E2 Architecture

What E2 Architecture does

E2 Architecture is a London-based specialist conservation architecture practice founded in 2007 by Sam Cooper. The firm delivers contemporary conservation architecture across listed building work, new build homes, residential and commercial development, contemporary interventions, deep retrofit, and integrated interior design, serving three primary customer segments: private homeowners undertaking heritage home projects, developers and investors pursuing planning gain on constrained sites, and heritage institutions such as Morden College. Differentiated capability centers on RIBA Conservation Architect accreditation (held by Sam Cooper, one of approximately 250 in the UK), deep retrofit expertise under PAS2038 (EPC E-to-B at The Old Drill Hall), and a track record of unlocking planning consent on complex heritage sites where other practices have failed.

The practice operates a project-based professional services model with bespoke, fixed fees rather than percentage-of-build pricing. Entry points include a free initial appraisal and a paid Architect Home Visit consultation priced from £2,200 + VAT, with full project fees scaling into the low-to-mid six figures based on visible budget tiers (up to £2M+) on the website contact form. Lead generation is sales-led via direct consultation, website enquiries, and content marketing through the 'E2 Elevation' newsletter, blog content, Instagram, earned media, and Google reviews; the firm also participates in industry events such as Grand Designs Live. Geographic scope is regional, covering London and the South East of England.

E2 is structured as E2 Architecture and Interiors Ltd, a private limited company registered in England with no external investment, no parent company, and no M&A activity disclosed. The team comprises founder-Director Sam Cooper plus three named professionals (Elizabeth Sonubi, David Obaro, Associate Jim), with a partnership with Cooper & Cooper Interiors providing integrated interiors capability. The practice has been recognized through awards including the Sunday Times British Home Awards 2017 and Evening Standard Eco+Living Award 2015 for its zero-carbon Pavilion project, and operates from ContainerVille in the E2 postcode of East London since 2019.

• Levitate Architects: Small London architecture practice working on residential, heritage, and developer-led projects including extensions and conversions. Comparable to E2 in scale, geography, and private/developer client mix.
• Purcell: One of the UK's leading architectural practices focused on heritage, conservation, and design of historic buildings. Directly comparable to E2 in serving listed-building clients with conservation-accredited architects and navigating complex planning and listed-building consent.
• Studio Indigo: London-based practice with strong heritage residential work, including Grade-listed renovations, alongside contemporary and interior design. Comparable to E2 in serving high-end private clients on listed and conservation-area homes.
• Feilden+Mawson: UK practice with a strong heritage and conservation architecture arm alongside broader design work. Comparable to E2 in delivering listed-building projects, conservation area work, and contemporary interventions on historic fabric.
• Donald Insall Associates: Long-established UK conservation and heritage architecture practice specialising in listed buildings, heritage planning, and retrofit. Closely comparable to E2 in specialism, client mix (private and institutional), and RIBA conservation credentials.
• Matthew Lloyd Architects: Conservation-accredited UK architect working on listed buildings, heritage retrofits, and contextually contemporary work. Similar in scale, specialism, and client mix to E2, with comparable expertise in planning and listed-building consent.

Broad incumbents

• Stanton Williams: Established London practice with significant work on heritage, cultural, and residential projects. Comparable in heritage and conservation capability but operating at a larger scale and broader portfolio than E2's specialist focus.
• Allies and Morrison: Larger London practice with a broad portfolio across residential, commercial, and heritage. Overlaps with E2 on listed-building and conservation work but as one capability within a much wider practice, making it a broad incumbent rather than a direct niche competitor.
