An excellent 1/2 size replica. I commend it to the brethren. 😉
For those that are even more ambitious, and want "the real thing" (1:1 scale) can I recommend this site? https://tardisbuilders.com
For example, the Series 5 version :

A friend of mine used their plans to build his own replica, with a flashing blue light on top. It was a huge success at our village fete. Although (for some strange reason) some people came out looking disappointed that the replica was only a small wardrobe-like space inside. We did wonder what were they expecting?
An index of all known versions is here

Important note: these plans are only for the external shell. The inner workings are optional extras, especially a functional time rotor. I can neither confirm nor deny whether suitable parts are available from CPC Farnell (or other conveyors of fine electronic components). Now, if you'll excuse me, I've just got to nip back and give I.K.Brunel some tips on the Dawlish Avoiding Line.
