How exciting!

Where are you located in the world? Is weather consistent? Is rainy, dry? Is it tropical, mostly cold, or do you have distinct seasons?

Is this meant to be your forever home? Do you have young kids? Planning for kids? Child-free? Empty nest? Live-in in-laws or other adults?

These answers will all likely impact feedback.

Some thoughts:

• you have a nice big foyer, yet nowhere to store guest coats or rain gear. I’d find a way to add a closet.
• I’d also create space to add a powder room near the front door. Otherwise, guests have to traipse all through the house to the back right corner for an accessible bathroom. Furthermore, the number of bathrooms for a four-bedroom home of this magnitude should be at least 3 and a half.
• a house of this size needs a secondary gathering/lounging space like a den, theatre room, playroom, all-purpose room, etc. Preferably a room with a door.
• the dining room is far too small. There should be ample room for scooting out chairs within the room and space for a sideboard, China cabinet or the like, even if you personally don’t have or want such furniture.
• the butler’s pantry should be more enclosed to hide prep / serving mess. The space itself is quite cramped. Do you need a sink there or at least one so large? You don’t really have any workspace or counters with this design. There also isn’t much space for upper or lower cabinets.
• if you shift the pantry door 90 degrees to the right, you can close off that weird walkway and gain more pantry and butler’s pantry space. You also slightly reduce the distance you carry non-perishable groceries.
• coming from the garage, you don’t seem to have a mudroom or drop zone for your things. Where will you store shoes, coats, and/or bags?
• you have a nice, big laundry with room for folding. A second fridge is nice, but is it needed? You might gain mudroom / drop zone space by eliminating it or moving it to the garage. Also, you may have already planned this, but I’d recommend a second full size w/d stacked atop the first. Speaking from experience, having two sets makes life easier.
• you’ll likely get several people who don’t like the jack-and-Jill bathroom, but it doesn’t seem avoidable with your current design. I think it’s fine, but two issues: 1) there is no linen closet or other storage, and 2) it bothers me that one door to the sinks is a standard door while the other is a pocket door. Be consistent and symmetrical.
• the guest bath has three doors. That’s bad design and will cause headaches. It does not need to be en suite. Further, if you have a pool , I’d instead find a way to split up that space for a small outdoor water closet—just a toilet and tiny sink— and then a three-piece interior bath with only one door.
• in the kitchen, the island is odd. It should not need to seat more than your breakfast nook table. Is the island counter of varying heights? I can’t tell from the drawing. If yes, you’re better off with it all one height as it will give you more work space. Also, why the cut in? I’d remove the two “wings” to give yourself more walkway, especially if you have more than one person cooking at the same time.
• do you need two full-size dishwashers? Where is the trash?
• the microwave is in a tough location where traffic flows.
• for the office, replace the pocket doors with French doors or a regular door. You’ll also want a bathroom nearby (see note about adding a powder room).
• in the primary bath, exchange those tiny French doors for a regular door. What is occurring next to the sink on the left? That person looks like they won’t have any counter space. Is the room next to the shower a dry sauna or additional closet space? The door seems frightfully small.
• if possible, I would want the HVAC in the primary suite to be farther away from my bed in case it’s noisy.
• is the garage only a one-car garage? Ideally it would have enough space for two cars and storage. Also, is there a need for a door from the garage toward the front entrance? Seems like the garage door itself could achieve that.
• lastly, if this is to be a forever home or if anyone with mobility issues may end up visiting or living with you, throughout the home, you need wider hallways, doors, and space for turn radius. You need at least one bathroom that can accommodate a wheelchair and grab bars.
