One & Two-Storey Extensions

At Rosenkelly Architectural Design, we specialize in one and two-storey extensions, helping homeowners maximize space, improve functionality, and enhance property value. Our structured approach follows the RIBA Plan of Work, ensuring clarity and efficiency at every stage.

​

Our Process:

1. Initial Meeting & Project Brief (RIBA Stages 0 & 1 – Strategic Definition & Preparation)

We start with an initial consultation to understand your vision, budget, and key requirements. During this stage, we:

✔ Assess feasibility – considering site constraints and planning policies.
✔ Discuss your options – including layouts, materials, and potential challenges.
✔ Establish a project brief – outlining your goals and expectations.

2. Feasibility Study / Concept Design / Pre-Application (RIBA Stage 2 – Concept Design)

• We explore various design concepts based on your brief, ensuring they align with local planning policies.

• If needed, we conduct a pre-application enquiry to gain early feedback from the planning authority, helping to streamline approvals.

3. Planning Application (RIBA Stage 3 – Spatial Coordination)

• We refine the preferred design, preparing all necessary drawings and documents for submission.

• We handle the application process and liaise with the planning authority to maximize approval success.

4. Building Regulations (RIBA Stage 4 – Technical Design)

• Following planning approval, we create detailed technical drawings to meet building regulations.

• We submit these to building control or an approved inspector, ensuring compliance and addressing any technical queries.

5. Construction Management (RIBA Stage 5 – Manufacturing & Construction)

• We assist with contractor selection and oversee the tendering process if needed.

• Throughout construction, we provide contract administration, conduct site visits, and ensure the project stays on track.
