What's Included in Premium Plus

Every deliverable from our Premium package, plus structural revisions and two engineer-led site visits — all at one fixed fee.

Full on-site measured survey and detailed architectural drawings tailored to your vision and local planning policy.

Building Regulations Drawings

Full structural and technical drawings to satisfy Building Control — everything your contractor needs to build with confidence.

Client-Focused Building Contract

A Hampshire Build building contract with milestone-based payments in arrears, protecting you throughout the construction phase.

Structural Revisions × 2 — Included

Up to two structural drawing revisions at no extra charge. Each revision typically costs £750+VAT if charged separately — both are included in Premium Plus.

Site Visit 1 — Foundation Stage

Our engineer attends site at excavation stage to inspect depth, width, and condition before concrete is poured. Timed to align with your Approved Inspector's visit.

Site Visit 2 — Steel Stage

Our engineer returns once structural steel is in position to check installation against approved drawings. A second written report is issued within 5 working days.

Two Written Site Reports

A detailed written report follows each site visit within 5 working days. Reports can be presented to mortgage lenders or insurers if required.

Your Two Engineer Site Visits

1

Foundation Stage

Once your foundations are dug, our engineer visits site to inspect the excavation depth, width, and condition before concrete is poured. This visit is timed to align with your Approved Inspector's inspection.

Additional visits beyond the two included are available at £950 + VAT per visit (subject to terms — see clause 8.7 of our Terms & Conditions).

Structural Revisions — Included

Most extension projects require at least one structural revision during the design or building regulations process. In our standard packages this is charged at £750 + VAT per revision. In Premium Plus, two structural revisions are included as standard — giving you up to £1,500 + VAT of revision work at no additional cost, and certainty that your budget won't be affected by design changes.
