Cost of adding an extra floor above my carport.

[scott1999]

Hi all, advice please.

I'm looking at lifting the roof of the carport and adding a floor to give me an extra room, similar to the drawing. Does anyone have an idea of the cost? I don't need walls on the upper level only a railing. Thanks.

Need pix of how the roof is connected, so to see what additional structure is required..  

 

Concert plank flooring cheapest, measure the sq.M size and you can work out much that is. 

 

Dismantling existing roof and adding additional structure required, lay floor and erect railings, replace existing roof you need labour costs, from your chosen builder.

 

Go with an external staircase..

Thanks  Kwasaki for your reply

the length is about 24 feet and the width is about 19 feet. So that would be the size of the concrete floor. And yes a spiral staircase would be nice too!

Looks to me like you'd be better off tearing it down and starting over.

Why? The posts look substantial enough to do the job. It’s not going to be a living space on top, no walls, so not a huge extra weight.

i would think the job could cost under 50k if it’s only above the existing space

How old is the iron? And what iron quality? 

 

How is the iron anchored to the posts?

Thank you for your reply. The villa is 12 years old and the quality? If you go by the way the villa was built, I would have to say; quality is good. As for (Anchored) See photo. Thanks again

Yes, I was quoted 80 Baht A square metre for labour by a local builder. Thank you so much for your advice. It really is helping me.

You could lift the original roof, and made new base and iron below, but then you need to know if its possible, both the structure is strong enough, and you have people who know how to do it. The iron quality is not stainless steel I would say by looking at it but could be wrong. 

 

The steel is not welded in to the steel of the posts? Just grounded by weight? 

 

It might just be better off to build a new one, and it would not cost more than 50k, 

 

here we pay 2000 bath for one posts for the work only, and good insulated roof less than 250,- a m2. Steel Same dimentions you have there in the base, is 800 baht for 6 meter stainless steel. So my best guess is build new.

If it's not going to be a living space, what is it going to be? It looks like a living space in the OP.

I would like to make it a open plan (No walls) Breakfast and chill area (Evening). The views are spectacular from that height. That was the closest drawing I could find for what I want to achieve, but without the walls of course. The step down area on the left of the drawing I am considering a plunge pool area. The Plunge pool being made from concrete, with wood decking. There is already a concrete base there to build on.

Ha ha ha ha, maybe. But really I have 10 doggies, so it would be nice to have one area that they can't beg  for my food. Their food is good enough ha ha ha ha

For 80 baht a square meter?

 

I you are trying to build the cheapest thing possible, use the existing roof and columns.

For 3,840 you can't go far wrong, you just need to know what you want.

Anything you 'add' to this structure and what method you choose is not the main consideration.  The main factor is the load bearing capability of the existing columns ( posts).  Were you around when they cast these and if so can you recall how deep they went.  If not then you are gambling on them being deep enough to carry any extra weight.

 

Without then revealing the foundations my only suggestion would be to use as light weight materials for the 'extension' as possible. Pre cast concrete slabs are very heavy, so my solution would be steel beams and a wooden deck.  Maybe look at reducing some of the weight in the roof to compensate.

Thanks for your input. No, I wasn't around when this villa was built. So I like your advice. Keep it light with wood decking. Thanks again

So you want something like this without the water

or this with railings 

 

on top of the carport + something a little similar beside it

 

one thing I would do is drop the clearance height for the carport as if you leave it as is the whole building is going to be too high

So about $100 or so total labor.

What could go wrong?

Hi,

 

I know I'm way off with the pricing, that is why I asked for help in this forum. Here is some new info, the farm next door to me is having a new barns erected and from my bad Thai and their bad English. With a concrete floor these barns are costing about 20,000 baht each. I think with everyone's help I'm getting a clearer picture of what I want and how much it will cost. Thanks again everyone.

How deep are your foundations on the car port that will depend if you can go up another floor I  would imagine looking at the pictures that you might have to re enforce the foundations
