Architectural design
We offer tailored architectural design solutions for home extensions, conversions, and new builds. Our process begins with initial consultations to understand client needs, followed by creating scaled drawings that comply with planning and building regulations. Clients receive detailed designs that maximise space while ensuring structural integrity and aesthetic harmony with existing properties.
Project management
Our project management service ensures seamless execution of building projects. This includes coordinating qualified tradespeople, conducting weekly site visits, and resolving issues promptly. We manage timelines, quality control, and compliance with local authority approvals, providing clients with peace of mind and a finished project that meets exact specifications.
Home extensions
We specialise in creating functional and visually appealing home extensions, including two-storey additions and family room expansions. Each project is designed to complement existing architecture while enhancing living space. Our services cover planning permissions, structural calculations, and coordination of construction teams to deliver high-quality results.
Loft conversions
Our loft conversion services transform unused attic spaces into practical living areas. We handle all aspects from initial design and building warrant applications to structural modifications and finishing touches. Projects include dormer extensions and roof space conversions, ensuring compliance with safety and insulation standards.
