Chemistry is not required for Architecture but I would recommend looking into the different courses and universities to see what their entry requirements are. If you are looking more into a design based Architecture degree for your Part 1 than they will ask you for a portfolio of work to see how well you can draw as well as your skills. Apart from that they would also want to know that you can work beyond what has already been made and that you do critical analysis while working on your projects showing a broader sense of architecture. This would be through reading an architectural journal or magazine.
I'm currently a design student at Ravensbourne and I thought you might like to hear a bit about our BA Architecture course. We also have a BA Urban Landscape Architecture and BA Interior Design Environmental Architecture course as well. All in which you can get your Part 1 of Architecture. They are all taught by industry professionals and our students go on to regularly win awards. Although we are mostly design based you will also learn the technical and theoretical side of architecture to help you dig deeper into your analysis to become a better designer.
Ravensbourne is a specialist digital design and media university located in North Greenwich, London. Since we are a specialist we are very industry focused meaning that you will be given industry briefs as well as doing collaborative and competition briefs.
I have a friend who is currently on her final year of the BA Architecture course and she has loved her time on the course. She was telling me how they go on trips abroad at least once a year to do projects outside of the UK and with our Prototyping facilities it has made her experience even better.
If you would like to know more about the University or hear directly from the Architecture students I would recommend coming to an open day. You will be able to meet the tutors and students while also getting help on your portfolio though our portfolio workshops.
I hope this helps and if you have any other questions please feel free to let me know,
