How can I connect 2 monitors/mice/keyboard to 1 PC over a LAN?

I want to put a computer in the basement for my recording studio. I also want to connect and operate the same computer whilst in the attic of the house. The connections for the keyboard, mouse and monitor in the studio can be made directly to the computer. The connection to the PC, and control of the PC from the attic must be made only via a LAN cable. Does anyone have any thoughts how this can be achieved?
Thank you..
