Off Market Developments offers professional House Extension Leigh services, helping homeowners make better use of their existing homes. With years of construction experience, our team combines attention to detail with modern design to deliver kitchen, wraparound and rear extensions throughout Leigh and the wider North West.
The cost of an extension depends on the amount of work involved and the chosen finishes. 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.
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.
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.
The right extension depends on your home, budget and intended use of the new space. Rear, side, wraparound and double-storey extensions all offer different advantages.
Off Market Developments delivers professional House Extension Leigh services, helping homeowners create valuable additional living space. Whether you need a larger kitchen and dining area, a carefully designed house extension can transform the way you use your home.
We provide a wide range of house extensions throughout Leigh, including single-storey rear extensions, side-return extensions, two-storey home extensions, wraparound extensions, and kitchen and dining extensions. Every project is carefully planned around the existing property.
When planning House Extension Leigh, we take the time to discuss your ideas and requirements. This allows us to develop an extension that makes practical use of the available space.
Our comprehensive home extension service can cover the project from initial ideas and architectural design through to construction. Depending on the project, this may include architectural design, support through the planning process, structural design, Building Regulations requirements, construction and interior finishing.
Our construction team works closely with architects, engineers and trusted trades throughout the project. This helps ensure your extension is carefully planned and professionally constructed.
If you’re considering House Extension Leigh, our specialists can discuss your ideas and help you plan the next stage of your project. Talk to our house extension specialists to tell us what you would like to achieve.
Every property is different, which is why every extension needs to be considered individually.
When providing House Extension Leigh, we consider the layout and character of the existing home. 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.
We design and build several types of house extensions in Leigh, with the most suitable option depending on the property, available space and your requirements.
Extending from the rear of a property can provide valuable additional space while creating opportunities to redesign the existing ground floor.
They are commonly used for additional living areas and can help create a modern and flexible living environment.
For properties with suitable space alongside the existing building, a side or wraparound extension can make better use of previously unused space.
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 can increase both ground-floor and first-floor accommodation.
They can provide space for additional bedrooms, bathrooms and ground-floor living space.
Good planning is an important part of any successful extension.
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 type of property and proposed work.
Rather than making assumptions, the requirements should be established for the individual property and proposed extension.
Our House Extension Leigh service can help bring together the design and construction stages.
Our house extension specialists can provide a complete approach to your extension.
The process typically begins by discussing your ideas and requirements. From there, the project can move through architectural planning, any necessary planning stages, structural preparation and construction.
During the building phase, attention is given to the main construction work and integration with the existing building.
The final stages can include plastering and interior finishing, depending on the agreed scope of the project.
Having the different stages managed as part of one overall project can help make the process more organised for the homeowner.
One of the main reasons homeowners consider House Extension Leigh 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 larger family kitchen or a combination of spaces.
A well-planned extension should not simply add floor area. It should create a better connection between existing and new rooms.
Successful extension projects require careful planning, good communication and experienced construction professionals.
At Off Market Developments, we focus on quality workmanship, careful planning and clear communication.
Our team works with trusted professionals throughout the design and construction process to deliver extensions that are designed around the existing property.
If you’re considering House Extension Leigh, our experienced team can help you explore the options available for your property.
Contact us today to discuss your home, the additional space you need and the type of extension you’re considering. We can discuss your requirements and provide a personalised quotation.

⭐⭐⭐⭐⭐ 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! 👍Posted on Google![]()

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.Posted on Google![]()

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.Posted on Google![]()

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 experiencePosted on Google![]()

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!Posted on Google![]()

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.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
