Our Story

We design highly-crafted, site-sensitive homes that reflect the identity, lifestyle and aspirations of our clients.

Since its founding as a boutique architectural design firm by Principal Architect Clement Koh in 2017 out of a Calling from God to specialise in residential landed homes design, Mark 12 has become known for creating well-crafted, bespoke contemporary homes with attentive & personalised services.

We aspire to design works which are thoughtful, unique & timeless. Our team adopt a unique systematic & rigorous approach to both aspects of design and project management. This ensures the building process is organised and methodical for our clients.

For the uninitiated, the process of designing and constructing a dream home can be a daunting & challenging exercise, fraught with potential pitfalls. Our team at Mark 12 are here to assist our clients to navigate this process and achieve their dream homes successfully.

In our first four years, the firm has been blessed to successfully complete more than 12 beautiful homes with many positive testimonials from our clients.
