House Extension FAQs

How much does a house extension in Liverpool cost?

The cost of an extension depends on the type and scale of the proposed extension. A small single-storey extension will normally have very different requirements from a large wraparound or double-storey project. We recommend obtaining a quotation based on the individual project rather than relying solely on a generic square-metre figure.

Do I need planning permission for a house extension?

Not necessarily. Some extensions may be possible under permitted development rights, while other projects require planning permission. This depends on the property and proposed work, so the requirements should be checked before construction begins.

How long does a house extension take?

Timescales vary according to the extension design and amount of work involved. Design, planning and other approvals may also need to be completed before building work begins.

What type of extension should I choose?

The right extension depends on the existing layout and the additional accommodation you require. Rear, side, wraparound and double-storey extensions all offer different advantages.

House Extensions Designed Around Your Home

Every property is different, which is why every extension needs to be considered individually.

When providing House Extension Liverpool, we consider how the proposed extension will connect with the existing building. This helps us develop a solution that provides practical additional living space.

An extension can be used to create a larger kitchen and dining area. The aim is to create space that is practical, comfortable and suited to your requirements.

Types of House Extensions in Liverpool

We deliver several types of house extensions in Liverpool, with the most suitable option depending on the property, available space and your requirements.

Single-Storey Rear Extensions

A single-storey rear extension is a popular way of creating additional ground-floor living space.

They are commonly used for larger kitchens and can help create a brighter and more spacious living environment.

Side and Wraparound Extensions

For properties with available space around the side and rear, a side or wraparound extension can significantly increase the ground-floor footprint.

A wraparound extension combines a side-return with a rear extension and can be particularly useful when creating large kitchen and dining spaces.

Double-Storey Extensions

Double-storey extensions can increase both ground-floor and first-floor accommodation.

They can provide space for additional bedrooms, bathrooms and ground-floor living space.

Planning Your House Extension in Liverpool

Good planning is one of the most important stages of a house extension project.

Before construction begins, consideration may need to be given to architectural design, planning permission, structural requirements, drainage, access and Building Regulations.

Some extensions may be possible under permitted development, while others may require a planning application. This depends on factors including the scale and design of the project.

Rather than making assumptions, the requirements should be established for the individual property and proposed extension.

Our House Extension Liverpool service can help manage the project from early planning through to construction.

From Initial Ideas to the Finished Extension

Our experienced team can provide a professional approach to your extension.

The process typically begins by discussing your ideas and requirements. From there, the project can move through design development, any necessary planning stages, structural preparation and construction.

During the building phase, attention is given to structural work, insulation, roofing and external finishes.

The final stages can include finishing works required to complete the extension, depending on the agreed scope of the project.

Having the different stages managed as part of one overall project can help make the process easier to manage for the homeowner.

Creating More Space Without Moving

One of the main reasons homeowners consider House Extension Liverpool is the opportunity to create additional space without having to leave their existing home.

If you want more space but would prefer not to relocate, extending can provide an alternative to moving.

An extension could create a new dining area or a combination of spaces.

A well-planned extension should not simply add floor area. It should make the overall property more practical.

⭐⭐⭐⭐⭐ Couldn’t recommend Ash and Josh highly enough. They helped me out on a job preparing and getting a concrete slab ready for my extension, and the quality of their workmanship was excellent from start to finish. Both lads were reliable, hardworking and clearly take pride in what they do. Everything was done properly, the job was left tidy, and they went out of their way to help me get everything ready and keep the project moving. Really pleased with the finished job and wouldn’t hesitate to use them again. Top-quality workmanship and two genuinely good lads to deal with. Highly recommended! 👍

I am very pleased with the work done on our patio, bearing in mind that it was a last minute request. The work was completed with professionalism, courtesy, friendliness and speed. After finishing the work, everywhere was cleaned as if they hadn't been there at all. I would certainly recommend their services. Thank you Josh, Ashley and the crew.

We have worked along side Josh & Ash from the initial design enquiry to build completion. Josh is very proactive and reactive to all customer questions from the initial enquiry, ensuring the client is updated on every stage of the design even before the build commences. During the build correspondence is a must for clients, and Josh is 100% there for every question and minor details the client asks, reassuring for the client who is having their dream built. The quality and detail of their work is excellent, a "builder" who can actually read drawings and comfortably communicate with other professionals involved behind the scenes. It is a pleasure to work with Off Market Developments, and I have no hesitation in working along side them or recommending them to my customers.

We used Off-Market Developments for a wraparound double-storey extension. As most people know there is always apprehension and anxiety with building work which is why I chose Off-Market due to the recommendations I had in person. Ashley and his team were professional and kept communication clear from start to finish. The most important part of the job the workmanship was immaculate. Every target set was hit on time with great attention to detail in every aspect of the build, the lads were a pleasure to have at my property and I cannot fault them at all, I will happily recommend them to anyone for a job thankyou for such a great experience

We recently had a single-storey house extension completed, and I couldn’t be happier with the entire experience. From the initial consultation through to the final finish, everything was handled with professionalism, attention to detail, and clear communication. The team really took the time to understand what we wanted and offered helpful suggestions to make the most of the space. The build quality is outstanding — the new extension blends seamlessly with the existing house .It’s brighter, more spacious, and far more functional. The project was completed on time and within budget, which made the whole process stress-free. The builders were punctual, tidy, and respectful throughout, always keeping disruption to a minimum. I would highly recommend this service to anyone considering a home extension. It’s added real value to our property and genuinely improved our quality of life. A five-star experience from start to finish!

Ash was very professional and hard working. He came to have a look and assess what was needed. He then gave me a quote and a date and time of when the job could be done. He arranged for all of the stock to be delivered before the job start date. He turned up early in the morning, and didn't stop until the job was completed. 100% happy with the work ethic, price and quality of work. Will definitely use again.
