The plans: a new master suite, an updated kitchen and a renewed breezeway

We know we want to expand Linda out to add a master, but we're now waiting to hear back from city planning to know how much we can expand. Also, we know we have to completely redo the kitchen and small bath, as well as redo the breezeway (see image). There is a lot of work, but a lot of potential. These are the plans we've come up with as of January 4th.

Expansion of the Master would be 20' the rear (South) and 9'9" to the left (East) of the property.
The yellow dotted line is the current exterior wall of the house.
We would with this expansion make the second bedroom larger.

The kitchen above left would fit right into the existing old kitchen pocket, except of an opening at the bottom left, creating an open island onto the 'GREAT ROM" living space. The existing bath with shower on the right of the kitchen would remain as is to eliminate cost.
The Breezeway, on the right of bath and Dining room, has been turned into an extra room and a laundry room. It is set-back about four feet as the electric panel is on the side of the original house (see red box).

We've come up with the above designs with in mind trying to keep construction costs down. One big change we've planned for is to move the electric panel on the side of the garage, burying all wires underground, and allowing to push back window of room in breezeway to line up with the rest of the living/dining windows (see blue arrow above).
By the way, breezeways are very common in mid-century architecture found here in Palm Springs the breezeway was usually between the house and the carport/garage. You can see many photos here, where many have been converted to driveways or filled in as it has on our property to become an extra room in the house.
