Mark Dudek lives his digital life as a skilled assassin in medieval Jerusalem. Or a star international footballer. Of course, he really only got the PS3 for the kids …

What books have you bought online?

Nudge by Richard H Thaler and Cass R Sunstein. It’s about designing environments that make it easier for people to choose what’s best for them, their families and their society. And The Damned United, David Peace’s book on Leeds United, to support my sporting life.

What shall we play?

Pro Evolution Soccer on PlayStation 3. I play it with my older son and the graphics are excellent. Also Assassin’s Creed, set in Jerusalem during the Crusades, as I like the idea of being a fighter in a medieval city. It’s massively un-PC, of course, but I got into it with my children and am now hooked.

What’s your favourite bookmark?

It’s I design school buildings, and dealing with the whole sustainability issue is like grappling with a slippery eel. This website explains what options are available.

It’s also an architect-friendly site and visually very accessible.

What do you buy online?

I’m looking for a little wooden sailing dinghy. We go to the seaside every year and it’s a really good introduction to sailing for children.

What track is most played on your iTunes?

Closing Time by Tom Waits – melodic but never sentimental. And Spem in Alium, a 40-part motet by Thomas Tallis. When I have it on loud on headphones, it allows me to concentrate and cut myself off.

What TV programmes have you downloaded recently?

Charles Wheeler’s classic documentary on John F Kennedy (pictured). Wheeler was a fantastic reporter who framed international events over a 60-year period.

What’s in your digital holster?

An iPhone. I find it visually stimulating, and I use its camera constantly when on site. I also particularly like taking photos of my two young children, as I’m tracking them as they grow up, using them as a sort of research project to understand how they use the urban environment.
