Types Of House Extensions

While planning your dream extension, it’s important to remember that there are various types to choose from, each with their own benefits and designed to accommodate your requirements. At Trendsetter Group, we offer a whole spectrum of extension services, and our most popular home extensions include: 

Single Extension

A single extension, especially a single storey rear extension, is a popular choice for homeowners looking to add extra space to their property without a significant overhaul. This type of extension typically extends one part of your house, such as the kitchen or living room, providing additional square footage on a single floor. It's an ideal option for creating larger, open-plan living areas or for adding a new room like a home office or playroom.

Double Extension

Double extensions offer a substantial increase in space by expanding your home on two levels. This is an excellent choice for families needing extra bedrooms, bathrooms, or larger living spaces. With a double extension, you can significantly enhance the functionality and value of your home, allowing for a complete redesign of your living environment to suit your growing needs.

Wrap Extension

A wrap extension - or wraparound extension - involves extending your property on multiple sides, effectively 'wrapping' around the existing structure. This type of extension is perfect for maximising the potential of your property’s footprint, offering a dramatic increase in space. It is particularly suitable for corner properties or those with ample side and rear space, allowing for a seamless and expansive extension of your living area.

Side Extension

Side extensions take advantage of the unused space at the side of your home. Ideal for semi-detached or detached properties, this extension type can provide the extra room you need without compromising your garden space. Whether it’s for a new utility room, extended kitchen, or even a new dining area, a side extension can be a smart way to enhance your home’s layout and functionality.

Each of these extension types can be tailored to your specific needs, ensuring that your home not only gains additional space but also increases in aesthetic and practical value.

What Our Customers Say

Our Process

On-Site Assessment:

Our process begins with a comprehensive on-site assessment. Our team of experienced professionals will visit your property to understand your vision and assess the feasibility of the extension. During this visit, we take measurements, discuss your requirements in detail, and offer initial design ideas. This step is crucial in tailoring our service to your specific needs and ensuring that the proposed extension is both practical and aesthetically pleasing.

Obtaining Planning Permission:

Navigating the complexities of planning permission is a critical part of our process. We provide expert guidance on all aspects of the planning application, including the preparation and submission of necessary documents. Our team stays updated on local planning regulations to ensure compliance and maximise the chances of your application’s approval. We liaise with local authorities on your behalf, making the process hassle-free for you.

Project Management:

Once planning permission is granted, a dedicated project manager will step in to assist. They oversee every aspect of the construction process, from coordinating with architects and builders to ensuring that the project stays on schedule and within budget. Our project managers maintain open lines of communication throughout, keeping you informed and involved at every stage.

Party Wall Agreement:

If your extension involves work on a wall you share with neighbours, a Party Wall Agreement is necessary. We handle all aspects of this process, from notifying your neighbours to preparing and arranging the agreement. Our team ensures that all legal requirements are met to prevent disputes and delays.

Building Control:

Ensuring that your extension meets all building regulations is a key part of our process. Our team works closely with Building Control to guarantee that all aspects of the build meet safety, design, and environmental standards. We arrange for regular inspections during the construction phase to ensure compliance and provide peace of mind that your extension is built to the highest standards.

This comprehensive approach ensures that your home extension is not only beautifully designed and expertly executed but also legally compliant and structurally sound.

Frequently Asked Questions

The key steps in planning a house extension include initial consultation and on-site assessment, designing the extension, obtaining necessary planning permissions, preparing detailed construction plans, and finally, the construction phase itself. This process involves working with architects, builders, and possibly other specialists to ensure that the extension meets your needs and complies with local regulations.

The duration of a house extension project varies depending on the size and complexity of the extension. A simple single-story extension might take around 3-4 months, while more complex or double-story extensions could take 6 months or more. This timeline includes planning, design, obtaining permissions, and the actual construction work.

Yes, most house extensions require planning permission from your local authority, especially if you are altering the structure or footprint of your house. Additionally, the project must comply with building regulations to ensure it is safe and energy-efficient. Our team can assist you in navigating these requirements and obtaining all necessary permits.

The cost of a house extension varies widely based on factors like the size of the extension, the quality of materials used, and the complexity of the design. On average, a basic house extension might start from a few thousand pounds, but more elaborate projects can cost significantly more. We provide detailed cost estimates after the initial assessment to give you a clear understanding of the financial commitment involved.

In many cases, you can continue living in your home while the extension work is carried out. However, this depends on the nature and scale of the project. For larger or more complex extensions, it might be more practical to relocate temporarily due to factors like noise, dust, and potential disruptions to utilities. We ensure clear communication about the impact of construction and strive to minimise inconvenience.
