No1 Extensions and Conversions Ltd: Manchester’s Premier Extension Specialists

Committing to a house extension without really being able to picture the finished result is one of the biggest sources of anxiety in home improvement. No1 Extensions and Conversions Ltd, led by Matt and based in Prestwich, has tackled that problem head-on by offering customers a VR design experience — letting homeowners genuinely walk through their extension before a single brick is laid. Backed by a stated 1,000-plus completed projects and a fixed price guarantee, the business has built a strong reputation across Manchester, Bury, Bolton, and the wider North West.

Whether it’s a bespoke house extension, a full loft conversion, or turning an unused garage into a functional utility room, No1 Extensions and Conversions offers homeowners a design-led, professionally managed building service from first consultation through to completion.

About No1 Extensions and Conversions — Meet Matt and the Team

No1 Extensions and Conversions Ltd are specialist builders based in Radcliffe, Manchester, covering Manchester, Bury, Bolton, and the surrounding areas, helping homeowners transform their space with high-quality house extensions, garage conversions, and loft conversions, all designed, managed, and built to a high standard. The team handles every stage of a project, from the first site visit and design support through to structural work, electrics, plumbing, and finishing.

Led by Matt, the business has built its reputation on providing 100% customer satisfaction, with reviews consistently praising clean, reliable workmanship and clear communication throughout every project. The company positions itself around honest advice and transparent pricing, aiming to add genuine value to a home rather than simply completing a build to the minimum standard.

See Before You Build — VR Design Experience

One of the more distinctive parts of No1 Extensions and Conversions’ offering is its use of virtual reality to help customers visualise a project before construction begins. Rather than relying purely on 2D plans or artist impressions, customers can experience a walkthrough of their proposed extension or conversion in advance, helping avoid the kind of late-stage surprises or design regrets that can affect a major building project.

Services

House Extensions

House extensions are designed and built to reflect each homeowner’s unique lifestyle, adding genuine living space rather than a generic add-on room. The team manages the full process, from initial design and structural work through to final finishing.

Loft Conversions

No1 Extensions and Conversions also carries out loft conversions, helping homeowners make use of existing roof space to create new bedrooms, offices, or additional living areas without the cost and disruption of moving house.

Garage Conversions

Garage conversions are a particular area of strength, with customer reviews describing garages successfully turned into utility rooms and downstairs toilet facilities, complete with thoughtful design touches suggested by the team along the way.

A Fixed Price Guarantee

No1 Extensions and Conversions offers a fixed price guarantee on projects, giving customers clarity on cost before work begins. Reviews specifically highlight flexibility around payment for any additional extras requested once a project is under way, alongside transparent handling of unexpected structural issues that occasionally arise once work has started — a genuinely honest approach to a part of the building trade that can otherwise catch customers out.

What Customers Say

No1 Extensions and Conversions holds a strong collection of detailed reviews on Checkatrade. One customer, who had their garage converted into a utility room and downstairs toilet area, praised Matt and his team for being punctual and genuinely clean, tidying up at the end of every working day, and coming up with design ideas the customer hadn’t considered themselves. Another customer described the finished result of their conversion as leaving them “over the moon,” while a further review praised incredible service from start to finish, with the team keeping disruption to a minimum and providing updates at every stage. One customer specifically noted having received quotes from three other companies, two of which didn’t respond, and one which questioned whether they actually “wanted things doing properly” — a contrast the customer felt made No1’s straightforward, problem-solving approach stand out even more.
