We use only trusted materials and expert building methods to ensure each conversion stands the test of time – both in structure and style.

Every project is uniquely tailored to your space, your lifestyle, and your vision – from initial consultation to the final finish.

We offer tailored services in:

Cellar conversions

Basement waterproofing

Structural waterproofing

Damp proofing and tanking systems

Full design and planning

Compliance with building regulations

Every project starts with a detailed site visit to assess your current basement or cellar, its headroom, structure, and the potential to add value to your home.

Why Convert Your Damp Cellar?

A damp cellar or underused basement can often be overlooked, but it has the potential to become one of the most valuable parts of your home. From a simple storage area to a full new living space, converting your cellar is a fantastic way to add functionality, comfort, and resale value.

With modern basement waterproofing techniques and a robust damp proofing system, we can convert your damp underground room into a bright, welcoming environment.
Whether you want a guest suite with an en-suite shower room, a media room, or a creative studio, we’ll work closely with you to transform your basement to match your lifestyle.

A Unique Space Tailored to You

We believe no two basements are the same. That’s why our team at JM Lee takes a bespoke approach to each and every conversion.

Whether you’ve got an existing cellar crying out for a refresh or want a full basement dug beneath your home, we’ll develop a tailored plan that aligns with your vision and budget.

Looking for a wine cellar to showcase your collection? Or maybe a shower room to accompany your new guest suite? From luxury finishes to practical touches, we’ve got you covered.

A Conversion That Meets Building Regulations

Every conversion we undertake is built to meet or exceed current building regulations. Our team collaborates with structural engineers and architects where needed to ensure your new basement or converted cellar is not only safe but also maximises its full potential.

We handle every detail, from:

Planning applications (when you need planning permission)

Technical drawings

Drainage and insulation

Electrical and plumbing setup

Finishing touches to create a true extension of your home

No cutting corners – just superb conversions done properly, with care and precision.

Can’t recommend Steve and his team enough, they are exactly what you hope you’ll get when you use tradespeople. Fantastic communication, punctual, friendly and an excellent work ethic. Steve helped us work within our budget and has been incredibly accommodating, cannot fault the team at all. If you’re thinking of having any work done on your basement/cellar then I would definitely recommend them.

★★★★★

If you’re looking for a cellar / basement conversion they don’t hesitate to give Steve a call. All basements come with challenges but Steve and his team are fantastic. From start to finish the job was planned and executed perfectly. Good communication, never lets you down and is very transparent about timelines and cost. They take a real pride in the finish. They are also a top bunch of blokes which is important if they are going to be in your home (or underneath it) for several months).

– Martin Kirkham

★★★★★

Fantastic experience from start to finish, Steve and his team are knowledgeable and efficient. Not to mention incredibly patient with all the questions I had about the process.

I approached numerous businesses before making this decision and I do not regret a thing. I explained my usage and need for the cellar and RM Lee Cellar Conversions have gone above and beyond in their work. Fantastic work, great team and a more than reasonable price. I Highly recommend.
