About Us

A One-Stop Solution
As a privately owned family business we have continued to enjoy controlled expansion in specialist areas to service the needs of our clients.

Principal Contractor 
As a CIOB Chartered Building Company our Core business is the Role of Principal Contractor working for Public Sector Clients, Rail & Underground and private commercial Clients and architectural practices. We can demonstrate experience in refurbishment, new build and extensions.

We offer clients a one stop solution in that we manage and build the project from start through to completion. We highly value our staff and management team who have the wealth of experienced required to deliver our projects to the highest standard. Best Practice is perpetuated through our In-House CPD, CIOB and CITB training and apprenticeship programs developed over the years.

In order to save our clients money, create better budgetary and program control, we have integrated a number of Technical Specialties In-House.

These departments include;

1. Facades, Claddings & Specialist Renders.
2. Mechanical & Electrical.
3. Maintenance – Planned & Reactive.

Maintenance Services – Planned & Reactive
Our In-House maintenance department headed by Kieran Kelly carries out all manner of Reactive and Planned maintenance for many commercial Landlords and Public Sector Property Owners.

Green Technology
We are building a reputation for understanding and delivering projects utilising “Green Technology”.  Green Technology is the integration of the latest sustainable systems within the buildings fabric in order to reduce the buildings carbon footprint and in some cases carbon neutrality.  These high efficiency systems would include;

  • Ground Source Heat Pumps.
  • Underfloor Heating and Smart Control Systems.
  • Solar Panels / Photovoltaic cells.
  • High Efficiency, ‘Eco Friendly’ Insulated Render & Cladding Systems.
  • Green Roofs

We are keeping a close eye on government initiatives and looking at advancements into renewable resources and the need to protect and sustain the environment.  We have established a successful team through training and partnerships which we will support and develop and we see growing over time.

Project Management
We have established a project management team in response to the needs of some of our client base.  Our project management service provides the client with a resource, to provide a bespoke service to manage a project. Whether we are the Principal contractor or not, the project manager becomes the clients “eyes and ears” throughout the process, coordinating all aspects of the process.  The Project Manager provides specific focus on quality, budget and programme ensuring that the client is provided with the quality desired, within the budget approved and in the timescale agreed.
