Passive House Architect in DC | Contemporary Residential Design

Contemporary Residential Architect in Washington DC

Plan H is a Washington, DC–based residential architecture studio designing contemporary, high-performance homes rooted in clarity, restraint, and long-term comfort. Our work combines Passive House principles with intentional design to create spaces that feel calm, quiet, and deeply supportive of daily life.

Most people don’t remember floor plans—they remember how a home made them feel. Morning light, a sense of ease, a place to gather or retreat. At Plan H, every project begins by understanding how you live, what brings comfort, and what kind of atmosphere your home should hold over time.

While we are based in the Washington, DC region, we work with clients across the U.S. who share our values and are looking for architecture that is both emotionally grounded and technically precise.

Design Values

These principles guide our work as residential architects practicing in Washington, DC and beyond.

Intention
Every architectural decision serves a clear purpose—spatially, technically, and emotionally. Nothing is arbitrary, and nothing is added without reason.

Connection
We design homes that strengthen relationships: between inside and outside, light and material, people and time. Architecture should heighten awareness, not distract from living.

Timelessness
We favor clarity of form, durable materials, and restraint over trend. The goal is architecture that feels relevant decades from now, not dated by its moment.

How we begin a Project

Designing a home begins with clarity—about priorities, constraints, and what truly matters in daily life.

Before moving into full architectural services, Plan H begins with a focused first step designed to align on goals, budget realities, site conditions, and overall direction—so the design work that follows is grounded, confident, and deliberate.

If you’re considering a new home or major renovation and want to explore whether Plan H is the right partner, the options below outline how we typically begin:

FOUNDER — Crafting Contemporary Passive House Architecture

Jean-Michel Humbert, founder of Plan H, Passive House architect in Washington, DC

Jean-Michel Humbert is a Washington, DC architect focused on residential contemporary architecture and Passive House design. Born and educated in France, he brings forward a European sensibility rooted in proportion, clarity, and material character—an approach that continues to shape the calm, intentional spaces created at Plan H.

After practicing in Nancy and Paris, Jean-Michel founded Plan H to explore the intersection of high-performance building science and emotional depth. He believes sustainability is not the goal—it is the baseline. Comfort, health, beauty, and meaning come first.

As a certified Passive House designer, Jean-Michel treats building performance as a creative driver—integrating energy efficiency, comfort, and air quality from the earliest sketches to support architecture that feels quiet, grounded, and deeply human.

Today, he guides clients through a collaborative, values-driven process—helping them make confident decisions and create homes that are not only high-performing, but deeply personal. His role is not simply to design buildings, but to translate priorities, constraints, and aspirations into architecture that feels coherent, durable, and lived-in from day one.
