Personal, Thoughtfully Designed Homes that Enhance Health and Wellbeing

Kacper Lastowiecki, AIA, designs custom homes, renovations, and additions with a focus on wellness, performance, and long-term livability in Washington, DC and throughout the greater DMV

A Personal Approach to Residential Design

Designing or renovating a home is a major investment; financially, personally, and emotionally. My practice was founded to offer a more considered alternative to generic, one-size-fits-all residential design. My Practice offers wellness expertise, personal attention and timeless design for discerning clients across Washington DC, Northern Virginia, and Maryland.

“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.

-J.M. Previous Renovation Client

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.

Schedule a Complimentary Consultation

What to Expect

We accept a limited number of projects each year to ensure personal attention and quality. If you’re considering a high-quality new build, renovation or addition, in the greater DMV region I’d be happy to learn more about your project.

The initial consultation is an opportunity to discuss your goals, scope, timeline, and priorities. We’ll determine whether the project is a good mutual fit and outline potential next steps.

If you’re planning a new build, renovation, or addition in Washington, DC, Northern Virginia, or Maryland, this free consultation is a low-stress, no obligation, first step toward a home that truly supports how you live.

Wellness Focus

Timeless Design

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

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.

Human-Based

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.
