What Hoehler+alSalmy does

Hoehler+alSalmy (H+S) is a private architecture studio founded in 2009, headquartered in Muscat, Oman, with a global footprint spanning offices in Belgrade (Serbia), Colombo (Sri Lanka), and London (United Kingdom, via the H+S Studio sub-brand launched in 2022). The firm traces its lineage to Hoehler + Partner, established in 1970 in Aachen, Germany; the 2009 partnership with Muhammad Sultan AlSalmy brought the practice into the Sultanate of Oman and seeded its Middle East expansion. H+S describes itself as a global studio for sustainable architecture, urbanism, engineering, and design, with 98 team members worldwide and 115 completed projects across government, hospitality, education, commercial, cultural, and residential typologies. Named projects include the German Embassy in Muscat, Oman Pavilion at Dubai Expo 2020, GUtech campus, Muscat University New Campus, Crowne Plaza refurbishment, Indigo Hotel Yiti, Al Baleed Resort, Capital One Building, and Porsche and Audi showrooms.

The firm operates a full-service, project-based professional services model organized around twelve service modules spanning planning and consultation, design, architecture, interior design, MEP design, construction supervision, sustainability, and design technology. Its technical backbone is the Autodesk suite (AutoCAD, Revit, BIM, DOCS, BUILD) used for design coordination, clash detection, and Digital Twin deliverables, with LEED and BREEAM sustainability expertise integrated from project inception. Revenue is generated through bespoke, quote-based project fees structured as multi-year contracts, with no standardized pricing tiers disclosed. Go-to-market is direct enterprise field sales, led by a dedicated business development function, targeting government ministries, embassies, hotel operators, universities, and commercial developers in the Middle East and select international markets.

Customer concentration is diversified across four primary verticals (government, hospitality, education, and commercial) with no single dominant logo in the named client set. The London-based H+S Studio sub-brand extends the offering into workspace and commercial interior design and operates independently while collaborating with the parent company on joint projects. The firm is privately held with no disclosed external funding, venture capital, or private equity investment; founder and family leadership remains operationally central through Muhammed al Salmy as Group Managing Director.
