What exactly are you asking? It looks fine as it is to me for the space you have . I have to say I would not give up living space for a huge garage and for sure not in CA

Looks spacious from my 1920s small house perspective. i’m all about small bedrooms and more common space in small houses so i wouldn’t add more. are you unhPpy with anything specifically?

Is this a new build? DH grew up in So Cal, so I know it is normal to have a small house and a two car garage, but Patricia's comment is still food for thought. You are probably working within the constraints of a small lot and required setbacks, so if this is maximizing the lot I assume you don't have the ability to bump out anywhere. It looks like pretty efficient use of the cube to me. The only thing I would think about is whether you really need island seating when the table is right there. I don't know what the dimension is between the island seating and the sofa pictured, but it looks tight. Since the drawing is cutoff I can't determine if there is possibly another way you could arrange the furniture in that area. A cube is also an efficient way to build as far as construction costs, so that's a plus.

It looks like a good floor plan to me. The master bedroom isn’t large, but you have generous closet space. I personally wouldn’t give up the extra garage space because of the bicycles etc that accumulate. I also wouldn’t give up the counter seating. Even though there is nearby eating area, the counter seating is great for guests or family to sit at while someone is cooking.

Thank you all for your expert feedback! This is a 1000 sq
foot remodel and addition of 500 sq feet (limited to 500 sq feet by the city). The
snapshot I provided is of the remodeled portion. Because of the city's rules,
we felt there was no benefit to pulling the garage into the sq footage at this
time. We plan on carving part of the garage for a laundry area and a flex space
for the kids to play/do crafts. Due to the city only allowing us to
add 500 feet we ended up moving more walls than we originally expected.

We live in an area where street parking is limited so we like
the option of parking in the garage for the few instances where we must.

If I had any specific questions they would be:

1. I wondered if those more familiar than myself would suggest reconsidering
   the 5-foot-wide walk-in closet. I looked at pictures of 5-foot-wide closets and
   they look a bit tight. My limited experience did not result in me seeing a way to
   improve, so I thought I’d ask here.
2. I also wonder if two sinks in the primary bath are necessary. I’d rather have the counter & storage space, but I feel this may be a
   resale must.

As
we get closer to making final decisions my doubts are kicking in. Once we get started I will not be one of those people who changes her mind! My biggest concern is not using the limited
space we have well. I thought I’d put it out there to see if there were options
I did not even think to consider. So, thank you all for your kind input.

No closet recommendations - mine is under 5’ and feels spacious compared to the inaccessible 1920s original! definitely double sink not required in my area of small houses - even most newly remodeled houses do not have them, and people are thrilled just to have 2 full baths. in general i do not think double sinks is a good use of space in 1500 sf. i’d look at comps though. full disclosure: i put a new wall hung sink in my bathroom haha.

I would keep the double sinks, unless the master is only used by one person. By eliminating one, you gain a little bit of drawer space and some counter space. The extra counter space is an invitation for clutter! So, I would keep them and make sure to have two medicine cabinet mirrors above them.

Where I live, everybody wants double sinks even in 1000sf townhouses! But if you expect to live there a while, set it up whatever way works for *you*, as fashions will likely have changed in a decade anyway...

Your master suite looks fine as it is

You could think about a wall of reach in Pax closets and gain a bit of space . I do find a 5' wide walkin pretty tight .
