That layout would drive me crazy — it's a big kitchen, but the only space to prep is in the weird angled dishwasher and stretch of counter to the left of it. Open the dishwasher, and your prep space is gone. Meanwhile, the range is crammed into a claustrophobic space between the wall ovens and pantry, with only 18" on each side. (And plus, the angles on the island feel haphazard and with the slanted sections not really lined up with each other)

Here's a couple quick ideas here with big rectangular islands. Both given you a primary and secondary prep space, while also giving you a separate clean-up space. Downside is that pantry space suffers a bit — you lose the corner pantry, but I tried to make up for that by creating 6 foot section of pantry cabinets.

I'll let those more knowledgeable chime in on the kitchen. Did want to suggest that the master and bottom right bedroom get swapped. That way the master could have windows on two walls.

Matt, I agree with everything you said. I would never be able to function with that kitchen layout. BUT there is no exterior wall to the kitchen so the main sink would be up against a wall, which I can't live with either. Any thoughts on that?

I like Matt's ideas. In these layouts, the main prep space would be on the island, so the idea is that you spend more time prepping with the view into the great room. Also clean-up sink and DW on the island puts dirty dishes front and center.

Here's smm5525's amazing kitchen where she eliminated the corner pantry.

I'm not a fan of angled islands at all. I would put the prep sink on island and make it rectangular. Also eliminate the corner pantry in favor of cabinets with shallower shelves. Thx Caligirl!

Maybe cleanup sink on the island and prep on the peninsula?

I'm thinking 12" deep and 42" high cabs on the DR side of the island, so dirty dishes would not be seen from the dining table.

I had that angled counter for 18 years. I hated it. It was too far away to use for prepping, but it was great hang out serving area in the kitchen. That was the only plus to it. My stove top was where you have B45 and the corner closet was where a corner sink (yes, another issue) was placed. So, I had about the same space to prep that shows in your plan. It was awful.

In our current plan the island is straight and useful this time. And I added a sink to the island.

Rectangular and square islands are easy to design. You can vary one or more sides to fit into your larger overall kitchen or opened space design. Our island is a facetted half circle with 21" facets and a matching drop ceiling section above to lower the 10' ceiling in the larger area as one way to separate the kitchen out. This takes more design and construction effort without a doubt.

I am a fabricator. We do jumbo angled island all the time. Overall the layout preference is personal but be careful not to make it so deep you can't reach the middle for cleaning. You'd also need a seam in that island which should be discussed in detail with the fabricator.

Also, if you do granite consider have side(s) of the island cabinet facing the large room covered with stone as well. This is a very nice effect I did in my own home.

In your layout with the garage and hallway adjacent to the kitchen I would have sky lights or some other means to introduce a significant amount of natural light into the kitchen area.

I lived with an angle island exactly your size for 19 yrs and it was a nightmare. We had no counter space and it blocked all entry into the main kitchen proper. Only one person could work there at any one time.

It may look nice but awful for functionality.

Most of the angled islands are see are dreadful. That one is particularly "dreadful-er" than most - with it's overall imbalance and odd angles. If the architect drew it - I would question his or her sense of design.
