Services
Home extensions
We design and manage residential extensions that enhance living space while maintaining architectural integrity. Our process includes measured surveys, concept design, planning applications, and construction oversight. Clients benefit from our expertise in maximising natural light, optimising layouts, and securing planning approvals for both modern and period properties.
Property renovations
Our renovation services focus on transforming existing spaces through intelligent reconfiguration and modernisation. We handle full-house renovations, kitchen and bathroom upgrades, and structural modifications. With specialist knowledge of period properties, we balance heritage requirements with contemporary living needs while ensuring compliance with building regulations.
New build homes
We create bespoke new homes tailored to client specifications and site conditions. Services include site analysis, concept design, planning submissions, and construction management. Our approach prioritises energy efficiency, sustainable materials, and seamless integration with surrounding environments for both rural and urban developments.
Planning applications
We manage the entire planning process for residential developments, including pre-application consultations, submission preparation, and local authority liaison. Our success rate reflects deep understanding of local regulations, conservation requirements, and effective presentation techniques to secure approvals for complex projects.
3D visualisation
Our virtual reality walkthroughs and 3D printed models allow clients to experience spaces before construction. This technology aids decision-making, clarifies design details, and helps identify potential issues early. These tools form part of our commitment to transparent communication and client involvement throughout the design process.
