will it be as good as this:

yes I do! I opened a thread on CP a while ago

No updates on the frame yet. I did pick up a 'donor' bicycle yesterday, a Colnago President. It features one the most beautiful Record groupsets Campagnolo ever made, namely because of its square taper carbon crankset. Aside for a couple of minor scuff marks, the bike was in mint condition, so I was really happy I was able to get it at a good price. I am not sure if the Eurus wheels will look the part, but they will do for the time being.

Hi Swijland, let me know if you decide against those Eurus wheels and would like to sell them, they're just what I'm after, thanks.

I am guessing the seat tube has not been cut yet in the last set of pictures. That said, I have fairly long legs, so I need a long seat tube. Actually, finding tubing that was long enough to do an integrated seat tube turned out to be pretty difficult. Here is a picture of a similar seat post design Kamil (form Kajak Custom) did on another build:
Concerning the geometry, you can find it below. From what I have been told, it is pretty standard road geometry.

Wow! Now I got the picture... Interesting! I assume that you want gears on it... Any specific reason for skipping the double triangle (narrower bb, crank clearance, cabling...) or is it more a tribute to Obree?
Another thing, did the framebuilder express any concern about the rigidity of the frame once used on the road?
As I have a similar design on mine I always been concern of using it on the road, I don't expect it to crack but sure I don't want to stress it too much.
Thanks -
Below are some new pictures of the build.
@Breso: the reason for skipping the double triangle is simply because I love the way it looks amazing IMHO. Kamil did express concerns about the rigidity. That is why, after some discussion, we choose to go with oversized non-butted tubing for the main and seat tube. Most folding bikes do feature a fairly similar design though, so I don't really expect it to be a real issue.

After thinking long and hard about the frame design and how it might affect the bottom bracket flex (thanks for sharing you insight Breso!), I decided to add a third tube to the front end in an effort to stiffen up the frame a bit without compromising the overall look of the frame too much.
Below is the updated geometry sheet.

About
Custom steel 'Old Faithful' build
Posted by

Ever since I got into cycling, I have been a big fan of retro time trial bikes. Particularly retro time trial bikes that have a frame design different from the standard double diamond shape, as dictated by the UCI nowadays. I have been meaning to buy one for a while now, but unfortunately they don't come up for sale very often.
The first unconventional bike I was able to get my hands on in the last couple of moths, was one made by a Pearson. I absolutely loved the way it looked, but unfortunately the frame ended up being too small for me.
After countless hours searching the web for possible options for a build without any results, I decided it was probably best to have a custom frame built. Finding a builder who was willing to do something different, was easier said than done though.
The frame I had in mind, was something similar to Graeme Obree's Old Faithful hour record bike, only fit for use as a regular road bike. Many variations to his design have been made by various builders. A vintage example is the one below by Dutch builder RIH. More recently Cherubim built a more artsy interpretation.
The first builder who was willing to give my idea a shot, was Kajak Custom. The owner, Malik, has done several really nice custom builds so far, so I am confident that he is the right man for the job. You can find some of his work on his Flickr account: https://www.flickr.com/photos/kajakcustom/.
After sending countless e-mails back and forth discussing which design and tubing would be best for the frame, we settled on 38.1 mm straight 0.9 mm straight gauge tubing for the main tube and the seat tube, and aero chain and seat stays. The frame will be filled brazed together. The frame will feature an integrated seatpost with a Thomson seat clamp. Cable routing will be external, in an effort to keep the main tube as strong as possible.
Here are the first pictures Kamil sent me of the build in progress.
