PLSAB

What PLSAB does

PLSAB (legal name Pille Lausmäe SAB, DBA Pille Lausmäe Interior Architects) is a Tallinn-headquartered interior architecture studio that has been continuously operating since at least 1993. The firm delivers three core service lines: Residential Interiors (private homes, villas, apartments and historic-property renovations across Estonia and Italy), Public Interiors (banks, museums, schools, courts, embassies and cultural venues, including the ERM Estonian National Museum, the Estonian Embassy in Ottawa, and the Harju County Court), and Cruiser Interiors (specialized design for ferries and cruise ships, including the Viking Line Silja Europa showbar and the M/S Isabelle restaurant/bistro). Heritage Restoration is treated as a cross-cutting specialization, most visibly demonstrated by the 2024 House of the Estonian Knighthood project.

The studio is founder-led: Pille Lausmäe-Lõoke serves as Interior Architect/CEO at certified expert level 8, and is supported by Gerly Vaikre (certified level 7), giving the firm a two-architect FTE base. Work is delivered via direct professional services engagement, with quote-based project fees that are not publicly disclosed. Marketing is portfolio-driven through the firm's website and professional referrals within the Estonian architecture community, and the firm has accepted selective collaborations (e.g., Salto Architects on Villa In Pirita, 2018).

The studio has received multiple national awards from the Estonian Association of Interior Architects (1993, 2008, 2014, 2016, 2024) and the Cultural Endowment of Estonia Architecture Endowment (1998, 2001, 2013, 2015, 2024, 2025), plus a National Heritage Conservation Award and an Estonian State Cultural Award. PLSAB is privately held, founder-controlled, with no external funding, subsidiaries, or M&A activity recorded.
