SERVICES

Our work begins with understanding how you and live and what you already own, focusing on reimagining and repurposing existing furniture, materials, and architectural elements whenever possible. 

The result is a space that feels refreshed, cohesive, and personal - shaped by what you already have and 
love - and thoughtfully built to support how you live.

Design-build Planning & Project Scope

This phase focuses on defining the scope of the work before decisions feel overwhelming. Services may include space planning, layout, drafting plans, and helping determine what stays, what shifts, and what truly needs to change. 

Furniture, Finish, & Fixture Selection

When new pieces or materials are needed, we guide you through thoughtful selections that integrate seamlessly. This includes furniture, lighting, finishes, hardware, and fixtures chosen for beauty and function.

Repurpose & Reimagine Existing Pieces

What you already have matters. A core part of our process is determining how it can be reused, refinished, relocated, or reimagined to create spaces that feel more layered and personal. It's your house, elevated.

Custom Build Work & Hands-On Approach

For projects that require physical changes, I provide hands-on construction services such as custom built-ins, millwork, furniture refinishing, paintings, sculpture, and other tailored solutions.

Our People

See What Our Clients Say about Us

"I’ve had the pleasure of working with Katie on my home and office. She coordinated with my contractor, painted original artwork that reflects my style, and made sure everything looked cohesive in my space. Her talent for repurposing is truly what sets her apart. She didn't come in and suggest I begin again. She curated a thoughtful space from what I had, and I was blown away."

- Stephanie W

—Meg and Jason K

"What I loved most is that you didn't suggest I toss everything or buy all new. You appreciated my family heirlooms and helped me rediscover the beauty in what I already had simply by adding your touch. I cannot thank you enough for creating a space that is unique and meaningful for our family!"

—Abby M
