A 1921 Building Taken Seriously

Historic Building
Commercial Design
Office Remodel
Seattle

The bones are 100 years old. The brief was to make the rest of the building match them.

A building built in 1921 has earned something most interiors never achieve: real character. The wear is real, the proportions are from an era when buildings were designed to last, and the structural honesty is the kind that costs money to replicate when it’s gone. When MarketHQ commissioned this remodel, the instruction was clear: this cannot look like a startup office.

The challenge was modern function within historic form — acoustic privacy for video calls, zone definition for focused and collaborative work, and visual differentiation that lets people navigate without signage. None of that required moving the bones.

Designed Around What Can’t Move

The original structural elements were non-negotiable — they define the building and they were not moving. That constraint became the design framework: everything new was chosen to work with exposed masonry, original windows, and proportions that don’t respond the way new construction does.

Wallpaper became the primary zone-definition tool. In a building where adding walls costs character, wallpaper patterns define areas visually without construction. Each zone reads differently. The transitions are deliberate.

The Challenge

The Challenge: Modern Function in a Historic Shell

Modern workplaces require specific things that 1921 buildings were not designed for: acoustic privacy for video calls, defined zones for focused and collaborative work, enough visual differentiation that people can orient themselves. In a building where you can’t move walls without losing what made the building worth keeping, these are design problems.

The existing palette was original masonry and aging plaster — surfaces that absorb sound unevenly and read as cold under artificial light. The intervention had to solve acoustic and visual problems simultaneously, with materials that could hold against 100-year-old bones without looking placed.

Our Design Approach

How We Solved the Acoustic Problem

Zoom rooms were built into corners where the structural grid allowed enclosure. Acoustic treatment was installed behind finished walls. From outside, the rooms read as part of the original building’s rhythm. Inside, they function fully for video calls.

Carpet insets define the meeting and lounge zones. On a historic building floor, hard surface throughout creates echo and noise that’s uncomfortable for the number of hours people actually spend in an office. Carpet in specific zones solves the acoustic problem and creates visual differentiation that tells people what each area is for — without signage.

Original structural elements were cleaned and detailed, not concealed. The 1921 bones are the design. The new materials were chosen to exist alongside them rather than replace them.

Common Questions

Frequently Asked

Identify what the building has that new construction can’t replicate — structural honesty, proportion, material age — and build everything new around those elements rather than covering them. In this project, every decision defers to what’s original. New wallpaper patterns work with the masonry. Acoustic panels go behind finished surfaces. The bones stay visible.

Because adding walls in a historic building costs you the thing that makes the building worth being in. Wallpaper achieves visual differentiation — each zone reads differently, people can orient themselves — without altering the structure. The building’s proportions and ceiling height remain intact throughout. The result is zone definition that reads as intentional without reading as constructed.

Hard surfaces throughout — masonry, plaster, original hardwood — create echo and noise transfer that a modern building’s acoustic insulation handles passively. Here, the solutions had to be active: acoustic treatment in the Zoom rooms, carpet insets in the meeting and lounge zones, and material choices that absorb rather than reflect. All of it was installed in ways that read as design decisions rather than acoustic mitigation.

By creating a visual and tactile boundary that doesn’t require a physical barrier. A carpet inset in a meeting zone tells people what the area is for before they read it consciously. It also solves the echo problem that hard surface throughout would create. The insets are cut flush with the surrounding floor so the transition reads as deliberate rather than patched.

By using the existing structural grid. In a 1921 building, the column grid and room configurations create natural enclosure opportunities where the structure already provides three sides. We identified corners and alcoves in the existing grid and built Zoom rooms there, adding one finished wall with acoustic treatment behind it. From the outside, they read as part of the original building’s rhythm.

Your home should stop you. Every time you walk in.

The work in this portfolio is the standard we hold ourselves to on every project — not just the celebrated ones. We take on a limited number of engagements each year, which means the projects we commit to receive our full attention from the first conversation through the final installation.

If you're considering a renovation, a new build, or a full redesign, tell us about your home. We'll tell you honestly whether we're the right fit — and what working together would look like.
