Wimshurst Pelleriti

What Wimshurst Pelleriti does

Wimshurst Pelleriti is a London-based RIBA Chartered architectural practice operating as a vertically integrated design studio, developer, and contractor. Founded in 2013 as Wimshurst Partners by brothers Tom and Will Wimshurst and rebranded in 2015 when Leo Pelleriti (formerly of RSHP) joined as co-founder, the firm employs 11–50 people (12 listed on the About page) across its Putney Common headquarters. The practice operates two complementary arms: a core architectural design service covering multi-unit residential, private residential, commercial, leisure, education, heritage, and retrofit projects, and WP Developments, an in-house developer-contractor arm that acquires sites, secures planning, constructs, and sells properties. Revenue is generated through project-based architectural fees (typically a percentage of construction cost or fixed fee per phase), property sales through WP Developments (for example, the nine off-plan flats at Ellison Road), and construction margin where the firm acts as main contractor.

Underlying technology and process capability rests on BIM Level 2 protocols for 3D coordination, ISO 9001:2015 quality management, and voluntary adoption of the RIBA 2030 Climate Challenge and LETI retrofit standards. The firm has secured planning on technically demanding sites — including a 14-storey residential tower in Wandsworth and conservation-area social housing in Teddington — and has won the New London Awards 2021 People's Choice (Hampton Pool), Wood Awards 2024 Sustainability Highly Commended (Liberty Woodland School), and multiple AJ, RIBA, and British Homes Awards shortlistings. Customer segments span residential and commercial property developers (Mizen Design & Build, Solum, Medina Capital, Antonville Investments), housing associations and providers (RHP Group, Richmond Housing Partnership), community trusts and charities (Hampton Pool Trust, Veterans Aid, Hornsey Parish Church), and private individuals. The go-to-market motion is reputation- and referral-led, supported by architectural press coverage, award recognition, and an active project-portfolio website; pricing is project-specific and not publicly disclosed, with individual project budgets ranging from under £100k (Span House) to £50m (Capital Gate).
