Each instruction produces a stamped calculation pack tailored to your property — not a copy-paste template. Specifically:
| Package | Scope | From | Turnaround |
|---|---|---|---|
| Single-floor removal | Gallows brackets onto party wall, no beam required | £300 | 5 days |
| Full stack support | Steel beam carrying the remaining stack above — heavier loads or no party-wall bracket option | £450 | 7 days |
| Multi-floor partial | Breast removed on two floors, stack retained above — combined bracket + beam design | £600 | 7–10 days |
How do I instruct you?
Email or call with photos of the breast on each floor plus a sketch. We quote inside one working day. 50% deposit on instruction, 50% on issue of the pack.
Will you handle the Party Wall notice?
We don't act as Party Wall surveyor, but we provide every drawing and calculation your appointed surveyor needs. We can recommend surveyors we've worked with locally.
Can the design be revised if my builder prefers a different method?
Yes — one revision included free. Further revisions are quoted at a small flat fee, never hourly.
Do you visit site before designing?
Ground-floor-only on a standard terrace — photos are fine. Multi-floor, partial removals or older flank walls — we visit, typically inside two working days in Ilford and Thurrock.
Will Building Control accept your calculations?
Yes — we submit regularly under Redbridge, Newham, Havering and Thurrock Building Control. If they query anything we deal with them directly.
