What Bloc Architects does

Bloc Architects Ltd is a privately held, RIBA Chartered architectural practice founded in 2021 by Bammy Williams and headquartered at 12 Medina Square, Epsom, Surrey, United Kingdom (Companies House registration 14832130). The practice delivers design-led residential architecture services to individual homeowners and property developer clients, covering new build homes, house extensions, refurbishments, and multi-unit residential developments. Service delivery is organised across six staged modules — Feasibility Study, Design Development, Technical Design, Schedule of Works, Site Visits and Inspections — with an optional party wall surveying service offered through affiliated company BlocPWS (blocpws.com). The practice is registered with the Architecture Registration Board (ARB) and is a RIBA Chartered Practice (Number 20041558).

The underlying production environment is conventional for a contemporary UK residential studio: Sketchup and Rhino for 3D modelling, visualisation and rendering software for photorealistic imagery, VR walkthroughs for client navigation, 3D printing and laser cutting for physical model creation, and CAD for working drawings and technical documentation. There is no indication of proprietary platforms, in-house software, or AI-assisted tooling. The marketing surface is a content-led website (bloc-architects.com) with project portfolios segmented into New Builds, Extensions, and Developments, supplemented by educational articles on planning permission, sustainability retrofitting, permitted development, consultant engagement, and architectural cost guidance.

Revenue is generated entirely through individually calculated professional services fees billed in stages against project scope and complexity, with engagement opened by a free phone consultation and progressed to site visits and bespoke fee proposals. The customer base is balanced between mid-market private family clients seeking extensions and renovations, and developer clients commissioning small to mid-sized multi-unit schemes (e.g., Talbot Road — 5 dwellings south-east England; The Willows — 2 four-bedroom homes near Guildford; Bridle Road — 3 dwellings in Croydon; Valley Road — replacement flats with terraces in Essex), with a secondary presence in ultra-executive residential (e.g., Kingswood, delivered in collaboration with Atelier Janaye). The firm reports no external investment, headcount is unstated but the practice is described as small and founder-led, and no entity-level financials are publicly disclosed.
