Our Practice
We are a husband and wife led multidisciplinary agency founded in 2020 with complementary backgrounds in architecture, urban design and real estate finance. Our combined experience in teaching and building creates a unique dialogue within the practice which makes our approach to design both academic and hands-on. As firm believers of social equality, we are a proud woman co-founded company dedicated to inclusivity and diversity in architecture, design and the building industry at large.
