Start-Up Flexibility, Big Company Expertise

As a UK-based start-up, we combine the energy and flexibility of a small, agile team with direct access to senior engineering expertise. We’re responsive, collaborative, and free from rigid processes, allowing us to tailor our approach to each client and project. Our size means we stay close to the work, ensuring quality, efficiency, and genuine commitment on every brief. From new builds to heritage refurbishments, adaptive reuse, industrial units, data centres, hotels, commercial spaces, residential developments, and fit-outs, our combined experience spans a broad range of construction projects. Our commitment is simple: to deliver tailored advice and specialist services, whatever the nature or scale of your project.

Efficient, Responsible, Resilient

Minimise intervention. We promote lean design, modern materials and construction techniques, and using them as efficiently as possible. It is our objective to maintain sustainability at the forefront of the discussion, and we will bring our expertise from the pre-planning stage to avoid missed opportunities. We look after our environmental and social impact,  operating under the IStructE Structural Plan of Work and our processes follow the IStructE sustainability checklist and resource map.

Support Throughout all Stages

We support our clients through every stage of the project lifecycle. From audits and feasibility assessments, to pre-planning support, design, delivery, site support and Client monitoring. Our team offers comprehensive expertise across all stages to ensure a successful outcome. We offer a holistic understanding of each project, regardless of our role, to ensure we meet the project's objectives with precision and care.

Led by Design

Placing creativity and innovation at the forefront, we believe in true collaboration with architects, designers and other stakeholders, to achieve a seamless integration of the structural aspect with the aesthetic and functional goals. Design Box promotes technical expertise, effective communication, attention to detail and flexibility to navigate the dynamic nature of design-led projects and respond to their evolving requirements.

Shaped by Context

Drawing on our experience in both London and Paris, we bring a deep understanding of the urban context and the complexities of working within dense, constrained environments. We take a site-specific approach, identifying existing conditions and constraints early on, and working closely with clients, project managers, and design teams to develop tailored strategies. Our proactive engagement with asset owners ensures that key challenges are addressed from the outset, enabling smoother project delivery.

Consultancy

At its core, our practice is built on consultancy. We see structural engineering not just as technical design, but as expert guidance rooted in a deep understanding of structures and how they interface with other specialisms. We focus on delivering clear, considered advice that helps our clients make informed, confident decisions throughout the life of a project.

Clear deliverables

Clarity is at the core of successful collaboration. We define project deliverables early on through open discussions with clients and stakeholders, setting clear expectations from the start. Internally, we follow structured templates and procedures to ensure consistency, quality, and coordination across every stage of the project.

Appropriate tools

We design and deliver using industry-standard tools, but also embracing innovation. However, our most valuable assets are sound judgement and practical experience. We keep things simple when they can be, and get sophisticated when we have to. Above all, we maintain a critical and thoughtful approach to ensure each solution is fit for purpose.

Sustainability

We understand the environmental impact of construction and the role structural design plays in shaping it. With structure often responsible for a significant share of embodied carbon, we focus on lean, efficient solutions. Our team stays informed on low-carbon materials and circular design strategies, working closely with clients and architects to reduce carbon wherever possible.

Confidentiality

Discretion is essential on certain projects, whether due to commercial sensitivity or regulatory requirements. We handle all information with strict confidentiality, backed by secure systems and GDPR-compliant processes. Our team follows robust data protocols and non-disclosure agreements to protect client interests at every stage.

Engagement

We believe that empathy and collaboration are key to successful projects. By taking a holistic view of the built environment, we foster open communication and shared understanding from the outset. This helps us interpret the brief clearly and work together to develop solutions that are thoughtful, responsive, and well aligned with project goals.
