There are many different ways to do this and if the 4 partners are of similar networth then I imagine all their accountants will have a similar ownership vehicle in mind. Also depends which country you are. Be careful giving any 1 partner too much power as I have seen that backfire often. Step one work with the accountants, step 2 work with 1 lawyer taking feedback from partners and accountants, step 3 each partner should have their own lawyers go over the structure to make sure one power can't borrow against the property in the future without certain checks & balances etc...
