Architectural Design
Our architectural design service combines creative vision with technical precision to deliver functional, aesthetically pleasing spaces. We work across sectors including education, healthcare, and commercial, using BIM technology and 3D visualisation tools. Our RIBA-chartered architects collaborate closely with clients to create sustainable, future-ready buildings that meet exacting regulatory standards while exceeding user expectations.
Heritage Conservation
Specialist heritage services include conservation, restoration, and adaptive reuse of listed buildings and World Heritage Sites. Our AABC-accredited team provides condition assessments, planning applications, and sensitive design interventions. We balance historical integrity with modern functionality, ensuring compliance with heritage regulations while enhancing building usability for contemporary needs.
Masterplanning
We create strategic masterplans that shape sustainable communities and guide development. Our approach integrates land use analysis, infrastructure planning, and stakeholder engagement. Services include site analysis, phasing strategies, and 3D urban modelling. We prioritise connectivity, environmental sustainability, and long-term economic viability in both public and private sector projects.
Principal Designer Services
We provide CDM 2015 Principal Designer services ensuring health & safety compliance throughout construction projects. Our team coordinates design risk management, pre-construction information, and client duty support. With PAS 8671-compliant competence frameworks, we help clients meet legal obligations while maintaining design quality and project efficiency.
Feasibility Studies
Our feasibility studies assess site potential, regulatory constraints, and financial viability. We deliver detailed reports covering planning strategy, budget estimates, and procurement options. The process includes stakeholder consultation, risk analysis, and concept design options to establish clear project parameters before detailed design begins.
