We work closely with our clients, architects and structural engineers to find pragmatic ways of achieving their ambitions. We are less interested in ‘ordinary’ projects and more interested in creating ‘urban space solutions’ that provide extra value, space, light and pride of ownership.

Mono Ltd has been trading for more than 20 years and we believe we have an exciting  portfolio of projects that can inspire you to create something out of the ordinary.

Look at our project case studies and imagine what we could do for you.

We are now proud to be contributing towards offsetting some of the carbon emissions we make through our construction activities by planting each year around 680 trees – read more here.
