We are experts in building services, helping our clients to design and fit out well-constructed, comfortable and sustainable environments. We help to ensure long-lasting gains across a building’s lifecycle.

We offer varying design approaches to meet any project and client requirement, including design and build and expert detailed design services.

Ensuring designs meet Building Regulations is the start. We can help to ensure your developments exceed end user expectations, designing in energy efficiency to ensure buildings are sustainable and efficient from day one.

Uniquely, we can also draw on the resources and expertise of our sister companies in The Consultus International Group. No other design consultancy can look at the real-life usage of similar buildings when developing designs. Every day, Consultus companies are helping organisations to reduce costs, optimise operations, comply with legislation and work more profitably.

Who we work for

We work UK-wide with landowners, builders, developers, construction companies, major manufacturers, building owners, facilities teams and contractors. Combining a background in construction, utilities and sustainability with experience across the spectrum of residential, commercial and mixed use projects, including refits and refurbishment, our people speak the same language as stakeholders and design teams.

Our experience enables our team to design for projects in all sectors, including manufacturing, retail, healthcare, education, government, transport, leisure and hospitality.

A complete service

Our expertise means we can support building and development projects from the earliest pre-planning, concept and design stages. You can achieve new value and support the smooth running of projects by writing your high-standard design details into the specifications given to builders and contractors. Indeed, we can help you to embed best practice in building design and flexible sustainability strategy at the heart of your development, benefiting all stakeholders.

We work in whichever ways our clients need: design and build, or detailed design. The approach taken can depend on the type of development project and what a client needs, with each one having advantages and disadvantages.

However, experience has shown that the earlier a building services consultant is engaged in the design stage, the more value can be gained: from securing a more accurate tender cost for a project, as this reduces uncertainty in design and removes opportunities for a contractor to charge for variations and additional costs, while ensuring high design standards and embedding them in technical specifications to deliver the best outcomes.
