We had the 36 foot (HAH) AG Wolf in our last house. We loved the unit and space up top but did often run out of burner space. The 36 inch oven was nice and held a lot which was great as long as we were cooking things at the same temp which we rarely ever did. Next, that oven took forever to preheat... 40-45 minutes to 400. Lastly, we think b/c of its huge capacity, it cooked really hot. I think the burners had to run a lot to keep it at temp which over cooked bottoms of breads etc. Great for roasts and some other things but not for breads, cookies, pastries etc. In the end though, we were VERY pleased with the Wolf. We adapted to the hot temps by using additional pans for heat shields and adjusting the temps. In our current house, we went with a 60 inch AG Blue Star range. It has 2 30 inch ovens, 8 burners and a grill. We also put in a Wolf 30 inch wall oven. The preheat on all 3 ovens to 400 is about 15-20 minutes. The first cookies and corn bread we did in the gas ovens. They were better than in the 36" Wolf but still cooked pretty hard. Next time I did corn bread, I thought, Oh yeah, I've got the wall oven and used it... a world of difference. Since then we have done biscuits and other items and they come out perfectly. We still find the gas is great for roasts, casseroles, reheating etc. We may have a bit of over kill, but due to advice from this forum, we specifically diversified to both gas and electric and have been very pleased. So, my recommendation? The 48 inch AG range AND an electric wall oven. Oh yeah, the grill on the BS is killer. I got talked into it as a last minute decision and thought I would use it occasionally. We have used it a fair amount so fay and it does a killer job on veggies and chicken. We have elected to limit the grill to those items only. Beef and fish are too messy and when we grill those, its always outside (so far). I have found a griddle plate that fits nicely over the grill to convert it to a griddle when needed.

I think I would go with two smaller ovens rather then one huge one. A 36" one would take forever to preheat, even if you were cooking something small. My friend with one now almost exclusively uses a high-end toaster oven instead- and her expensive oven sits most of the time. Maybe an additional oven with a special function- like the Advantium or Miele steam oven.

We bought the Miele Combi Steam in addition to a 30" wall oven, and it is our "Go To" Oven. Use it daily. It is very versatile and being a smaller oven heats quickly. All of our baking dishes fit in this oven. It operates the same as our 30" wall oven plus the combi steam function. It is awesome for reheating leftovers/baking bread/used as a regular oven/steaming veggies- rice etc. The Miele has a broiler unlike the Wolf - not sure of your configuration but you might want to compare the Miele with the Wolf. There are several threads on these two products. Regardless of which oven - you will be happy going with a combi steam oven. Agree with the other posters that recommend you attend a demo at a Wolf/Miele design center if possible.

If this is a fancy house and you intend to sell soon OR you do a lot of involved cooking for a lot of people or with large-format cookware and need 36” I would get that; either way, get a brand you have cooked on before so you know you like it. (My family test-drove new ranges through cooking classes—with COVID lightening up this is a possibility for many people again.) Also remember that big ranges come with big hoods, and the bigger it is, the more it looks like a restaurant or a bioscience lab. Also, looks like you are redesigning your kitchen and dropping a lot of money. I may be misreading, but it looks like whomever designed your kitchen put a sink over an undercounter refrigerator. If this is true, you may want to hire someone else to do this plan for you.
