Laptop for UK Architecture Student

Looking for a laptop for a UK-based Architecture student, for running CAD programmes detail below.

Thanks in advance for your help!

Total budget (in local currency) and country of purchase: £1000-£1500 (ideally cheaper end of the scale, will also hopefully trade in old laptop to get money off)

Are you open to refurbs/used? Yes

How would you prioritize form factor (ultrabook, 2-in-1, etc.), build quality, performance, and battery life? Main priority is performance, build quality and longevity (maybe upgradable).

How important is weight and thinness to you? Not a huge factor, but will be transporting to/from uni regularly

Do you have a preferred screen size? If indifferent, put N/A. 15” or bigger

Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run. Mainly CAD/design software: AutoCad, ArchiCad, SketchUp, Adobe suite, Twinmotion, Vray

If you're gaming, do you have certain games you want to play? At what settings and FPS do you want? N/A

Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)? N/A

Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion.
