Introspecture provides architectural services for high-performance small commercial and single-family TI, new construction, additions, and renovations. Introspecture evokes architectural introspection. It is design that is intentionally more quiet than brash. Design that is thoughtful and tailored to be lived and worked in, not just admired from afar. Introspecture architecture is respectful of the environment, in harmony with its surroundings, functional, efficient, and beautiful.

Pathway Design & Construction is committed to preserving the existing character of both the home and neighborhood while offering environmentally friendly conveniences desired by today's modern families.

I am a retired residential architect with thirty years experience running my own company. I focus exclusively on consultations, which are great for: Initial feasibility, Cost estimates, DIYers. My consult includes the re-design of one floor of your house. I produce a hand sketch drawn to scale that contractors can use for a cost estimate.
