I would love to help but I can't see any pictures. Check your settings.

"Adjacency diagrams" are often called "bubble diagrams", but in either case they are simply ways to put onto paper all of the specific and finite spaces which are important to have included in the house. They can be large spaces, i.e., garage, living/family, etc., or small, i.e., pantry, guest closet, etc. They can be indoor, i.e., family room, etc., or outdoor, i.e., entertaining patio, BBQ, herb garden, etc. Whatever is important to the successful living for the house. Many architects use "bubbles" or circles of various size, sketched on tracing paper, large to small, and thereafter group them closely, where they are important to do so and place them independently if there are few or no important adjacencies. Adjacencies may be further defined with solid lines connecting bubbles (a "primary" adjacency); a dashed line (a "secondary" adjacency); or no connection meaning that the space or function is needed but has no strong or secondary connection to other spaces or functions. The purpose is to identify and establish agreement about a functional "wiring diagram" for the proposed house, which thereafter can act as a roadmap for the subsequent actual physical architectural design. As the architectural design progresses, it can be tested against the agreed upon adjacency diagram to evaluate how responsive and complete the design may be. In other words, are all the primary adjacencies in place; are the secondary adjacencies reasonable, and are the other uses accommodated somewhere? Every architect, being an individual, has her/his own preferred ways to design, of course, but this early approach to help guide, make design explorations more efficient and evaluate the design explorations is a common technique. Hope this helps.

Is there a specific reason that you need three garage doors all opening to the driveway? Our first house was a reasonable sized ranch house with a wide and extra deep two car garage (somewhere about 35 feet). A prior owner had grabbed 6 to 8 feet and added a breakfast room to the kitchen but the garage was full depth for 2/3 of the width. The sellers used the deep space for two cars swapping the fun car with the beater according to the season. We loved having all the space we wanted for the lawn tractor, workshop equipment and projects. The garage didn't look out of proportion to the house and only having a two car wide driveway limited the expense of maintenance and the fun of shoveling snow (I have since discovered the wonders of using a machine for that task!) I have seen several houses with a large front opening garage that also has single overhead door access to the rear or a double service door. Many time the outdoor tools and furniture are used at the opposite end of the lot from the driveway and the rear access makes it much easier to use and store those items. In my neighborhood there is a ranch house where the original garage was converted into a drive through garage with a double door front and back. Behind the attached garage the owners put a hard surface patio area and built a detached garage for his fun car storage and workshop space. I don't know if you are open to such ideas but flexibility can work for garage spaces just as it does inside the house.

This is a great thread for those contemplating building a new home. Clients are often bringing me sketches of floor plans or plans they've found online. Such plans can be helpful as a point of departure but almost always require a complete redo. What helps me more is a detailed conversation about lifestyle, philosophy of art and design, and a deep understanding of the site.
