Exceptional Renovations with Unparalleled Expertise in Basement Conversions & Listed Buildings

OLBC has a long and distinguished history, providing solutions for discerning clients in London and the Home Counties.

However, OLBC is not driven purely by project value, it is more about project fit.

OLBC offer clients a truly bespoke, turn-key construction services, from structures, architectural design, planning and listed building consents, construction and project management, right through to interior design and furnishing or even our exclusive special projects.

We differentiate ourselves by only taking on a very small number of projects simultaneously, usually a maximum of five at any one time and using our own time served staff.

If you are considering a project we would be delighted to hear from you – please email us, call us on 0208 877 0526 or fill in the short contact form [at the foot of the page] or use the green WhatsApp button on the top of the page and one of our experienced team will be in contact to discuss your project.
