Hey, architectural designer here. You might get some more help if you provide a little bit more info. Things that would be helpful to know include general square footage of the space, how much are you looking to redesign (ie. just looking for paint options, or new furniture, new carpet, new floor, etc..) this is essentially what is considered the “scope” of the design. Pinterest and Google images are your friend! You can go on there for inspiration and can help you find products so you can start setting a budget and vision. Hope this helps and good luck!
