Services
Architectural Design
Our architectural design service creates bespoke solutions that balance aesthetic vision with functional requirements. Using 3D modelling and traditional techniques, we develop schemes tailored to site-specific contexts while prioritising sustainability. With expertise in residential, commercial, and community projects, we ensure compliance with planning regulations and heritage considerations across Cornwall and the South West.
Sustainable Architecture
We specialise in sustainable building practices including Passivhaus standards and low-energy housing. Our approach reduces environmental impact through material selection, energy-efficient systems, and passive design principles. This service integrates renewable technologies with traditional architectural methods to create healthy, cost-effective spaces that meet UK sustainability targets while maintaining design integrity.
Planning Applications
Our planning expertise navigates complex regulatory frameworks for residential and commercial developments. We prepare detailed submissions including feasibility studies, heritage impact assessments, and 3D visualisations to support successful approvals. With strong local authority relationships, we manage listed building consents and conservation area applications across Cornwall's protected landscapes and urban centres.
CGI Visualisations
Photorealistic computer-generated imagery brings architectural concepts to life during the design phase. This service enables clients to visualise spatial relationships, material choices, and environmental interactions before construction begins. Our visualisations support planning applications and client decision-making while maintaining technical accuracy for construction documentation.
Construction Management
We provide comprehensive contract administration from tender to completion, ensuring adherence to design specifications and budgets. Our site inspections monitor workmanship quality while coordinating contractor communications. This service includes payment certification, variation management, and final account preparation, guaranteeing projects meet RIBA Chartered Practice standards for delivery and client satisfaction.
