SLA

What SLA does

SLA is an internationally renowned nature-based design studio headquartered in Copenhagen, Denmark, founded in 1994 by Stig L. Andersson. The firm operates 130 specialists across twelve disciplines (landscape architecture, biology, anthropology, city planning, forest engineering, lighting design, and computational design) and more than fifteen nationalities, with additional offices in Aarhus and Oslo. SLA designs cities, public spaces, and nature at scales ranging from city-wide masterplans to neighborhood pocket parks, serving government agencies, real estate developers, corporations, healthcare and education institutions, and international development organizations across Europe, North America, Asia, and the Middle East.

The studio's core service offering is interdisciplinary nature-based design integrating landscape architecture with rigorous biological and anthropological research. Its primary proprietary technology is SLIM (SLA Landscaping Information Modelling), a custom-built computational design platform that merges real-time 3D modeling with data-driven feedback on biodiversity impact, irrigation needs, carbon sequestration, plant viability, social programming, and lifecycle cost. SLIM was operationalized through the design of 104 neighborhood parks in Abu Dhabi and represents a differentiated capability within the studio's workflow. Flagship projects include the New Rouge National Urban Park (114 sq km, Ontario), MIND Milan Innovation District (100 ha), Downsview Framework Plan (520 acres, Toronto), Quayside (Toronto), Bjørvika masterplan (Oslo), UN17 Village (Copenhagen), and China Mobile Nature Campus (Nanjing).

SLA operates a project-based professional services revenue model, securing engagements through international design competitions, direct client commissioning, and collaborative multi-firm teams with tier-one partners such as Henning Larsen, Perkins & Will, Lendlease, and Waterfront Toronto. FY2023 revenue was 116.7M DKK (~$15.7M USD) with a 73.3% gross margin, 7.9% net margin, and 47% equity ratio. The firm is privately held by a partner group of three senior partners, ten partners, and seven associate partners, with no external parent or institutional investor.
