Our Story
Two creative forces. One shared vision.
SISA was formed through the collaboration of Sash Innovations and Studio Akpan. Two design studios with distinct identities, yet a shared obsession with form, detail and storytelling through space.
What began as intentional collaboration soon revealed a deeper alignment in values and vision. Where one explored form, the other refined function. Where ideas were imagined in sketches, they were realized through material, structure and execution.
In 2025, this synergy evolved into SISA, a dedicated entity created to deliver end-to-end architecture, interior design, construction and project management. SISA does not replace its founding studios; it brings their strengths together under one umbrella to execute projects seamlessly from concept to completion.
At SISA, we design with clarity, build with care and manage every detail with intention. We believe in spaces that feel like a memory waiting to happen; layered, human, and enduring.
Our Why
We exist to make people feel at home — wherever they are.
We believe design is not just about beauty, but about comfort, intuition, and trust.
We obsess over the details most people never notice — because we know it’s those quiet elements that make a space feel right.
From first sketches to final installations, our work is a conversation: between vision and craft, ambition and honesty, aesthetics and need.
We don’t just design spaces. We design experiences of belonging.
