Second storey addition
 

Guys wondering if any one has any knowledge in this field.

Wanting to convert single storey to two storey house. Is this a cheaper proposition than knocking it down and starting from scratch?

Is there a different foundation made for single Vs twin storey?

House was built in 1991 so Fairly solid construction all brick.

Thoughts woukd be appreciated.

Are you talking something like just one extra bedroom on top of your existing house? Or are you looking at adding afew bedrooms/gamesroom etc?

Building a complete second storey rooms and bathrooms etc

pick up your e85 barrel from my work (we are civil engineers)

we can chat.

Will the 2nd storey be suspended concrete slab and brick or framed floor & walls?

It's cheaper to build second storey on top of existing bearing in mind it is usually constructed from timber frame and cladded then rendered/finished to your taste etc. What I have been told the cost blowouts tend to occur with the level of finish you want internally ie -bathrooms/wet areas can be finished modestly or they can get hugely expensive - tiling and plumbing.
We were quoted $120-150k a few years back to do this, similar to your idea of a couple of large rooms and a bathroom/wc.

You will also lose a large chunk of space somewhere in your bottom story to allow for the stairwell and landings.

We were given no indication of foundations being an issue it was the roof structure we were told is the focus of the structural engineering.

You also need to factor in the exterior finish of the top story needs to match the bottom so you may need to render/paint bottom story...

Tristan if you could make use of that barrel that would be great?

Fred i would prefer slab and brick over timber framing etc.

This is only a hypothesis just asking some questions for the future. ha

If you want a suspended slab it will be a compromise whatever you do and the costs get out of control very quickly.

Imho knock the thing over and start again.

Hmm any benefits of suspended slab and brick over floating floor and cladding? Apart from noise insulation?

suspended slab = knock over & start again

more to it than just the footing size, unless verticore bricks were used in the single story construction it will be a nightmare, most single story of that vintage used horizontally cored brickwork for internal walls rendering them useless as loadbearing elements

light weight stud work = do-able but cheap, house will always be considered as a 'loft conversion',insulating, heating & cooling of said addition will always be costly
