This is a sit out overlooking the drawing room in my garden apartment in a condo. Need ideas to make it look like an outdoor living space with sufficient greenery around

If you could post pictures that would help, also make sure of your building's codes/rules, keep in mind weight, drainage, exposure (sun/wind/light), privacy concerns, lighting, etc. and consider getting professional design help for someone who specializes in roof gardens. You don't have to do everything all at once but a design professional could help you clarify your vision and give you ideas you may not have even thought to incorporate. Best of luck, 800 sf of outdoor space is wonderful. Don't forget you've got to get everything up to this space too.

An uninspiring view of building next door was camaflouged with the help of lot of indoor plants -big and small in beautiful planters and other accessories. Stained glass birds sitting on a branch, colourfull bottles and metal butterflie fixed on glass panes made this sitout area very inviting.

Shubham, Are you opening a tile and marble shop ? Well you would know the materials then ;) These are called garden paving stones . And a 'Sadarahalli Grey' machine cut will be a close match to the pic shared. Stones are often named differently in different geo's. It's called sadrahalli in Bangalore region. thanks, Nitin Cornerstone Designs. Bangalore.
