What ARCHITECTURALL LTD does

ARCHITECTURALL LTD is a London-based private limited company founded in 2010 by Simon Skeffington, a RIBA-registered architect, and Julian Cotet, a construction manager with 18 years of on-site experience and a Construction Management degree. The firm operates a dual-role design-and-build model, functioning simultaneously as an architectural design practice and main contractor for high-end residential projects. Headquartered at 7 Windsor Drive, Chelsfield (Kent), with a team of six employees, the practice serves affluent property owners across South East England — specifically South East London, Kent, Surrey, and East and West Sussex.

The core offering is an integrated architect-plus-contractor service delivered as a single point of contact under JCT Design and Build Contract DB 2016, removing the traditional client-side friction between designer and builder. Project sizes range from 85m² refurbishments to 1,000m²+ new builds, with the typical threshold at 280m². Pricing comprises a free half-day initial feasibility consultancy, design fees of £65 per hour during the 6-8 month concept and planning stage, and construction costs of £2,750-£3,250 per m² for a 10-12 month on-site build. Optional home builder warranties through NHBC or Zurich add approximately 1% of build cost. The firm is member-affiliated with RIBA, ARB, and the Federation of Master Builders.

Architecturall's portfolio emphasises contemporary design inspired by Danish interiors and execution on challenging sites including Greenbelt land, conservation areas, and rural settings. Notable projects include the 650m² Woods Quay Thames pavilion for Wood's Silver Fleet (winner of the Federation of Master Builders 2021 award and featured in Monocle Magazine), the 525m² Speldhurst contemporary house (Channel 4 'This Way Up' filming location, 2021), the 485m² Chislehurst contemporary house, the 350m² Penshurst flint-and-oak rural dwelling in an Area of Outstanding Natural Beauty, and the 175m² Larch House in Guildford. Press coverage spans the Sunday Times, Sunday Telegraph, Grand Designs Magazine, Real Homes Magazine, and Monocle Magazine.
