Source-derived summary

No. 1 Croydon (formerly the NLA Tower, and colloquially the 50p Building, the Weddingcake or the Threepenny bit building) is a tall building at 12–16 Addiscombe Road, Croydon, Greater London, next to East Croydon station. It was designed by Richard Seifert & Partners and completed in 1970. It has 24 storeys and is 269 feet (82 m) high. NLA stood for Noble Lowndes Annuities, the original principal tenant (subsequently taken over by the Hill Samuel Group). It was one of many new buildings constructed in the growing town of Croydon in the 1960s. The development of tall buildings was later encouraged in the 2004 London Plan, which led to the erection of new skyscrapers as Greater London went through a high-rise boom.

Construction

The building was erected between 1968 and 1970. Its distinctive appearance arises from its octagonal floor plans (not, in fact, regular octagons, but squares with splayed or truncated corners), set above one another on alternating orientations.

Construction was delayed by the objections of Miss Kathleen Harding, a solicitor and leasehold tenant of the Victorian East Bridge House, which stood on part of the intended site.

Editorial summary

This brief starts where responsible research should: with the source description of “No. 1 Croydon” as office block in Croydon, south London. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1970, 2004, 1968—that can be checked directly. The linked authority record independently contributes the date 1970. The account is most persuasive where Croydon, office and block can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as office block in Croydon, south London. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 17, 2026. The linked authority identifier is Q7043088. Authority coordinates are 51.375, -0.091. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1970, 2004 and 1968.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
