Can anyone suggest a good contractor to build out the 3rd floor.

I currently live in a 2 floor house in a housing estate. I would like to remove roof and build up a floor and reroof the house. Its a concrete house and i plan on using galvanised Studs and Drywall on inside and Concrete Smart board on outside with insulation inbetween. This should keep weight load down on the pillars of the house.

Why do people here who ask for recommendations always fail to state where they are located

Should we recommend a Bangkok contractor if you want the work done in Korat

Your first step will be engaging an engineer to review your existing plans, your proposed extensions, and asses whether or not it's technically feasible and will also pass tessaban approval....

Even with lightweight walls, it still needs beams to support them, and it still needs a floor, and most tessaban's want to see floor designed to be able to cope with a minimum of 200kg/sqm of weight - i.e. even if it's just 50sqm, it'll need to be designed to support 10 metric tons, with a Thai engineer signing off on it..

The rules vary based on zoning and region. But in short, It's not about what you're going to put up there, it's about meeting a minimum standard so that subsequent tenants also have a safe building.

No, his first step will be telling us where

Even you state:

The rules vary based on zoning and region

Got a mate in Wales that does loft conversions. PM if interested in his contact details

would that be in straw

Sorry guys, i assumed you should be able to see it in my profile. but anyways, I am in Nonthaburi. Right next to the Nonthaburi City Hall on Ratanathibet road.

I have just had my pillars reinforced for more weight using a metal and concrete.A guy dug under my house to use hydroloics to push down a metal pipe in 1 meter increments, and he kept adding more increments till we hit hard rock underneath the soil. Now my house pillars shoot down pretty darn deep. Some as deep as 60 meters. I can handle the weight of the addition but i really would like a nice builder that knows what the hell he's doing...i have seen so many shitty contractors that dont know how to do anything correctly.

Just wanted something simple with lightweight bricks, and galvanized studs and sprayed in insulation on the walls and wood/concrete hybrid siding so it does not get so damm hot....and properly grounded AC,,

Thanks

Oh yeah, so after all pillars we finished we poured concrete inside the metal tube to make it more stronger.

about 24 pillars under my house...

60 meters!!!????. In the Bangkok area you start hitting bedrock/super compacted soil at around 17-21 meters....and that is the length of concrete piles used for new homes in the Bangkok/Nonthaburi area. You sure your hole driller wasn't pulling your leg?

i am dead sure, I counted and watched as they did it. If i remember correctly we had about 4 or so that went down that deep others were in the 30-40M deep.

Well I had a great contractor for you he builds to almost U.S. standards & most of the time in structural German standards , but he bases out of Pattaya & I think it would be to far a stretch in that area sorry. But you really should review if your building will support another floor even if it looks kosher you wouldn't want to find out that it isn't later as other posters pointed out.
