Hi,
Depending how deep you want, to go you must
note that this one from ve2zaz (btw which is a great
design given it's simplicity) is a FLL not a PLL.
(unlike most of the others that really lock the phase of the
signal to the 10KHz or 1pps).

If you want to get your hands dirty, I'd suggest you to try VE2ZAZ's design.
I've built a few GPSDOs and this one is the one I liked most.

Do you actually want to build your own from scratch, or just buy something
like a Trimble Thunderbolt and add a PSU and housing?
If the latter then look for seller fluke.l (that's a lower case letter "L")
on eBay if you should want one right now, or if you aren't in a hurry wait
for the next "group buy" of these here.
If the former, how sophisticated do you want to get? These beesties can go
from real simple:

to really moderately complex such as:
<http://www.rt66.com/~shera/index_fs.htm>
I'm sure there have probably been more recent designs too that have gotten
even smarter ...

Hi there; being a new "Time nut" I'm looking for kit/project web sites &
info on building a GPSDO PLL.
Any info welcomed.
Ta Ray.
