hey dolsim,

here to make your work easily i am enlightining you on some of the key point differences between both the courses:

1. B arch is a technical course while B desg does not consider any engineering aspect to it.

2.B arch takes care of optimum usage of resources while B desg does not look in that asspect.

3. B arch deals with the design of the whole buildings or whole structures whereas B desg concentrates only on designing parts.

which one is better?

if you have a passion in designing then you can opt for B desgn while if you lean more towards technical drawings and stuffs then go for B arch.

however both these courses have their own pros and cons. both these courses have their own challenges too and have good compensation.

i suggest you to purely choose any one of them on the bis of your intersets.

all the best!
