Do you have a miracle engine in the garage? Then the rocket ship part
can be made of anything you want. Make it out of wood and wear a space
suit. Do you want to return to earth? Then I'd use titanium framing.
Does it need to be laser shielded? Then add a coating of pyrolitic
graphite to the skin. If you have the miracle engine then you can do
powered reentry, otherwise you're going to need an ablative heat
shield. Don't make the same mistake nasa made with all those intricate
tiles on the shuttle. Make it one big disposable thick disc of
pyrolized phenolic resin...
