For Architects
By Architects

Most architects don’t love writing specifications.
We do.

From Big Ideas to Fine Print

Bjorn Architecture ensures specifications are clear, contractor-ready, and aligned with your design intent. As a licensed architectural practice, we understand the realities of your projects—not just the paperwork.

We stay ahead of industry shifts, refining our master specifications to meet evolving materials and sustainability standards. We handle the wording so your design is built as intended.

The Team

Gregory Wilson | Principal

I'm a Registered Architect in Western Australia (3598), New South Wales (12226), and British Columbia (L3598). I have deep expertise in design, project delivery, and specification writing. I ensure specifications are precise and well-coordinated and support your design through construction.

With formal training in specification writing, I seamlessly integrate evolving sustainability standards like GreenStar, LEED, and Passivhaus into projects. My work is built on confidentiality, integrity, and independence—always serving your design intent.

Accountability

We believe specification writing is serious business, and should be performed only by registered practitioners (see the Shergold Weir report). The company maintains professional registrations and licensing, and stays accountable to their ethical requirements and professional codes of practice.

Registration and Licenses

Professional Integrity

We prioritise confidentiality and avoid conflicts of interest. We believe that accepting payment from manufacturers and suppliers to curate their products in our Master Specifications or on our website crosses an ethical boundary.

Our Testimonials

  • T. Maginnis Cocivera
    We worked with Gregory on a large design-driven, sustainability-focused project. It was a huge undertaking for a small firm like ours, but Gregory provided outstanding specification writing assistance that enabled us to fully realize our design vision. He understood the nuances of our work — from high-performance glazing and building envelope, to the careful specifying of finishes that supported our environmental goals — and brought a thoughtful, well-informed approach to every section of the specification. As a fellow small practice, we appreciated his clear communication, collaborative style, and ability to anticipate our needs. He is very reliable and was always there to provide assistance, especially through the pressure of the final deadlines. We would gladly work with him again.
