Our Process for Home Renovation & Extension Projects
For most projects, we simplify the architectural journey into (3) three major steps, aligning with the RIBA Stages. This approach ensures clarity, flexibility, and a seamless experience at every phase:
1. Design and Planning (Stages 0-3)
We define your vision and develop design concepts, ensuring alignment with your needs. This stage includes planning and securing necessary approvals.
2. Technical Design and Tender (Stage 4)
We create detailed technical drawings and specifications, ensuring clarity and precision for construction, working with your contractor to align everything with the design.
3. Construction and Handover (Stages 5-7)​​
We oversee the process to ensure the renovation is executed as planned, collaborating with the contractor to meet your expectations and ensure the final result aligns with your vision.
This structure allows us to provide a comprehensive service while giving you the freedom to engage with each stage independently, based on your comfort level and budget.
