About Us

Our Story

YWA primarily started off as an Architectural studio. In the process of offering consultancy services, we realised that the skillset, expertise and experience in project as well as contract management allowed us to provide a more professional approach to clients who reached out to us for interior design services.

With one satisfied customer after another, YWA Interior was established as a standalone team offering the same excellence in design and service. Operating in a multi-disciplinary office retains our ability to provide a holistic approach to more complex projects that require a multi-disciplinary team.

Core Values


YWA places professionalism at the forefront of how we operate and function. This is equally important regardless of whether our Client is an individual or a corporate body. Delivering consistent service to all our valued clients.

Finesse In

We believe that good design translate through from macro to micro. Details are what sets apart the good from the excellent. Details not only refer to our art of design, it is far reaching and it encompasses a state of mind. The state of mind has to be inquisitive, imaginative and thoughtful.


We focus on evolution to build upon our design philosophy. Delivering constant growth throughout our professional journey. Constantly evolving, constantly improving. Honing this core philosophy, we apply our evolutionary approach to revolutionary designs.


1. Do you take on any project and size?

Our team is equipped with the skills and experience to handle a wide range of project scale and size. To ensure and uphold the quality of works and professionalism dedicated to each client, we only take on a limited number of projects a year, thus we are not limited by the scale or size. However, we are selective on the projects we embark on.

2. You seem to have a wide range of design style and are quite unique. Do you have a primary design style?

We do not. We focus primarily on design philosophy; therefore, we are not tied down by design styles. We amplify uniqueness in individuality, crafting bespoke journey through storytelling. Each project is different, while the only one constant is the quality of work we deliver.

3. How do we get started?

Working relationships are very important to us. We always believe that in-person meeting is key to a good kick-off. It allows us to not only capture the brief but also interpret and translate the energy and passion of our clients. It is good to prepare a list of requirements, wants and needs, floor plan, target completion date and a target budgetary provision.

4. Who will we be expecting to handle the projects?

Our team consists of only skilled and experienced individuals who are specialised in this field. Being a part of a multi-disciplinary office, the team is exposed to different relevant fields of knowledge. Every individual handling your project will be a well-trained and qualified designer and project manager.

5. Who will select YWA Interior? Who will not?

Clients who are looking for a professional team that will take them through a well-planned and organised project journey, appreciate good design and quality of works, as well as understand the dedication the team will put into achieving the final outcome, will appreciate us.

As we do not wish to compromise the calibre of work throughout every aspect of our professional engagement, from inception to completion, clients who are looking for extremely competitive contract sums without relevance to the quality, time and effort, may not find us attractive.

6. What is the most common mistake when selecting an Interior Design firm?

Not choosing us.

Multi Disciplinary Vision

While YWA Interior specialises in Interior Design, Consultancy and Project Management, we are also able to work as partners in excellence with our affiliated professional allied consultants in our multi-disciplinary office to provide a holistic one stop approach to all projects.
