With a nice, hilly and green countryside to gaze at, this par 72 plays very smoothly and is quite challenging, at times, with its elevation changes, water hazards and blind shots toward its (mostly) small greens.
Right off the bat, you will face a pretty par-5 opening hole, with a risky and long approach over a lake to get to the green (and a flag real close to it), before moving later on to the dogleg right par-4 3rd, with two blind shots to reach its downhill green.
Another par-5 hole awaits you with the dogleg right 6th, with a downhill green, potentially reachable on your second shot if you can avoid the crescent-shaped bunker (on its left), and a smaller bunker (on the right), before walking over to the tricky par-3 8th, with branches sticking out not too far from the tee box (on the right), hiding a small lake behind over which you will have to hit your tee shot to reach the downhill and undulated green.
Two dogleg left holes follow, with the wide open 9th, having a big tree on the left of the tee box and needing an uphill approach to the green, and the 10th, requiring a blind and uphill tee shot over tall grass landing onto a narrow fairway and an approach downward to the green.
The dogleg right par-5 11th hole, on another hand, is downhill all the way with a blind tee shot and a long second shot toward a narrow green, and is followed by the nice par-3 12th, with a tee shot flying across a small lake in the direction of the green, and the short dogleg par-5 13th, with a blind and uphill tee shot landing downhill past a huge bunker (in the inner corner), and a tricky downhill approach over a lake, partially hidden by a big tree (on the left) to get to the green.
Then, after the challenging par-3 17th hole, steeply uphill, you will finish with the dogleg right par-5 18th, with an uphill tee shot landing short of a path, splitting the fairway, and a pretty downhill (and blind) approach to the green, surrounded by a clubhouse, a parking lot and a few tents.
Overall, this Int'l @London GC course, well-designed by the CGX team, will test your skills but, with birdie or eagle opportunities on all par-5 holes, you should be able to finish below par, be it on this A version or the B one...

As you can see there is a A and B version of this course, both versions are the same, only the flag position on the green is different.

Important note: a lot of CGX courses are only playable from the: PRO tees
The cgx designers created courses in high tempo, so they only made the pro tees playable.
So in TW08 you have to select the PRO tees.

Another note: Maybe there are versions of these courses already on Coursedownloads by others, most of whom were designers on the CGX Design Team.
