We Provide Loft Conversion and Extensions in London

Welcome to Excell Building Loft Conversions

Excell Building are loft conversion specialists and have many satisfied customers across south west London. London gardens are often not very big and it seems a shame to cut into them further to give much needed extra space, so a loft conversion is often the best way to give more room for a growing family. Excell Building provide a full loft conversion service from initial design to completed project so there is no need for you to source subcontractors or to deal with anyone else – we are a one-stop-shop for your fabulous new loft conversion.

London Loft Extension Specialists

Many people who would benefit from a loft extension or conversion are put off because they have heard horror stories from friends and work colleagues of such projects taking months on end and turning the house into a building site. These may be true, but not if you use Excell Building. We make sure that we roster the job so that we are not constantly coming and going – the main reason that some jobs take a long time – and we prefer to work in a neat and methodical way, so you don’t get piles of dust and rubble cluttering your house for ages either. When you see the wonderful new rooms a loft extension can create, you’ll kick yourself for not acting sooner.

What extra rooms would you like?

If you are not familiar with what can be achieved with a London loft conversion, come and talk to us. We also have a portfolio of previous projects for you to look through, so you can see just what can be done. Whether you want a luxurious bathroom, a new bedroom or study or even a suite of rooms for a growing teenager, you will find that the wasted space under the roof is ideal. You don’t have to move, your garden stays intact and all you get is more room, not a lot of hassle and upheaval. When it is all done and you are enjoying a nice wallow in your brand new bathroom, you’ll be glad you came to Excell Building for your south west London loft conversion.

Excell building was recommended by one of my close friends and I wasn't disappointed. They came up with creative solutions for us to stay on budget. The whole process went smoothly, was handled cleverly and delivered on time. I am happy to give my recommendations at any times.

I am not easily pleased. And I had been warned that working with builders was so often a nightmare, I should prepare myself for it. I have to say, it was absolutely nothing of the sort. I was doing an entire renovation project, knocking down walls, new kitchen and bathroom, the works. And the Excell team did a fantastic job. The standards were supremely high, the guys were helpful, and Yuriy the project manager was absolutely reliable and excellent to work with. Since then, I have recommended them highly to friends and colleagues. I have also heard so many horror stories in recent months that I do feel pretty blessed for finding such great builders.
