Thank you for the opportunity to submit a proposal for your project. After analyzing your program I made some basic design decisions.
First I added a new wing to the right side on the plan. Based on the program, existing space, and budget I felt a single addition at one side was the most economically prudent solution.
I turned the new wing at 90 degrees to create an “L” shape plan providing an opposing gable that I think provides architectural interest. I also shifted the new wing so that it offset from the existing structure to again create a more interesting plan and allow for corner exposure of the existing house.
On the main floor I placed a single large volume space containing a Family/Kitchen/Dining Room. This space could have vaulted ceilings taking advantage of the gable roof. At one end is a large Family Room with stone fireplace and wrapped on 2 sides with french doors and tall windows facing the view. A deck off this area would connect back to the main house.
A large Kitchen/Dining area anchors the other end with a generous island in the center and wrapped with counters on 2 sides. I imagine the center island with a raised bar and large farm sink for entertaining, while the opposite wall would have a large range with counters each side. At the end would be another counter area with a second sink located at the window affording views. To the right is a dining area with tall windows offering additional views, so the room is essentially wrapped with glass on 3 sides.
At the corner is a walk-n pantry, and tucked into the corner could be a windy stair accessing a small loft area located above.
In the existing house I utilized the existing kitchen and along with bumping out to encompass some of the existing porch to accommodate a new entry space, mud room, powder room and laundry. At the end I imagine the existing living area serving as a sitting area that might contain the piano.
I decided to maintain the existing stair, both for economic reasons, and also I felt it worked fine with the new plan.
I opted to enlarge the master suite to encompass the entire left side of the plan. I essentially utilized the office space to create 2 large walk-in closets., then expanded the master bath into the available space. You could as an option even have a door directly into the laundry. I also bumped out the bath onto part of the existing porch to provide space for a tub.
Utilizing the stair down to the lower level, I would simply eliminate the entry door and replace with a tall window.
On the lower level, I would keep the one bedroom, bath and mech space as is. I would then suggest converting existing den into 2 separate but connected rooms serving as a man cave and office. A corridor bisecting these would connect to the new wing. Since this space would be open to grade on 2 sides, I located 2 large rooms here. At one end would be a large bedroom/craft room with glass doors out to a covered terrace.
At the opposite end would be another large bedroom. I suggest as an option that this could actually serve as an in-law type suite with its own outside entrance. (you could perhaps rough in a bath/kitchen area as an option for future phase)
As a final note, I wanted to let you know that I scrambled to submit a proposal by the original deadline. Ultimately the final renderings were not quite complete as I hoped. I hope though that the thought I put into the planning was clear. I had hoped to have time to add more detail and time to the proposal within in the additional timeframe, but other work obligations prevented me from getting back to this. So hopefully you will find my proposal to your liking. As in most projects I find, there is often a lot of back-and-forth with the client on details. In that vein if you are inclined to select my proposal, I would happy to offer some complimentary time to fine tune the plan to your liking. I own and operate and full service architectural design build company and am confident we could provide any service you may require.
