Hear it from our clients first:
Eric with Boldera delivered five-star service and results for our project. We couldn't be more pleased with the results.
I found him to be transparent with the contract terms, attentive as we planned, patient as I worked through decisions and changed my mind, a very good listener and open to input. Importantly he was very responsive — with deliverables coming in on time or sooner which I find is rare. Hi style speaks for itself. We would definitely use him again.
Boldera has created an incredible design concept package, including zoning and by-law analysis, detailed site plans, and inspiration images for a large-scale Toronto renovation and addition.
Our clients are in great hands with such a skilled team behind the design of their custom home.
I had the pleasure of working with Boldera on a custom home design. I have worked with other designers in the past and was really surprised with the level of detail in their work.
Not only did they provide amazing design, but were also very accommodating and patient with the home owners. Eric is one of the most creative designers that I have worked with.
Rethinking Architecture,
Sustainably.
