I see design as a synthesis of many great ideas which have, not always, but often, come before. I've said it many times; you need to learn to walk before you can run. It's important to find a balance between innovation/"new" ideas and synthesis of tried-and-true methods.
That said, I agree to a degree, and feel that over time I need to push myself to develop a more "delightful" aesthetic. But I've found a lot of success in school because of the way I synthesize the many ideas I stumble across in school and in my self-study. I've had a lot of successful critiques for my designs, and I attribute my design success to my design sense and a big part of that is my ability to synthesize ideas clearly, not pass of shmaltzy design as something new and unique (when it doesn't function as well and when it's been done before anyway!). I don't like disingenuous designers. Most critiques I see, 90% of what the designers do is bullshitting. I believe that my work is different than that, and so for now, I will continue on the path I've been working.
With each design, I push myself further. Maybe one day I'll post something that is more "out there" that you will appreciate*. Until then, please respect that my designs take a constant back-and-forth between instructor and student, between designer and critic, between structure and various other considerations. It's a massive process, and it's disingenuous to write it off because you don't like the aesthetic. Architecture is a function of numerous variables; aesthetics are one of many factors.
Anyways, I think/hope I've made my point.
(*A lot of "out there" architecture, however, receives lots of praise from the press, but is known to the architectural community to perform poorly. A lot of Zaha Hadid's work is original in many ways, but is crap. That said, even many of the architectural greats were synthesizing ideas created by others over time. Don't assume that just the work you recognize is "copied" from other architects. Architecture from all around the world and in different regions borrows its ideas from elsewhere. And architecture in Toronto often has similar visual themes because of what the climate and code demand. You can't take all the ideas from a building in Barcelona and assume they would work here. We just can't achieve the same "lightness" of elements that warmer climates can, for example. It's very understandable that certain design features become more popular or "re-used" in certain regions.)
