Check out https://wiki.ubuntu.com/SimpleSbuild for this, too!

RAOF, maybe you could add some of your tweaks there? Love the optional 
local repo and dynamic proxy.

There's more, too, you can x-build for devices this way, quite a lot 
faster than natively on devices. Unfortunately that breaks often, 'cause 
it's not part of our daily routine. Currently it's broken due to the 
forced 4.9 dependency¹.

Other available niceties include: shm (whole build happens in RAM), 
ccache (shared between chroots and chroot runs), you can create 
pre-populated chroots with all the build deps for your project 
preinstalled (I use btrfs snapshots for those to save space). The world 
is your oyster!
