Great buildings deserve to be loved.

At Solid, we care about the work we do. We provide the practical basis for construction so that fabulous buildings, from listed landmarks to state-of-the-art new homes, get the attention they merit.

+ Our work ranges from…

...simple alterations to complex major new projects. Whatever the brief, our approach is open, flexible and collaborative; from reporting on defects to providing integrated engineering solutions as part of a multi-disciplinary team.

We produce practical, elegant, design-led solutions and when deadlines are short, we work quickly while maintaining attention to detail.

We explore material options, construction techniques and procurement processes, setting out our designs visually and sharing our ideas, from concept to construction.

Architects and clients can trust our ability to explore ideas fully; safe in the knowledge we will remain loyal to project needs.


Infrastructure brings projects to life.

Whether through a new sewer connection or a site appraisal, development-wide highway master planning or sustainable drainage design; we deliver engineering solutions that help unlock a project’s potential.

+ We work with clients to…

...develop conceptual designs, informing and supporting planning and bid processes, through to detailed design, construction and operation.

Across greenfield, brownfield and live sites, we identify critical risks and constraints, providing crucial information for both planning and pricing.

We design roads, car parks and driveways for residential and commercial developments deploying vehicle movement simulation and terrain modelling. We have experience in providing Transport Assessments, Transport Statements and Travel Plans for a wide variety of developments.

Using MicroDrainage software, we model existing and new surface and foul water drainage networks and design cost-effective sustainable drainage systems. We also design water-harvesting systems and prepare compliant flood risk assessments.

We design drainage treatment systems for a range of site uses and have full understanding of procedures and requirements to ensure timely approval of relevant permits and discharge consents.

Our external work design includes calculating external levels, designing retaining walls and soil retaining for hard and soft lanscaping works.


Building information modelling - BIM - adds value to the construction process but it doesn’t have to be complicated.

We work hard to understand the client’s perspective and expectations, and use plain language to address concerns - is the construction affordable? Is it likely to receive statutory approval? How long will it take?

+ Having the right team in place and…

...setting out the information requirements and responsibilities at the outset is crucial. Whether you’re new to BIM or a veteran, we’re happy to contribute at an early stage. We’ll keep it simple and, if it helps, sketch it out.

BIM itself is not a destination. At Solid, we’ve been developing our use of BIM for more than a decade and we’re committed to learning more and enhancing our understanding further.

We continue to invest in our capability and hold regular training workshops to sharpen focus and share best practice. The main software programme we use is Allplan Engineering - the integrated BIM/CAD software for structural and civil engineering.

Through the use of BIM, coupled with our commitment to developing skills, we continue to find ways to build value into the construction process.

Specialist design

Problem solving is easier with effective communication.

At Solid, we pride ourselves on being good communicators. We bring knowhow and enthusiasm, solving problems with simple sketches and the latest in 3D modelling software.

+ By understanding a particular set of complex problems and…

…then communicating the solutions in a way that makes sense, we have developed a number of areas of specialist design.

Stone staircases

Since 2005, we have completed the design of more than 60 stone staircases throughout the UK and Ireland, in materials ranging from soft limestone to harder limestone, marble and yorkstone. We offer a full design service from initial concept through to construction.

Stone facade engineering

We provide independent stone facade engineering for traditional and contemporary stonework, and we are as comfortable with traditional architectural detailing as with contemporary facades and modern design methods. We are often invited by architects to contribute to designs at an early stage to help establish design principles and certainty of concept, but we are equally happy providing detailed fixing design at construction stage.

Green oak

We understand the material characteristics and traditional detailing of green oak frames, as well as modern laminated oak and beech and clean contemporary detailing.
