Architectural Design Services
We provide fully tailored architectural design solutions for residential projects including extensions, conversions, and new builds. Our services cover concept development, planning applications, and building regulation submissions. With expertise in integrating energy compliance from the initial design phase, we help clients achieve practical, cost-effective solutions that meet regulatory requirements while realising their vision.
SAP Calculations
Our SAP calculations ensure new dwellings and extensions meet Part L of the Building Regulations. Conducted at both design and completion stages, these assessments include energy performance evaluations and EPC production. We offer competitive rates for both standard and complex projects, including comparative SAP assessments for extensions exceeding 25% glazing-to-floor area ratios.
Dynamic Thermal Modelling (TM59)
We conduct CIBSE TM59 thermal modelling to demonstrate compliance with Part O overheating regulations. Using advanced 3D simulation software, we assess solar gains, heat dissipation, and ventilation strategies. Our assessments support design optimisation while maintaining architectural integrity, providing greater flexibility than simplified compliance methods for modern residential developments.
Measured Surveys
Our measured survey service produces accurate floor plans and elevations for existing properties. These detailed surveys form the foundation for renovation projects, extensions, or conversion works. We use precision equipment to capture existing layouts, ensuring all subsequent design work is based on reliable spatial data for improved project outcomes.
EPCs
We produce Energy Performance Certificates for new build dwellings and conversions. Our EPCs are lodged with building control to complete regulatory sign-off. The process includes both design-stage and as-built assessments, ensuring accurate energy ratings that reflect actual construction specifications while demonstrating compliance with current building regulations.
