Passion for Alchemy


“Alchemy” is the term that encompasses what PQNK strive for: finding architectural potential and keeping our architectural tradition in the continuing evolution. PQNK has garnered acclaims in discovering potential. We are the alchemists who uncover extraordinary results out of ordinary and modest resources; in each journey with our clients, we bring symbiotic relationships to light, resulting synergetic effects.

Seamless Process


PQNK team gives impeccable attention to detail and provides a reliable solution to time and budget constraints. As we think it is important for the clients to avoid unnecessary waste of time, money, and efforts, every project requires smooth, prompt working procedures across the project timeline. This seamless process is PQNK’s one of the integral values, which ultimately relates to our strong belief in the importance of a relationship with the client.



All the key values of PQNK can be epitomized into one word: relationship. As we acknowledge that the alchemy can also be created by good relationship, we work with every project team member with passion and dedication so that we bring the better outcomes to the clients.  Our long-standing clients and strong works demonstrate PQNK’s firmly established relationships.
