kensisaket Posted June 2, 2020 Share Posted June 2, 2020 Depending where you live (city vs rural) there are permits needed to add another floor to an existing structure. Suggest you run your idea by an architect/builder before you commit money to materials. Link to comment Share on other sites More sharing options...

RichCor Posted June 2, 2020 Share Posted June 2, 2020 My suggestion would be to try and save the roofing materials, if they're not too sun damaged, then knock down and rebuild so the structure will be built to carry designed weight and shear force on the columns. 1 Link to comment Share on other sites More sharing options...

The Plunge pool being made from concrete, with wood decking. There is already a concrete base there to build on. 4 hours ago, scott1999 said: 5 hours ago, andygrr said: Is it just a concrete slab or is it properly reinforced with rebar. I don't know. But I'm hoping the decking and the plunge pool won't be too heavy for the concrete. If the 'decking' is any way elevated above the concrete pad then the weight of the deck, plunge pool, and water will be concentrated on the support posts an not distributed across the concrete pad surface -- unless you take that into account and add additional supports under the structure. 1 Link to comment Share on other sites More sharing options...

I'm guessing the "pool" will sit on the slab, and the deck would be supported by the columns. 1 Link to comment Share on other sites More sharing options...

It would make little sense (IMO) to try and build the deck to support the pool at that height. The pool in the photo looks to weigh about 5,000kg in water alone... 3 Link to comment Share on other sites More sharing options...

That was my assumption as well and why I said 11 hours ago, sometimewoodworker said: The decking will not, the pool may. Meaning the decking at the high level will not be a problem for the existing supports, however the current concrete pad may not be strong enough to support the weight of a pool, it’s almost certainly thin and may have little or no reinforcement in it my approach would be to build on the posts but dig up the slab beside the carport and put down a slab that reinforced, or you could treat the existing slab as the ground and put a new slab onto it.

Were it *me I would just reinforce the pool, including the bottom. Assuming he wants to use the existing columns, I think it would be better to pour stubs next to the existing to support the deck. *But then again, I would likely demo what was there and start over...

IMO your are correct about the concrete pad not being strong enough. Weight is important of course. Thank you everyone for your advice on these matters. Only today I have found some more photos which mirror what I am hoping to achieve. My plain is to still have the ground floor as the carport and to have the pool to the left of the main structure. But I like the design of this a lot. Looks like on picture one you can see a concrete floor for the the upper level and picture 3 has a nice wooden finish. Thanks a lot to everyone I'm really learning a lot from all of your comments. Link to comment Share on other sites More sharing options...
Puwa Posted June 3, 2020 Share Posted June 3, 2020 Just by way of reference, we built this carport a few years ago. When I told the contractor, who is a structural engineer by training, that someday we would be adding a room on top, he put in a double-reinforced concrete floor (two layers of rebar grid). And we used poured pillars rather than prefab. 1 Link to comment Share on other sites More sharing options...

At the moment I'm into minds. 1: To try and do it as cheap as possible, Using the existing columns and roof and thickness of the concrete floors. 2: Dismantling the roof, digging up the concrete, and starting from scratch. At the moment I'm leaning towards, starting from scratch. Very similar to what you have done, In preparation of building your room. But price will be contributing factor. So thanks again for everyone who's giving me advice. I really appreciate it! Link to comment Share on other sites More sharing options...
scott1999 Posted June 3, 2020 Author Share Posted June 3, 2020 The concrete pad for the carport seems to be one whole section. Then they poured around it, and it isn't very think. Link to comment Share on other sites More sharing options...
