There's not much to tell that's actually concrete. Annúminas has been a ruin for two thousand years. It was never described in any detail, but multiple details can be inferred.

It had a principal tower, like the great cities of Gondor. It was built (obviously) on the shores of Lake Evendim, with the Hills of Evendim overlooking it. Some aspect of it is related to the west/ sunset. Perhaps this is because it is in the West of Middle-earth, though that seems the least likely explanation. Possibly it was oriented to the west, or the tower is in the west. It could have a particularly spectacular view of the sunset. Any number of theories is possible, and I'm sure that you can think of a feature.

Most of the things we actually know about Annúminas (the Sceptre and the palantír) are gone at the time of the War of the Ring. No Rangers live there as in Norbury of the Kings. There is a lot of freedom in your design, including the materials that you should use and your building style. Though for the latter, you may want to find Tolkien's descriptions of the cities of the southern Dúnedain, as they had the same building style, and were described in greater detail in The Lord of the Rings.
