Design and Build Services for Extensions and Barn Conversions
Below are a few key points that reflect our design and build approach and why this is the ideal method for extensions and barn conversions.

Why Hiring a Design and Build Specialist Makes All the Difference
This is exactly what Extension Architecture brings to the table. As a design and build specialist, Extension Architecture offers a streamlined and cohesive approach to delivering complex, customised projects, especially when it comes to extensions and conversions.
- Single Entity: Sole ownership means complete ownership that accounts for complete responsibility of both the design and the construction. This ensures clear communication and full accountability during the project.
- Eliminates Risks: With a single communication channel, risks are often eliminated with less scope for any miscommunication or misinterpretation, which is extremely vital in technically challenging projects like barn conversions or major extensions.
- Timely Completion: The design and build team works in collaboration, planning, design development, procurement, and site preparation can be tightly scheduled. This helps the project progress more swiftly and efficiently.
- Reduced Stress: With one unit managing planning permission and structural calculations to final output, the process becomes simpler and transparent. This unburdens the numerous worries and anxious moments for the client, resulting in a less stressful endeavour as any disputes or issues too will be taken care of by the entity themselves.
Our Step-by-Step Process: What to Expect When Working with a Specialist Team
Barn conversions, on the other hand, offer a rare opportunity to turn character-filled structures into modern homes suitable for urban living.
The commonality is, both of these require careful planning, structural expertise, and creative vision, which can only be realised with the intervention of specialists.
Below is a step-by-step process of what you can expect when working with a specialist team like Extension Architecture –
1. Consultation and Feasibility Assessment
- Assessing site condition and structural feasibility
- Taking planning considerations into account (specific to the location or borough).
2. Conception and Planning
- Layout proposals and 3D visualisations
- Integration with the existing structure or original features (particularly important for barn conversions)
- A clear planning strategy that aligns with local authority guidelines.
3. Technical Design and Structural Engineering
- Structural calculations by our structural engineers
- Coordination of essential services like drainage, insulation, including installation of mechanical systems
- Specification of materials and finishes
- For barn conversions, this step is critical to ensure the structure is safe, efficient, and in harmony with its original character.
4. Construction and Project Management
