Pedal Power

Currently in the works as community outreach: AGATHOM is volunteering our services for the Waterfront Montessori Children’s Centre. The school has taken initiative to reduce their carbon footprint by replacing the gas-powered school bus with Dutch bike-buses. With the help of AGATHOM a pre-fabricated bicycle shed is under construction on Toronto’s Wards Island.


Custom-designed wool rugs

Among other textiles, Katja designs rugs for clients to suit their specific projects. Every aspect of the yarn selection, colour, pattern and detailing is considered. She brings a lifetime of wool fabric design and technical knowledge to each unique piece. The high-quality rugs are hand woven in India by master weavers, and shipped to our Toronto studio.

Starting an interesting project? It always begins with a conversation. Why not set up a visit with us? Reach us here.

Company Motor

The AGATHOM truck is here, it’s tuned and ready for its painted graphics. We are looking for the right painter.

First Fire

Inauguration of the wood fireplace at WASAGATHOM, an exciting moment – and it happened on the first snowfall.

AGATHOM retreat

The water was too rough to tie up to Red Rock so we had our dessert on the way home. Welcome new team members: Michael Yoshimura and Joshua Henk seen here with Katja.

Construction frenzy

Steel-toed boots are off and on each week as we visit projects in the midst of construction. This is the rewarding part — seeing ideas come to life. We will keep posting views of the always fascinating process of building-making.

Hard at work

What’s close…? a lot to tune into this spring. New projects are going into the ground all over the land this coming year – stay near.

About Us

Established in 2005, AGATHOM is an award-wining architectural studio and workshop. Located in a landmark building in Toronto’s Corktown neighborhood, the firm is union of two distinct, yet complimentary voices. Adam Thom and Katja Aga Sachse Thom – partners in work and life – started the firm as an extension of a finely calibrated collaborative process built on a foundation of broad technical expertise and a dedication to craftsmanship.

During its first ten years, the firm received more than its fair share of media attention. Contradictory words like intimate, monumental, playful, daring, rugged, graceful, idiosyncratic and familiar were often used to describe the work. Over the next decade, the aim of the firm is to continue to beguile, confound and delight while taking on larger scale projects and building a team of like-minded associates and collaborators.

Katja Aga Sachse Thom


Danish by origin, Katja came to Toronto by way of Los Angeles where she met Adam and completed a M.Arch. at the Southern California Institute of Architecture (SCI-Arc). A modernist from birth, Katja comes from a long line of celebrated contemporary Danish textile designers. Her background as a weaver, sculptor (BFA – University of New Mexico), furniture designer and educator brings depth and wisdom to the architectural practice.

Adam Thom


Adam grew up in and around art, architecture and design. After obtaining a BFA in sculpture, he received a M.Arch. from the Southern California Institute of Architecture (SCI-Arc). He is a member of the Ontario Association of Architects, the RAIC and sits on the executive board for the Toronto Society of Architects. As a member of the advisory committee for IPLAN, a training program for internationally educated architects, he takes a keen interest in helping other architects gain a foothold in the profession.
