Services
Architectural Design
Our architectural design service creates innovative, cost-effective solutions tailored to client needs and site constraints. We specialise in both modern new builds and sensitive historic building conservation. From concept sketches to detailed construction drawings, our RIBA Chartered Architects ensure aesthetic appeal and functional efficiency while maintaining compliance with planning regulations and building standards.
Structural Engineering
Our in-house structural engineering expertise delivers technically sound solutions for residential and commercial projects. We provide comprehensive structural calculations, beam sizing, and foundation design. Our engineers work closely with architects to ensure seamless integration of structural requirements with architectural vision, particularly for complex projects involving listed buildings or challenging sites.
Planning Applications
We manage the entire planning application process, from initial feasibility studies to submission and council liaison. Our team has extensive experience securing approvals for extensions, new builds, and conservation projects. We prepare detailed drawings and documentation that address local authority requirements while maximising development potential within planning constraints.
Building Regulations
Our building regulations service ensures projects meet all statutory requirements. We prepare detailed technical drawings and specifications covering structural safety, thermal performance, and accessibility standards. We coordinate with approved inspectors or local authorities to achieve compliance efficiently, minimising delays during construction.
3D Visualisation
We create photorealistic 3D visualisations and digital models to help clients visualise projects before construction. This service supports design development, planning applications, and client presentations. Our BIM-capable software enables accurate spatial analysis and clash detection, improving project coordination and reducing construction risks.
