What We Do
Design expertise,
end to end.
extnd brings together architectural design, interior design, structural engineering and mechanical engineering under one roof — giving every project a single, coordinated team from first sketch to finished home.
Architectural
We design spaces that are thoughtfully considered, technically sound and tailored to how people actually live. From rear extensions that open the home to the garden, to loft conversions that create light-filled retreats — our architectural work begins with understanding your brief and ends with a design that feels exactly right.
- Home Extensions
- Loft Conversions
- Planning Applications
- Permitted Development Advice
- Party Wall Matters
- Building Regulations
Interior Design
A well-designed interior shapes how a space feels as much as how it looks. We work with homeowners to develop layouts, material palettes and lighting concepts that make every room feel considered, calm and cohesive — whether as part of a larger project or as a standalone interior brief.
- Space Planning & Layout Design
- Material & Finish Selection
- Lighting Layouts & Concepts
- Furniture & Spatial Arrangement
- Custom Joinery & Built-in Design
- Interior Guidance for Renovation Projects
Structural Engineering
Every architectural idea depends on a structure that performs reliably over time. Our structural engineering input ensures that new openings, extensions and altered layouts are designed and built to the highest standard — coordinated closely with the architectural design so solutions are efficient, integrated and code-compliant.
- Structural Calculations & Reports
- Beam & Column Design
- Loft Conversion Structural Design
- Load-Bearing Wall Alterations
- Foundation Design & Assessments
- Structural Guidance for Renovations
Mechanical Engineering
The systems inside a building determine how comfortable it feels day to day. We coordinate heating, ventilation and energy strategies alongside the architectural layout so services are integrated from the outset — reducing disruption, improving efficiency and ensuring the home performs exactly as designed.
- Heating System Design
- Mechanical Ventilation & MVHR
- Hot Water System Planning
- Energy Efficiency Strategies
- Part L Compliance
- Building Services Coordination
