I think I'd go with
(add-after 'unpack 'move-source
  (lambda _
    (mkdir-p "foo/bar")
    (rename-file "my-project" "foo/bar/my-project")
  #t))

With that you'll be in <guix-build-temp> and you can chdir into whatever
directory you want. Or you could change the source so it doesn't expect
the source to be deep in a directory structure.
