Excell Building have a great track record in making people’s dreams come true with professional house renovations. Homes need regular maintenance of course but sometimes they need just that bit more tender loving care. read more
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. read more
House extensions remain a popular way to increase living space and if you are one of the lucky London householders with a reasonable size garden, you could benefit by the addition of an extension, of one or two storeys. read more
Many London properties have basements, either semi-basements with windows onto a rear garden or the street, or spaces which are completely enclosed below ground level. Even those with windows are often damp, dark and a bit of a sad place which many families consign to storage. read more

The Professional Building Company

Nine out of ten of our clients come to us recommended by previous happy customers and we think that says it all. We have testimonials from many satisfied customers which we are happy to share with you and as you look through our website, you can browse pictures of some of our previous construction projects, so you can see just what we can achieve. We give a full twelve-month warranty on all our work such as loft conversions or house renovations, so in the unlikely event of it not coming up to standard in some way, we will make sure it gets put right. We’re not happy until you’re happy!

Specialist Building Services London

Give us a call to chat about the construction work you have in mind. We offer a full range of specialist building services in London of course, so whether you are thinking of a loft or basement conversion, an extension or a full refurbishment of your London property, we can help you get the home you have always wanted, quickly and reliably. Moving in London can be costly and if you have the location of your dreams, why not come to us so you can have the house of your dreams too? Space is often at a premium, but with so many London houses having extensive lofts and basements which are lying empty, don’t move, simply extend. We try to make our presence in your home as hassle-free as possible. Everyone has stories about living with builders but when you employ Excell Building, you won't have a long drawn out nightmare; you will have a great experience, ending with your perfect home.

Architectural Design

Successful architectural design starts with understanding the client’s vision and goals. We listen. Then we translate what we hear into designs that work for the client on every level — functionally, aesthetically, and financially. We offer clients a full range of architectural design services, from conceptualization through construction. Our office includes experts in sustainable design, code compliance, contract administration, building information modeling, and many other areas.


I thought Excell building was fantastic.They built a side-return extension and did a flat conversion for me.They delivered the project on time and on budget. They have a great team of people. Work was to a very high standard and I am delighted with what has been done. I would absolutely recommend them.

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.
