Services
Architectural Design
Our architectural design service creates bespoke solutions balancing aesthetic appeal with functional efficiency. Specialising in new builds, extensions, and adaptive reuse, we employ 3D modelling and traditional drafting to realise client visions. Projects range from contemporary residential developments to sensitive heritage interventions, always prioritising sustainability and regulatory compliance.
Building Surveying
Comprehensive building surveying services cover condition assessments, dilapidation reports, and quinquennial inspections for residential and commercial properties. We provide detailed analysis of structural integrity, maintenance requirements, and compliance with building regulations, particularly for historic and listed buildings requiring specialist care.
Heritage Conservation
Specialist heritage conservation addresses Grade I/II* listed buildings and historic estates. Our approach combines traditional craftsmanship with modern techniques to preserve architectural integrity while implementing necessary upgrades. Services include Listed Building Consent applications, joinery details, and collaboration with Historic England for sympathetic alterations and reuse projects.
Sustainable Design
Sustainable design integrates low-carbon principles across projects, from fabric-first approaches to renewable energy systems. We deliver energy-efficient solutions like air-source heat pumps and SAP-certified Passivhaus standards, reducing CO2 emissions by up to 76% in recent school retrofits while maintaining aesthetic and functional excellence.
Passivhaus Certification
Passivhaus services encompass design, certification, and construction oversight for ultra-low energy buildings. Our team includes accredited designers with hands-on experience in achieving 0.37ach air tightness standards. We apply these principles to both new builds and retrofits, ensuring optimal thermal performance and occupant comfort.
