You're not just finding a room. You're joining a family.
My time at the Castle co-living co-working house in Singapore was truly life-shaping. The environment was one where people were constantly bouncing wild speculative ideas and critiquing each other's world models. It was a rare space where conversations were never dull, and I learned so much from the diverse group of experts who shared their insights and experience.
I particularly want to shout out Kunal, who was always willing to help with anything, and Kan, who was direct and have good knowledge about almost everything. They both taught me so much and were great examples of the curious, ambitious, and collaborative people who make up the community.
From board games to workout sessions, there was always a meaningful group activity to participate in. Moving out was my only regret, and I wish I could stay a bit longer! I highly recommend this space and community to anyone looking to surround themselves with great people in one of the most convenient locations in Singapore.

I shape my life through interesting conversations, so the Castle is in general a pretty life-shaping place for me.
It's pretty great to bounce wild speculative ideas and crazy world models off of the people there and have everyone run with them, critiquing and going further. The Castle's one of those rare environment where all the people can't stand talking about the weather.
Particularly shaping for me are Conrad (who is ridiculously disciplined and rigorous about systematizing decision processes) and Kan (who's so damn direct and problem solving-focused on whatever's in front of him). Assuming you're the kind of person who feels more fed by ideas than food, find a way to meet these people.
CS PhD Student
Having lived in many co-living spaces before, this experience has drastically upgraded my understanding of how communal living should be.
It's more than a place to sleep. It's a place to engage with people who genuinely care about helping each other and having meaningful conversations that drive significant value. It created a strong sense of community and really made it feel like home.
As a digital nomad, I’m always on the move. But no matter where I may go in the world, any time I need a place to live, I know where I'm going - home.
Investor, Advisor and Builder
I joined the community because I wanted to be in the company of intellectual, passionate people who are trying to realize their potential. What I got was so much more. From the moment I stepped in, I felt at home and became part of an amazing family.
There have been very stimulating intellectual conversations (e.g. mental models, growth hacks) and deep emotional and personal experience sharing.
If you are driven, and have a hunger to learn, experience, and grow, you'll fit right in.

The only regret I had moving out of Co-x3 house was “Why didn’t I move in earlier?”
The people who are part of this community are some of the most curious, ambitious, and collaborative people I have met.
I would highly recommend the space and community to anyone looking to surround themselves with great people in one of the most convenient locations in Singapore.
Founder At Give Asia
I've enjoyed tremendous personal growth and learning through deep, meaningful conversations in this house. I love this warm space where I can voice out my daily wars and be supported with timely, actionable insights.
Being a part of the family has helped me to slowly discover my own confidence in areas where I felt lacking. I really appreciate the time and energy everybody puts into supporting each other.
If you're looking for a community to support you through your personal growth, you'll find it here.
Dancer and Choreographer
I've been a part of the Co-x3 Family for months before I knew I had to move across the world to build my startup. It was serendipitous to learn that there was a co-living house where I could stay with growth-minded people and learn faster together.
As a newcomer to Singapore, the connections I've made here have been extremely valuable to make new friends and potential business partners. There's always a special magic in our events that allows people to open up about meaningful topics within hours of meeting each other - I haven't come across anything close.
Founder At Strive Math
Living here has been one of the top highlights of my time working abroad. I came into Singapore with no guidance and support, and I found all of this at the house. With such a wonderful community, it became so much more than just a home.
I’ve had the most engaging and intellectual conversations while simultaneously playing video games, bonding with the other housemates and learned more about myself and my passions through these discussions than I’ve ever had before. I was able to co-work in this space amongst unique and driven individuals and continued to be inspired to challenge myself everyday to meet my self-development goals. If you’re looking for a collaborative and engaging community that exudes warmth, this is the place for you.
Undergraduate At Stanford
My intention to join the community was purely based on my thrive towards honest exchange. I wanted to converse with people who were simply open to share.
In this community, you are not limited to the conversations of every day, but expand to topics as diverse as emotions, life hacks, and the intricacies of creation. I learned to listen more than talk and complementarily think to achieve my goals.
If you are open to sharing about your challenges and tackling them to grow, this is the perfect place to be at.
Engineer At QuantumBlack
I had the pleasure of living with these wonderful individuals when they started The Castle, and really got to experience what co-living could offer. A believer in lifelong learning, I got to explore and participate in many different topics through conversations over dinner, mindful discussions, guest sharing sessions, and workshops.
It is a great environment for folks who enjoy stimulating conversations, meeting people from different backgrounds, or just looking for a fun co-living experience! Words can’t describe how much I enjoyed my time there, but numbers can, 10 / 10.
Software Engineer At OSRF
It's amazing living in a space where you have access to experts who have good fundamentals of their crafts. This helps me learn different topics, discuss, and brainstorm, at tremendous speeds.
It's a fun and engaging learning environment, with plenty of meaningful group activities to participate in - from board games, workout sessions, pool events, and much more.
I highly recommend this place if you want to take advantage of a great self-development hack and increase the slope of your learning curve.
