Proposed plan for single-storey extension in Cardiff by AEM Stiwdio
At AEM Stiwdio, we delivered a tailored design for a single-storey rear extension at a residential property in Cardiff, focused on maximising open-plan living, natural light, and functional flow.
The extension includes a new kitchen-diner space with large-format glazing and improved garden access. Planning permission was successfully achieved through close collaboration with the local authority.
This design enhances usability and value while fully complying with UK Building Regulations and Cardiff Council planning policies.
🏗 Project Overview
Our approach focused on Phase 1: Rear Extension, designed to enhance the internal layout and create more spacious, regulation-compliant living accommodation. The extension provides a modern open-plan living/kitchen area, improving communal usability — a key requirement in HMO design and licensing.
🛠 Design Highlights:
Rear single-storey extension with bi-folding doors to garden
Ground floor guest room with ensuite and private courtyard
Reconfiguration of internal layout for 10 habitable rooms
Upgraded communal facilities (bathrooms, laundry, storage)
Maximised daylight and space for better tenant wellbeing
Future-proofed design aligned with HMO planning and fire safety regulations
🌍 Location & Planning Context
Located in the heart of Cardiff, this property benefits from strong rental demand. Our team managed the planning application, ensuring all proposed works adhered to local authority HMO policies, space standards, and British Building Regulations.
