Dear experts and all,
i have a small 5 marla double story house on load barring structure and now i am planning to build a studio on the top which will be around 450sf ( one room 26x13 kitchen 8x6 and bath 8x6 ) now due to load barring structure i am planning to reduce the load as maximum as possible my question is that apart from concrete roof do i have any other options to minimize load and budget , kindly advise my house is in rawalpindi city ( both hot and cold weathers are extreme !! Many thanks
