Singapore's 30 influential spatial / interior designers

We are thrilled to share that our principal architect and founder Ar. / ID1. Tan Yue Wei was recognised as Singapore’s 30 most influential spatial / Interior designer 2025!

Most of us would know that Ar. stands for architect, but how many of us know what ID1. stands for? ID1. is an accreditation by the Singapore Interior Design Accreditation Council.

Here at YWA, we aim to excel at both design disciplines and bring our design expertise to projects of all scale and sizes!

There are currently 3 tiers of Interior Design Accreditation:

ID Class 1 – Interior Designers with Structural and Spatial Expertise

Practitioners in this category are distinguished by their advanced capabilities in both spatial planning and structural design. With a minimum of a university education, these professionals possess the depth of knowledge required to navigate and manage complex design challenges, ensuring that every space is not only visually stunning but also structurally sound.

ID Class 2 – Interior Designers

Class 2 interior designers are equipped with a robust foundation in design principles, gained through a diploma education at local polytechnics and institutions. Their expertise lies in creating interiors that balance functionality with aesthetic appeal, making them well-suited to tackle a diverse range of projects from residential to commercial spaces.

ID Class 3 – Decorators, Stylists, and FF&E Designers

Specialising in the fine details that complete a space, Class 3 professionals focus on decoration, styling, and the selection of furniture, fixtures, and equipment (FF&E). Trained through the Institute of Technical Education, these practitioners excel in bringing design visions to life through careful selection and arrangement, adding the finishing touches that make spaces uniquely personal and inviting.
