I think it really depends on the size of the timbers and the connectors you put them together with. The Lover's Key comfort station took a direct hit from Charlie, wind and water at 145-150 MPH and survived but it was framed with 12x12s with 1/4" stainless connectors holding it together on pilings that went down about 20 feet. About 100 feet of the beach was gone but the building stayed. Nobody was around but they suspect the waves went over it. I may be able to find picture I took from my boat, looking up under the building.
