LLAC loft conversion
We were impressed and appreciative throughout the loft extension to our north London terraced house, which has given us two splendid new bedrooms and a shower room. The quality and professionalism of the work carried out was top standard and the LLAC team was at all times responsive, understanding and helpful - also adaptable and flexible whenever the inevitable snags cropped up. They made it all go smoothly and minimised the disruption. The core team was excellent as were the various traders – carpenter, electrician, plumber, plasterers – who played their part with the same approach as the core team. LLAC also kept strictly to the agreed budgets. We recommend them for anyone looking for home extensions.

LLAC did a great job on my loft conversion, which was done within a conservation area. The tradespeople were skilled, reliable and considerate. I would recommend using LLAC for others conversions.
Fantastic Loft Conversion by LLAC
LLAC was recommended by my neighbour, and now I can see why. They mainly work through word of mouth because of their good reputation. The whole team was great communication was clear, and everything went really smoothly from start to finish.
Aneliese, the senior design consultant, was very attentive and even replied to my questions while she was on holiday. David, the contractor, was patient and helpful, especially when I started to panic during the project. The staircase they fitted looks amazing, and the overall finish is lovely, complete with a 10-year warranty. They finished the work on time, even during the busy summer season. I’d definitely recommend LLAC to anyone thinking about a loft conversion or other building project.
Dormer loft conversion
They did our loft and completed it on time. The workmanship is excellent and very professional, and the 10-year warranty is definitely a bonus. The team was friendly and easy to deal with throughout the project. We had a few disagreements along the way, but everything was handled with great professionalism and care. I’d highly recommend them for your next project
Exceptional
Exceptional on price, and sticking to the price quoted, on the build quality which is superb, and on the timescale… which was accurate to the day. I would highly recommend LLAC.

Extensions N8
Over the last 18 months, we have had 2 large building projects carried out by LLAC. The first project was a loft conversion to provide a bedroom and ensuite bathroom. (This included provision of a new roof to the property.) The second was a rear extension to provide a large kitchen with internal utility room and cloakroom. (This included removal of a chimney breast.)
The team were very reliable, hard working and communicated well with us. Any issues were discussed as they arose and any problems quickly solved. At the start of the works, we were provided with a detailed quote and timeline. The works were completed on budget and within the expected time frame.
We would very happily work with LLAC again and thoroughly recommend them.
Roof extension, kitchen and rear extension
Roof extension, kitchen and rear extension in N19, London: Hard working and efficient. Any issues that came up they returned to sort out. They have a team of people they call on for most aspects of a project, and offer recommendations for any specialist parts.
Fantastic loft conversion
We worked with LLAC in 2023 on a loft conversion in our terraced house in North London. We had a fantastic experience from start to finish. This was our first time undergoing building works and we were a bit nervous going into it (we've all heard the horror stories of builders not showing up for days on end and costs spiraling out of control) but we had no need to worry. After meeting Aneliese and Ylli, who oversee all their projects, we knew we were in safe and competent hands. Ylli has a wonderful, calm manner and was able to talk through all our questions and put us at ease. LLAC were reliable, hard working, able to troubleshoot any issues that arose in a thoughtful and pragmatic way, and incredibly easy to work with. The team that was on site running the day to day was led by the lovely Mikel. They showed up at the same time every morning, worked incredibly hard, finished within the quoted timeframe to a very high standard, and delivered on budget. We are absolutely thrilled with our loft conversion. We have recommended LLAC to a number of friends and neighbours and will absolutely work with them again in the future if/when we have any further building needs.
Loft converstion
LLAC converted our loft into living space and the results were outstanding. The size and layout of our attic meant space was limited but LLAC managed to make the most of what was available giving us more space and ceiling height than we expected. The on-site team were fantastic and really helpful in making sure that our specific requirements for the external and internal design were achieved. The work was completed on time and on budget.
Very happy
LLAC did a brilliant job on a kitchen extension for us. Not only was Ylli, the Project Manager, brilliant but every single person that came to work at the house (whether recommended by LLAC or working for them) was quick, professional, friendly and did a great job. We’re very happy and would definitely recommend them.
Loft conversion. Quality not good.
LLAC built a loft conversion in my property. The guarantee for the works is 10 years. Soon after the works were finished I had problems: water leaking in through the roof, insulation (Kingspan) missing and guttering installed wrong, leaking water into the wall. When I contacted LLAC for their responsibility, they would not accept liability. Unfortunately I can't recommend this company to other folks.

Exceptional work
Very very happy with the great extension built by LLAC . They were extremely helpful and understanding of a very difficult architectural project.
Would not hesitate to recommend them.
We are very happy with our loft conversion
We are very happy with the work carried out on our loft conversion by LLAC. They finished on time, in budget and the work is of a very high quality. I found I did slightly more hands on project management than I anticipated (communicating timing between e.g. plumber and tiler) but overall does not detract from satisfaction level of work done. Good communication, reliable invoicing and could always get hold of someone when I needed them.

We met with aneliese from LLAC for an initial quote. Aneliese is a design expert and had some wonderful ideas that we had not thought of to save space and make our finished project more beautiful.

I have chosen LLAC as a couple of neighbours had recommended them and I’d seen the great job they did in their houses. Ylli, Genc and all the team were professional, had working, considerate and trustworthy. I’ve added some ideas for loft conversion, and they executed them perfectly. I recommend them 100%
I decided to go with LLAC construction…
I decided to go with LLAC construction because they did few loft extensions in my street and my neighbours recommended them. I am glad I made the right choice and now, I am very happy with my new loft and ensuite wet room. Genc, Ylli and all the team were always there to answer any queries and managed the whole process with total professionalism. The work took around 6 weeks in total to complete which was great. I would definitely recommend LLAC to anyone. Thanks again for a fantastic job!

We had our loft conversion done just few months ago and are very happy with the result. The quote was very clear, and all extras spelt out to us so knew exactly what to expect. The plans, application & building control was all taken care of, we didn’t have to do a thing. The build itself was excellently handled by Ylli, Genc and his team. All his team were very professional and hard working. The office team were very friendly as well and respond quickly to any queries we had. We would highly recommend LLAC
Fantastic job
We recently used LLAC to build an extension and loft conversion for us. Fabulous company to work with, they did a fantastic job. Many good suggestions and implementation of our ideas. We are extremely happy with the results and would without question use them again. We are more than happy to recommend them and in fact, we have already referred them to a number of our friends and family.

Many thanks to LLAC team and Ylli for providing a complete service along with advice, suggestions and practical solutions. I can highly recommend LLAC who worked incredibly swiftly and conscientiously.
