Walnut tree guild on small urban landscape?

I am looking at some of the tree guilds suggesting in Gaia's Garden.  I would love to be able to combine some fruit tree guilds with a Walnut guild.  However I live in suburbia on a typical city postage stamp.  Can I realistically fit a walnut guild with one or two apple or fruit tree guilds into a space like this?  What are your experiences with trying to fit trees of this size into this type of landscape once you start adding the companion trees and plants?

are you thinking black or english walnuts? I think black walnuts are to messy to be close to house. those husks will stain everything.
maybe try hazelnuts? they don't get as big and are more friendly to other plants

I was thinking about the English Walnuts.  Your right the black walnuts are pretty messy.  The concern is it looks like I need to calculate a 30 foot canopy for a tree this size so that really makes the space tight by the time you add Black Locust, Mulberry and the start thinking about a apple or fruit guild... So I am wondering if I can realistically make a nut tree work on a small space.  Also I live in a high plains desert so it needs to be a nut tree that can handle this type of environment.  It looks like Walnut should be able to grow here, but I am concerned about the space needed to realistically have that guild, companions, and other fruit guilds I want.  So I was wondering what others hand done.

Thanks for the input on the Hazelnut.  I will have to check into that.

if you can place your walnut more than 50 feet away from your apple you might be able to do both, but walnuts also need a pollinator

I think the more that I am looking at the space I have available that the walnut tree is likely not going to fit this postage stamp sized city lot and work for me.  I am thinking that I will probably just try the honey locust and mulberry trees with some dwarf or semi dwarf fruit trees.  Even that will be pretty crowded, but I think it might be doable.  My plan is evolving as I am out digging and working in the yard and as I am reading.  So as much as I would like to have a nut tree on the property I think I have to be realistic with the space I have available.  So I think I will use the locust and mulberry as my top story, the semi dwarf or dwarf fruit trees as the lower story, then layer bushes and berries under that starting from the downhill side of the property with the tallest and work up the hill with the shorter plants.  Now I think I need to figure out the layout, and the water needs for this.  Living in a desert kinda sucks!
