What POULSOM MIDDLEHURST LTD does

Poulsom Middlehurst is a South London-based residential architecture studio founded in 2011 by architects Amy Poulsom and Jane Middlehurst. The practice delivers design services for residential projects across Greater London, including home extensions (loft, rear, and side), spatial reconfigurations, whole-house refurbishments, and custom-build new homes. Its positioning centres on an accessible, collaborative design approach that demystifies the construction process for homeowners working within defined budgets.

The practice operates a two-surface offering. The primary line is project-based architectural professional services, with fees quoted per engagement and projects typically spanning multiple years from concept to completion. The secondary line is HomeNotes, launched in 2021, an online platform and mobile app that provides visual budgeting and project-planning tools for budget-conscious renovators. HomeNotes is positioned as a content and tooling complement to the architecture practice rather than a standalone monetised software product.

Commercially, the firm is privately held by its two co-founders with no external institutional investment and no parent company. It acquires clients through direct enquiries, referrals, press coverage, and the content-marketing flywheel generated by the 'Stories from Site' podcast (Best Podcast, Archiboo Awards 2024) and the HomeNotes platform. The practice has accumulated industry recognition including a RIBA London Award 2025 for the Blenheim Grove custom-build project and a RIBA Guerilla Tactics Live Pitch win in 2015. Customer concentration is structurally low: every named engagement is an individual homeowner or small household, and revenue is not disclosed.
