include the work you ave, to the best of your ability.  Unless the earlier work isn't that great or you want to enhance your skills I wouldn't worry about new computer models. 

just my opinion...

Portfolio is about quality, not quantity. Include only your best work, but very thoroughly. If you believe that you have an edge over other applicants in a skill set, show it off.

That's basically the self-made guideline I followed.

I think it's important to show some hand drawing, mostly at the level of conceptual diagrams, if your skills are particularly strong. I think that would certainly set you apart compared to those designers that only have computer skills.

computer skills won't matter unless you are applying to school that specialises in computation design.  and even then it probably wouldn't be the deciding point.

try to show what you think and how you translate your thoughts into built forms and concepts.  showing that you are self-aware about your work is the best selling-point i can think of.  if you got that sorted then no one will worry about the models and drawings being by hand or by computer.

huh, what schools that don't do computation?

are they good?

yeah, i thought so.

anyone can do computational/algorithmic design.  lots of schools don't make it their thing, and many that do are not uptight about computer skills, cuz they are more interested in what you do with the skills than being a technician.  i wouldn't worry about it.  much more important to have a direction.

as far as schools being good without computation...currently i'm teaching a studio with kazuyo sejima at keio university, working on reconstruction project in tohoku region.  students can use computers or not.  we really don't care.  there is a need to have some insight into what the architecture is about though.  so that is what we are teaching.  we have all the same machines for 3d printing and laser cutting and so on, but it isn't the main drive of the program...i don't think it is a bad education as a result.

Will, could you expand more on the part of being "self-aware of my work". I find that an interesting point... I've been going through my work trying to pick out the best projects from my past 3 years.

Thanks for all the input so far.

keio: the harvard of... yeah. ok.

keio is totally un-famous outside Japan.  that's the cool part. shigeru ban developed his paper tube architecture here, and kuma also was prof til last year.  now we have fumihiko maki and kazuyo sejima as the guest stars (if that matters).  students are pretty good, education is very good if you don't mind working in the field and building stuff every once in awhile...

for what it's worth i did my phd at u of tokyo, which is maybe a bit more famous.  it was very good education and barely a computer in sight when i was there (5 years ago).  it's got an amazing computation program now with yusuke obuchi teaching, but none of what he teaches is based on being a technician.  its all idea driven.

which is my point about being self aware.  it's very hard thing to do but the most impressive portfolios, and the most impressive students from my perspective, are the ones who are working towards a particular goal and know exactly what the value of their work is, and the context they are working in.  if you are making a portfolio it should tell a story about what you think architecture is - what it is for and why it's worth doing. 

if that happens to be all about computation then cool, but it is not necessary to have any computer renderings or algorithmic experimentation if your work is about something that won't benefit from that stuff.  i guess the hard thing is to figure out if it is necessary for your own work.  but in itself computer skills don't say much, especially nowadays when they are so ubiquitous...

Thanks Will! That really does help. Obviously I have a much reflecting to do over this summer so I can truly understand what architecture is for me and why it's worth doing. Thanks again for the input!
