Our business was founded by Mark Johnston and Nicola Slater. Senior-level operations, construction delivery, sales and client relationship specialists.

What we do

We believe there is a better way to deliver a construction project

Our services provide clarity, objective insight, and innovative solutions to deal with a range of problems, we work with you throughout every step of the process.  There is a largely unfair belief in the construction sector that projects are rarely on time and that quality is often substandard. We know that it does not have to be this way and that issues with construction projects come not from a lack of standards or skill, but from ineffective process management and collaboration along with poor visibility of activity.

Our solution is to provide expert advice, bespoke support, Construction Project Review, and hands-on assistance throughout the construction project management process – from initial consultation and feasibility studies through to completion. 

Our team consists of highly knowledgeable, hand-picked construction professionals with an in-depth understanding of the UK construction industry and the built environment. 

We are genuinely passionate about the construction industry and helping our clients deliver projects with 100% customer satisfaction.

Whether you’re an established construction company or a client concerned about progress, we have the knowledge and experience to ensure that your project is completed successfully and with positive outcomes for all.

How we improve construction project outcomes

Our services include bespoke construction consultancy, training and development support, construction project reviews, improving process, and more – whatever you need to achieve the best outcomes and smooth project completion.

Cube is committed to providing our clients with the highest quality construction guidance and consultancy, and work hard to ensure that your construction project is completed on time and within budget.

Why we do what we do

Process planning and implementation with Cube has given us an independent evaluation, with top-level end-to-end oversight of the operational aspects, minimising risk and helping ensure our projects are delivered on time and within budget.

Cube’s hands on practical and collaborative approach made them the ideal choice to lead the Maltby team to a successful outcome. This project has realised the ambition of the Trust and provided a community facility that will bring education, employment and training together under one roof.

We have not only used Cube for our business process review, we have also asked them to share their knowledge and experience to support our internal teams on complex, business critical projects. We have no hesitation in recommending them.

Cube has talent for making connections and bringing people together to create opportunities.

Cube has brought a professional level alternative to embedding a business development skill set here at EDGE, that has already brought us valuable results.

Through an established network of contacts, Cube was able to quickly identify the areas where we had significant crossovers in our sector expertise. Nicola coached the team to capitalise on these opportunities and to highlight new avenues for marketing based on our relevant skills, objectives and people focused approach.

Cube has been fundamental in providing the guidance and advice needed to get our tender submissions to the highest standard which has ultimately led to successful appointments.

Cube have continued to work seamlessly with the team at various stages in the build process on high profile projects, providing objective assessments for their effective delivery.

Cube consulted openly with our teams’ leaders to identify the process requirements that best suited our business model. The process has resulted in our teams having one clear and identifiable management system. The benefits are visible from our preconstruction process through to project delivery.

Following Cube’s recommendations, we were able to avoid project challenges and proactively implement positive change measures within our team to deliver a success outcome for our client.
