-Storey Extensions
For those needing more substantial space, multi-storey extensions provide vertical expansion, adding rooms on both ground and upper floors, such as additional bedrooms, bathrooms, or en-suites above a new living area. This type maximises your property’s footprint and is particularly suited to growing families or owners who would rather develop for more space rather than relocating. Our designs ensure seamless integration with your existing home’s architecture, enhancing overall flow and functionality while boosting property value.
Wrap-Around Extensions
Wrap-around extensions cleverly utilise the side and rear of your home to create a larger, L-shaped addition that wraps around the building. This versatile option is excellent for open-plan living, combining kitchen, dining, and lounge areas into one cohesive space. It allows for creative layouts, such as incorporating corner bi-folds for panoramic views, and is a smart way to make the most of awkward or underused outdoor areas without compromising on aesthetics.
Open-Plan Extensions
Open-plan extensions focus on removing internal walls and barriers to create fluid, spacious living environments that blend kitchen, dining, and sitting areas. Perfect for modern lifestyles, these designs promote family interaction and entertaining, often featuring structural elements like steel beams for support and large glazing for brightness. We tailor them to your needs, ensuring practical zoning while maintaining a contemporary, airy feel that transforms dated layouts into vibrant hubs.
Kitchen Extensions
Kitchen extensions are tailored to revolutionise your cooking and socialising space, whether by enlarging an existing kitchen or adding a new one as part of a larger build. Options include breakfast bars, islands, or utility areas, with emphasis on functionality, storage, and high-end finishes. These extensions often incorporate energy-efficient appliances and underfloor heating, making them your favourite place in your house, while improving daily life and resale appeal.

Service for Extensions
At Action Roofing & Building Services, our full design and build service takes the hassle out of your home extension project, guiding you from initial ideas through to completion with expert support every step of the way. We begin with detailed consultations to capture your requirements, then produce professional architectural drawings and 3D visualisations to bring your vision to life. A key advantage is our assistance in obtaining planning permission, we handle the entire application process, including submitting plans, liaising with local authorities, and addressing any revisions to ensure swift approval.
Having worked closely with Sefton, Liverpool, and Wirral councils for many years, we have in-depth knowledge of their specific requirements and preferences, which helps streamline approvals and avoid common pitfalls. This integrated approach not only saves you time and stress but also ensures your extension is compliant, sustainable, and optimised for your budget.
Project-Managed Construction
for Extensions
Our project-managed construction process ensures your home extension is delivered smoothly, efficiently, and to the highest standards. Every build is overseen by an experienced project manager who coordinates all tradespeople, suppliers, and timelines, keeping everything on schedule and within your agreed budget.
Your dedicated project manager will conduct regular quality checks at key stages, such as foundations, structural work, and finishing touches, to maintain superior workmanship and compliance with regulations. Clear communication is central to our approach; your project manager provides frequent updates, addresses any queries promptly, and involves you in decisions to ensure the final result aligns perfectly with your expectations. This hands-on management minimises delays, reduces risks, and gives you peace of mind throughout the construction phase.
Home Extensions FAQ
What types of home extensions do you specialise in?
We build a range of extensions including single-storey for ground-floor additions, multi-storey for vertical expansion, wrap-around for L-shaped layouts, open-plan for fluid living spaces, and kitchen extensions for enhanced cooking areas. Each is customised to your property and needs in Crosby, Liverpool, and Merseyside.
How long does it take to build a home extension?
Timelines vary by size and complexity: a single-storey extension might take 8–12 weeks, while multi-storey or wrap-around could span 12–20 weeks. This includes design, planning, and construction phases, we provide a detailed schedule upfront.
Do I need planning permission for a home extension?
Many extensions qualify under permitted development rights and don’t require planning permission, but larger projects, those in conservation areas, or those exceeding specific limits often do. We handle the full application process and use our experience with Sefton, Liverpool, and Wirral councils to guide you effectively.
What size extensions can be built without planning permission?
Under permitted development rules in England (subject to your property type and location), single-storey rear extensions on detached houses can often extend up to 8 metres deep, or 6 metres on semi-detached/terraced houses (with neighbour consultation for larger sizes). Side extensions are typically limited to half the width of the original house and single-storey only. All extensions must not cover more than half the land around the original house. We assess your specific property to confirm eligibility and advise on any restrictions.
When do I definitely need planning permission for an extension?
You usually need planning permission if: the extension is more than one storey at the side or rear (beyond certain limits), it exceeds permitted development depth/height rules, your property is in a conservation area, listed building, or if permitted development rights have been removed. Multi-storey or wrap-around designs often require it. Our team checks this during your free consultation.
How much does a home extension cost?
Costs depend on type, size, finishes, and site specifics, but expect £1,500–£3,000 per square metre for a standard build, with premium features or multi-storey work at the higher end. We provide a transparent, fixed-price quote after a free site survey, breaking down all elements from design to completion.
What happens if there are unexpected issues during construction, like ground conditions?
We carry out thorough site investigations where needed and build contingency into our planning. If unforeseen issues arise, your project manager communicates them immediately, provides options, and agrees any adjustments to keep the project on track.
Can I make changes to my extension plans once they've been submitted or during construction?
Yes, changes are possible, but the impact depends on the stage. Minor amendments such as window positions or internal layouts can often be handled via a non-material amendment or during the build. Significant changes like increasing size or altering height may require a new or revised planning application. We discuss any proposed changes promptly, explain implications for cost, timeline, and approvals, and manage the process to keep your project moving smoothly.
