Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers

“In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.”
Significant events
- “A key strategic development during the year was increased investment in design and research capability, reinforcing the Company's position as a leader in innovation, bespoke architecture, and high-specification construction.”
- “The Company successfully delivered eight major projects during the year, with high client satisfaction levels, minimal project overruns and continued focus on quality assurance and design excellence.”
