Flats, listed buildings and conservation areas always require full planning. Article 4 status here: No. We check eligibility free at the site visit.

Collier Row is characterised by 1930s semi-detached, post-war. The dominant stock is 1930s semi-detached. We've drawn extensions and lofts for every period represented here — Victorian rear additions, Edwardian side returns, 1930s wrap-arounds, and contemporary infill where the streetscape allows.

Havering Council statutory determination is 8 weeks for householder applications. Validation typically adds 1–2 weeks. From your first call to a decision, expect 12–14 weeks total: 1 week measured survey, 2 weeks design, 1–2 weeks validation, 8 weeks determination. We've achieved a 98% first-time approval rate across Havering.
