A bit about what we do...

Design and Build Construction

We believe respectable and transparent communication is key whether that is in the process of building your dream home or simply helping you achieve this with extensions or refurbishment. We will support you from your initial idea starting with planning and building control, then all the way through the construction of your dream project.


Our specific expertise in structural waterproofing ensures your home receives comprehensive protection against water ingress, moisture and structural damage. We provide customised waterproofing solutions for your individual needs, corporate or residential, to avoid water and humidity damaging your buildings thus leaving them protected for greater longevity.

Estate Management

We understand how buildings work and what makes the communities within them flourish. From blocks of flats and housing estates, it’s our job to keep the homes we manage comfortable, well cared for and their communities a great place to live.. We will be managing repairs, maintenance and all minor to major work that is needed or requested.
