KSR Architects & Interior Designers

What KSR Architects & Interior Designers does

KSR Architects & Interior Designers is a London-based, partner-led architecture and interior design practice founded in 1983 (originally as Koski Solomon), headquartered in a three-story Camden studio with a team of over 30 people. The firm provides integrated design services across luxury private homes, multi-residential developments, heritage and listed buildings, beachfront schemes, contemporary commissions, and masterplanning, serving high-net-worth private homeowners, residential developers, and commercial/mixed-use developers. Core products comprise Architecture Services, Interior Design Services, an FF&E (Furniture, Fixtures & Equipment) procurement and installation module, and a Regeneration & Placemaking service line targeting strategic urban-development work.

The business model is professional-services project delivery, primarily fee-based and quote-based rather than fixed pricing. Go-to-market is enterprise field sales through direct, partner-led client relationships, referrals, a curated vendor ecosystem (e.g., MY Construction, SMC Smart Homes, dp9, Price & Myers, Heritage Collective, and the strategic Parapluie art-advisory partnership), industry awards, and thought-leadership channels including Instagram, LinkedIn, and the firm's own Journal, plus attendance at MIPIM. The firm operates from a single London studio while delivering projects across the UK, the Caribbean (Antigua, Barbados), South Africa, Monaco, Hungary, Ireland, and historically Moscow, with no disclosed subsidiaries, external investment, or public listing. Revenue, pricing tiers, and contract values are not publicly disclosed.

Direct peers

• Squire & Partners: London-based architecture and interior design practice with deep luxury residential work in prime postcodes, integrated interiors, and a comparable super-prime client base. Closest direct competitor to KSR's integrated architecture + interiors model at a similar boutique scale.
• SimpsonHaugh: London architecture and interiors firm with a high-profile residential and mixed-use portfolio including many trophy towers and luxury homes. Comparable in prime London residential delivery and integrated interiors offering.
• Make Architects: London-headquartered architecture practice with a strong residential and mixed-use portfolio and integrated interior design capability. Comparable in London-centric delivery and HNW / developer client mix, though somewhat larger and more diversified.
• PDP London Architects: London-based residential architecture practice with deep super-prime and prime central London track record across private homes, apartments and developer-led schemes. Direct competitor in KSR's niche of trophy London residences and conservation-area work.
• John McAslan + Partners: London-headquartered architecture practice with significant residential and mixed-use work alongside heritage and conservation projects. Comparable conservation-area expertise and integrated interiors capability to KSR.
• Stiff + Trevillion: London architecture practice recognized for high-quality residential and mixed-use schemes in central London, with an integrated interiors ethos. Closely comparable boutique size, London conservation-area exposure, and developer / HNW client mix.

Broad incumbents

Comparable on luxury residential execution and brand prestige rather than boutique service model.
• Zaha Hadid Architects: Global architecture firm with a London base that competes for high-profile residential and mixed-use commissions. Comparable on luxury design brand and trophy-project delivery, but at significantly larger scale and broader typology mix than KSR.
