Face it - gravity sucks. Your house was designed to be supported by the "poles" or are they stumps? You will need to carefully assess the value in removing them all. First you will need to engage a structural engineer to advise you, and he may suggest long steel beams that run across from one side of the house to the opposite side allowing the supports to be removed. However the financial cost in installing these long beams (and additional structure to support the beam ends) will be significant - there is no cheap fix. Once you have paid tens of thousands of dollars (maybe more depending on the length of the spans and ease of access under your house for installing them) you will have a large, open, low-ceilinged space with the proportions and feel of a shopping centre carpark. The structural engineer will need deep steel beams depending on the span between the walls, and this will reduce the clearance under the beams to much less than your current 2.1 metres.

Save your money and engage a clever designer to find a clever solution that works with keeping the supports, and you will get much better value for your spend.

Best of luck with your considerations,

looks like a perfect place for an indoor outdoor living area what's the size of the whole space and the position of the posts?.. i would treat it just like a standard alfresco area but keep the closed in one bay for a storage, mancave, hobby, garden, workroom space and live with the other posts in the double bay and, unless the sliding door is no longer fit for purpose keep it for closing off the open bay for security when you're away and i would like a sink and barbq and maybe consider a dramatic colour scheme and some good timber furniture and potted plants

Hi there, how do you access this space?, It could make a great indoor out door entertaining space. Spray paint the concrete ceiling and all walls except the brick. Timber in the posts. I'd use track lighting for the lights only needs one connection and you can do a whole lot of lighting and at a reduced cost. How many bedrooms do you have and how many family members and ages of children cheers

Have you though to jack and prop up the existing first floor over the existing ground floor to achieve a minimum 2.4m high habital room height instead of adding another level above your first floor?

Although bold in concept, it’s relitively easy to do are fairly cost effective.

These type of homes lend themselves well with this type of renovation.
