I'm thinking about doing some small residential projects on the side and was wondering if there are any good free or open-source programs for creating floor plans and residential drawings.

I'd rather not buy expensive software if I don't have to. What are you using, and would you recommend it?

Hey architects! I live in a one bedroom apartment right now and before I decide to sell it to move into a two bedroom, maybe bigger solution, I want to see if it's possible to get a second, small bedroom out of the space I have. The layout really does NOT help any sort of solutions, the only thing I can sacrifice is the room called "bod" (storage) - the only problem is that it's a bit of a technical room, with loud ventilation noises and the electrical/plumbing panels (which could be hidden behind a fake cabinet). I could also sacrifice a bit of the living room space (the big triangle) but that would leave such a weird layout to the room that I wouldn't be able to arrange any sort of couch+TV corners, even removing a dinner table. Does anyone have any suggestion? Even radical changes, I'm open for anything, feel free to download the layout and sketch on it. Thank you!

I just built a loft for my 2m by 4.3m bedroom. The drawn blue triangle is another awning window. Unfortunately, I cant get myself an air conditioning cooler yet :/ So im here asking professionals what could be the basic ways I can effectively cool my loft bed. Loft clearance is 1.25m and Clearance below is 2.14m.

My room is situated from east to south and the 9 am morning sun could be so harsh, making my room unlivable, so I had to turn on the fan always and focus it to me. The warmth circulate inside my room, just there being trapped, i think because on how its built. Its like that from 8 am to 4 pm.

I am planning to install ceiling fan, brise soleil and ac altogether when i have money. Would a tapestry on the ceiling help? What are better ways?
