About the Practice
A Personal Approach to Residential Architecture
Designing or renovating a home is a major investment; financially, emotionally, and personally. My practice was founded to offer a more considered alternative to generic, one-size-fits-all residential design. Learn more here.
Wellness-Expertise
As a WELL Accredited Professional, and Licensed Architect I design homes that actively support health and wellbeing; from cleaner indoor air and better daylighting; to holistic material choices that feel good to live with every day. The goal is not just a beautiful home, but one that supports your lifestyle and genuinely helps you flourish.
Timeless Design Quality & Smooth Design Process
My practice is small by design. I personally lead every project, working directly with you through design, documentation, and construction. There are no handoffs or junior staff; just clear communication and guidance throughout.
We also categorically reject the use of Artificial Intelligence in design and client communication. Your unique, one-of-a-kind design will result from an active collaboration between client and architect, not from an algorithm that spits out slop.
When you communicate with the Practice, your communication will always be read and responded to by a human being.
Good architecture is about more than trends or surface finishes. Each project is approached with architectural rigor and attention to detail, resulting in homes that feel serene, intentional, and timeless; spaces that age gracefully rather than date quickly.
Excellence in outcome comes from excellence in process, that’s why providing a smooth and calibrated design process is key to the way we work. We aim to be transparent and set clear expectations so you are always in-control of the final result and always have a clear understanding of what to expect.

Personal Attention, From Beginning to End
Testimonials
“We had an old fixer-upper with truly odd quirks. Kacper helped us create our dream home. The process was amazingly smooth working with him. You know what it will cost, what each step entails, and what you will receive. He’s really well versed in sustainable and healthy options as well as efficiency concerns. Perhaps more importantly, he’s creative! He listened to our priorities, asked a lot of questions about our lifestyle, and developed a set of options that turned into our lovely home. Highly recommend.”
“We’ve been living in one of Kacper’s homes for a while now, and it’s truly such a special space. The natural light, thoughtful layout, and beautiful finishes make it feel both modern and welcoming. You can tell how much care and craftsmanship went into every detail. It’s such a comfortable, happy place to come home to — we’re really grateful for the quality and design that Kacper put into it.”
“We’ve been living in one of Kacper’s homes that he designed and built for the last year and a half, and it’s clear from day one that this place was created with real intention. The layout actually feels almost ergonomic—every space is purposeful, the flow makes sense, and natural light moves through the rooms beautifully.”
