Our Process

We make building extensions and loft conversions as straightforward as possible. Here's how we work:

1

Initial Consultation & Site Survey

We visit your property for a free consultation to discuss your ideas, measure up, and assess any technical considerations. We'll talk through design options, planning requirements, and approximate costs.

2

Design & Planning

We prepare detailed drawings and specifications. If planning permission is required, we can handle the application process on your behalf. We also arrange structural calculations and building regulation submissions.

3

Detailed Quote & Agreement

You'll receive a comprehensive, itemised quote showing exactly what's included. Once you're happy, we agree on a start date and schedule of works.

4

Construction Phase

Our experienced team carries out the build, keeping you informed every step of the way. We manage all trades, maintain site safety, and minimise disruption to your daily life.

5

Completion & Handover

We complete all finishing touches, arrange final inspections, and hand over your new space. You'll also receive guarantees and aftercare information.
