KLPOA is a boutique residential architecture practice built on a simple idea: the home you live in should actively make you healthier. Most houses are designed for how they look and what they cost. We design for what you breathe, how you sleep, and how a space feels to live in day after day — without ever compromising on beauty or craft.

The practice is led by Kacper Lastowiecki, a licensed architect (AIA, NCARB) and WELL Accredited Professional with a Master of Architecture from Princeton. That combination is rare: a designer who can draw a genuinely beautiful home and speak fluently to indoor air quality, material chemistry, circadian lighting, and moisture control. Kacper leads every project personally, start to finish — there's no handoff to junior staff, and no project is too detailed to earn his full attention.

We take on only a small number of projects each year, by design. That focus lets us go deep: pressure-testing every material choice, HVAC decision, and window placement against how it will affect the people inside. Whether you're building new, renovating a whole house, or trying to understand why your current home doesn't feel right, KLPOA brings the rare mix of architectural craft and building-health expertise to make your home a place that supports you.
