Building outside living area

[Mike45]

I'd Like to have a large outside living area attached to the back side of my house.

Its needs 74 square meters of concrete with 20 cm posts. Three meters high at lowest end. The roof is to be matching CPAC monier tiles with a radiation barrier, steel structure and a finished ceiling with a couple of lights.

I have no idea how to price this out. Its in issan.

Will the floor be a ground slab, or a suspended slab on top of beams?

Will it have walls, doors or windows?

Will the floor be screeded cement, tiles, stamped concrete, sandwash or something else?

Will it need drainage?

Where the roof meets your main house, will it be able to butt-up to a wall (e.g. 2 storey house), or does the existing house roof need to be modified and merged into with the new one?

If the OP wants walls, doors, windows with sandwash floors and a suspended slab, that's a proper extension to their existing house, they can budget 10-12K sqm. A basic sala style construction with ground slab, precast posts and just a roof/ceiling might be able to be done for as little as 5-6K sqm though.

I should have included more info. Sorry.

Ground slab

No walls doors or windows

Tiled floor included

Drainage? Like a gutter? It wasn't mentioned..

Will butt up against rear of two story building. No roof modification necessary. The new roof will only reach approximately half way up the wall.

If using a ground slab, no floor drainage required, precast posts with steel trusses and CPAC tiles, I'd expect around 5-6K per sqm should be achievable for the basic structure - if you buy the materials yourself, and pay workers for labor only (and you buy at the right prices!).

The tile floor is variable - tiles can range from < 100 baht/sqm up to 2000 Baht/sqm or more for high quality marble or granito. Being semi-outdoors, a textured tile would probably be what you want though (non-slip) so you could budget around 250-450 sqm including laying.

Other expenses not included in the sqm price range are:

* Decorative trims (i.e. you might want to fit trims around the post to match the trims on your house if applicable)

* Specialty finishes on the posts (i.e. you may wish to tile or brick around them)

* Painting (posts, soffits, ceiling etc)

* Electrical (lights, fans, switches, plugs, wiring and dedicated load center or additional new breaker)

* Railings (just trying to imagine what you may wish to add in )

* Ceiling, Soffits and Cornices (if/as req'd)

* Rain gutters

There is a big range of variability in all of these, so up to you
