The first thing we build is trust

Experience tells us that attention to detail is paramount within a building project.

Listening to our customers

We treat all our customers as individuals. Some clients have had experience with prior building works and some are embarking on their first project. Each customer has their own unique range of questions and specifications that will need detailed analysis and discussion. 

We pride ourselves in listening to customers’ needs and helping them develop the project to best suit them and their families. Listening to our customers and providing guidance when asked also helps keep the customer completely informed and satisfied with the direction of work during the build.

Our experience in planning, design layout and construction budgets can save you money that can be best spent on direct build costs.

Teamwork and communication

Many customers come to us already working with a group of building professionals such as architects, structural engineers and surveyors. For other clients, we can call on our own architects and structural engineers to assist them with a comprehensive “Design and Build” package that we offer. 

In either case, we like to take the lead role in fostering clear communication, coordination and teamwork across all parties.

Whether we work with your design team or ours, our aim is to ensure that you have the right design and then give you a clear time frame, well planned process and detailed quote with which to manage your project.

We’ll get back to you

Smart Build is different

Other builders think of construction projects as just a series of building trades on a site. We know that to succeed takes more skill, vision and commitment than that.

Smart Build excels at seeing projects through from the early design stages to finished build, while all the time maintaining good communications, flexibility for design changes and control of timescales and budget.
