Help planning layout for large pond with bog filter in two-tier backyard

[twd000]

Trying to figure out a layout that makes sense for my backyard pond.

Desire to incorporate these elements:
-20'x30'x3' pond
-10'x15'x3' planted bog filter
-meandering stream near the porch steps
-waterfall facing the patio/house
-wood deck overhanging deep end of the pond

I read the Aquascape design guidelines and agree with bringing the pond as close to the house as possible. They recommend bringing the water level to within 2" of the patio.

The viewing points will be:
-back patio
-screen porch
-kitchen window

The double-trunk maple tree will be removed of course.

There is a significant 4'+ dropoff you see from the patio to the lower lawn. I thought this would be an advantage but now I'm wondering how I will get enough fill to build the berm on the backside, while blending it into the landscape? The waterfall should be on that backside facing the house which means I need to build up that berm significantly higher than the front.
I also can't figure out where to site the bog filter. I plan to fill it with plants so it will look appealing. Should that go near the front of the screen porch? I will have to fill that area to get it to gravity drain back into the pond.

Hello and welcome!

Just curious, but why does Aquascape recommend putting the pond as close to the house as possible?

paraphrasing here, but the idea is that you spend most time in or near the house. Some people put the pond far away and don't use it/ enjoy it as much
