Build our A frame house J&J

Hi we live in Zambia, central Africa, and we are looking at building a medium simple A frame house for us. It will be a basic A frame with tin roof sheet and the polystyrene foam as insulation and we will let it visible. We want to use industrial steel beams for the frame structure and also let it expose. concrete slab, and just polish concrete type unpainted as finish floor. 1st floor , whichever floor materiel that will be within our budget. We have a small budget, and we just want a beautiful simple house that we can slowly make it perfect with years. We can slowly try furnish with time but we have a good idea of how we would like it. There will be an up floor where main bedroom all open aswell, small walk in closet simple on each side and as you come up the stairs, small lounge area ( can possibly turn into a baby room in the future ), small created wall where the bed face it and behind it will be the sinks and bathroom ( bath tub style one side and shower on the other side, bathroom facing the balcony. I am looking at an opening door on the Left side of the house looking from the main A frame opening, where car park and small path can be made and accessible to the kitchen area straight away, A normal steel beam straight forward with wooden steps to go upstairs . bathroom will be and on the ground a big loft aswell with 2 bedrooms towards the back, one ensuite bathroom and a guest toilet. Open lounge , small corner bar area ( pool table possibly ) and open kitchen with a kitchen island that we intend to create ourself slowly. We are planning to use the small red bricks instead of normal blocks as its our preferences, that will be for the bedroom walls and laundry / open pantry type etc the front A frame opening will mostly be full glass with only bottom part with sliding door, onto a deck. with a triangle shape swimming pool along the side on the deck. the back A frame will be a small door and a balcony for the top floor . I have a few little pictures drawn and i can chat more to you for sure with some personal drawings. We looking at 10 meters wide and 18 meters length with a height of about 6-8 meters total. We will try use pallets , wooden crates , steel pipes as shelfs, furnitures etc ...
