I would enjoy completely customizable Living Quarters for guardians. They could require resources to build certain larger or more advanced rooms. Furnishings could be added using the same resources. Armories could be built to use as display rooms for our prized weapons and armor, and to gear up. Trophy rooms to view 3D evidence of our accomplishments. In game clan support would be great and clan halls could be built the same way, officers could even have statues or holo paintings that change along with them. Just some starter ideas. I'd love to have this in game real estate to hang out in with my fireteam or friends and possibly clan mates to chill, chat, or plan our next raid in game.
