Step-by-Step

 

 

1. Consult and design – meet with a specialist to discuss needs, draft designs and establish a realistic budget.

2. Secure planning permissions – liaise with the local council to approve designs and ensure building regulation compliance.

3. Prepare the site – arrange for any necessary demolition, clear the area and set up temporary structures.

4. Begin construction – execute structural work, install utilities and build out the new space under expert supervision.

5. Complete internal finishes – add insulation, plastering, flooring and final decorative touches.

6. Inspect and obtain sign-off – ensure all work is inspected and meets statutory requirements.

7. Handover the completed space – finalise details and prepare your new extension or conversion for use.

 

 

Completion Checks

 

 

• All structures are sound, with no visible defects or breaches in building regulations.

• Final inspections confirm that electrical, plumbing and structural works meet statutory standards.

• Finishes, insulation, and ventilation are checked to ensure comfort, efficiency and durability.

• Appropriate certifications and sign-offs have been obtained for the entire project.

 

 

When to Call a Pro Instead

 

 

If a project involves major structural changes, complex planning permissions or specialised installations (e.g. integrated smart home systems), then consulting a fully qualified architect, structural engineer or building contractor is essential to ensure both safety and long-term value.
