Morrow + Lorraine

What Morrow + Lorraine does

Morrow + Lorraine is an independent London-based architectural practice founded in 2009 by Julian Morrow, operating as Morrow + Lorraine Ltd. with a secondary studio in Edinburgh. The practice specializes in commercial retrofit, heritage transformation, and sustainable repositioning of buildings for institutional landlords, property estates, and global real estate investors. Core service lines encompass full architectural design across concept, planning, design development, and construction administration, supported by specialist consulting in embodied carbon assessment (using IMPACT-compliant OneClickLCA), circularity analysis aligned with the London Plan, Passivhaus and Enerphit design (via PHPP modeling), and RIBA Stage 7 post-occupancy evaluation. The firm employs both Passivhaus- and WELL-certified architects, holds ISO 14001:2015 certification, and participates in Architects Declare, the Passivhaus Trust, the SteelZero initiative, and the RIBA 2030 Climate Challenge.

Revenue is generated through project-based professional services fees, with individual project values ranging from approximately £600,000 (Heath House) to £40 million GDV (The Baytree, Brentwood) and a portfolio spanning 40+ completed projects across office, residential, retail, and leisure sectors. Customer concentration is heavily weighted toward tier-1 UK estates (Howard de Walden, Crown Estate, Duchy of Lancaster, Church Commissioners) and institutional/global capital (AXA, DWS, Invesco, Gaw Capital, Barings, Legal & General, Berkeley, Grosvenor, Shaftesbury). Go-to-market is relationship-driven via direct client engagement, professional networks, and a credentialed portfolio reinforced by industry awards (AJ Retrofit Awards, OAS Awards, BCO Awards, RIBA, BREEAM, Brick Awards).

The practice has approximately 20 staff organized into directors, associates, architects, interior designers, architectural technologists, and studio/practice management. The firm carries no external institutional investment, no parent company, and no subsidiaries; it operates as a privately held partnership-style entity. Distribution is purely direct — there is no API, no software product, no channel partners — and marketing relies on a project portfolio website, organic social (LinkedIn, Instagram, Twitter), a journal/blog, and earned media through awards and sustainability community participation.
