A Rare Combination

Architecture and general contracting.

Most ADU builds require you to hire two separate professionals and hope they communicate. John is both. One contract. One point of accountability. One person who has stood on your property, drawn your plans, and will run the build.

The usual way
  • A drawing is imagined by one mind.
  • The house build is managed by another.
  • This means more coordination work for the client and more potential for problems.
Working with John
  • One mind imagines the house.
  • A streamlined design-build process with the same person.
  • The vision comes to life with fewer steps for the client from start to finish.

Why an ADU

A second home
on your property.

Hand-drawn elevation sketch of an ADU by John Kinstle

An ADU is a new possibility for your home. A new vision of what your property can hold: a place for a parent to grow older near family, a private space for a grown child, a studio at the end of the garden, or, a rental that pays the house back, year after year.

  • For family

    A way to keep the people you love close, without losing your privacy.

  • For income

    A new asset or income generator on the land you already own.

  • For the years ahead

    An office now, a guest house later. A home for your own old age, when the time comes.

  • For the house itself

    Built in the spirit of the original, so it blends well with your existing property instead of feeling added-onto.

The best ADUs don't look added. They look like they were always meant to be there.

Why John

From drafting board
to job site.

For most of his career John didn't only design homes and ADUs, he built them. Fifty years on, he still has a General Contractor license and he's built relationships with the best subcontractors in the industry. He may have hung up his literal tool belt, but he still shows up in the morning ready to manage the vision, and the build, from start to finish.

In John's words
“I've always worn the toolbelt and led the crew on site. By being there every day I could truly design the project, from start to finish, down to the last detail.”
