TAILORED CONVERSION STYLES
The most popular loft conversion in the UK, a rear dormer extends vertically from the back roof slope to create extra headroom and usable space. It may be built from the rear wall or slightly set in to meet council regulations.
REAR DORMER
MANSARD
Built at the rear (or sometimes front), with a flat roof and steep rear wall to maximise internal space. Requires planning permission.
HIP TO GABLE
Extends the sloped side of a hipped roof to form a vertical gable, creating more usable loft area — ideal for semi-detached homes.
L-SHAPED DORMER
Combines two dormers — one over the main roof and one over the rear — forming an L shape. Great for larger loft layouts.
PIGGY BACK
Raises the perimeter walls and rebuilds the roof to add significant height and space — ideal for a more open, practical loft.
VELUX
Keeps the original roof intact, adding skylight-style Velux windows to bring in natural light. Minimal structural changes needed.
THE HOLLIES
ATTENTION TO DETAIL

5 STAR REVIEWS
I had a great experience using LMB Ltd. Joanna and T held my hand throughout the whole process. The site Manager was amazing. I recommend LMB because they were professional throughout with excellent after care.
"An excellent service by an excellent organisation. LMB delivered out loft conversation and provided two rooms and a shower room. Right from the start we received a managed service with Ricki’s advice and assurance, through to the design and construction; we were looked after and well informed. Everyone involved brought a smile and went out of their way to help us, including the team in the office giving updates and ensuring we felt great."

LMB did a loft conversion for us. We had a few teething problems regarding the planning permission phase, but once we sorted those out, the work done was really good quality. The builders were extremely reliable, trustworthy and tidy- I was really surprised there was almost no mess internally (we stayed in our house during the work).
All the tradesmen delivered high quality work and were overall very reliable on timings. They were also very trustworthy.
LMB were responsive to us throughout about any issue we raised. We are really happy with the end result. Would recommend
LAURA HICKLEY
LMB carried out our loft conversion in Spring/Summer ‘24. The build was more complicated than a standard conversion, due to needing to both drop some of the 1st floor ceilings, alongside carrying out a hip to gable conversion. Despite the added complexity, LMB were able to carry out the works with minimal disruption, all while we still lived in the house with our young kids. All the builders and tradesmen were courteous and caused no issues with our neighbours throughout the works.

We offer a trade discount with Topps Tiles, but we can also
offer you an appointment with their boutique showroom using their visualiser software.
We work closely with door manufacturers and we are able to provide a
quotation for upgrades to other doors, handles or furniture to achieve
the final look you want.
LMB install over 200+ velux windows a year and we are delighted to be
able to offer you a full blind ordering and fitting service to accompany your
new windows.
In time, you may find a felt flat roof can pick up moss and algae; the synthetic rubber doesn’t support the growth of moss so you are guaranteed a clear roof!
LMB were great from start to finish. For what could have been an incredibly stressful time, LMB made my experience of a major building project relatively painless. Yes, there were issues, which anyone would expect on such a venture, but LMB were quick to respond and put things right (even going as far as sending flowers to my neighbours to apologise for excess noise from the scaffolding).
PATRICK TATE
Very happy with the finished article of our loft conversion. Tradespeople were pleasant to deal with, particularly the builders, plumbers and tiler. Ollie the project manager was very reasonable and good to work with, as was Philomena in the office. Communication was all done by WhatsApp so everyone knew what was happening. Was amazed how the staircase was able to fit in the space we had, very clever design. Split the loft into two bedrooms and pleased with the space it gave us. Well worth the money considering the extra space and added value to the property, would recommend to anyone considering.
