Thank you roj leather and Simon for your recommendations. I like the hanging chair and the almanda creeper on the wall. This will certainly liven up the patio.

Tsilanko, I would always recommend professional installation where needed. But what I am doing here is suggesting that WHEN you are planning to build or renovate, to consider how your plans will affect you in 20 or 30 years time. Split levels are very hep when you are young. A kitchen 3 steps down at 30 is rarely a problem, but might be a hazard at 60, or, as Marjie1059 suggested, if you break a leg. ... All my parents' homes were terrible for old people. They were forced to move to a bungalow in extreme old sge because the location and design of their home was more suitable for an active young couple with a large family than for an elderly couple with stroke disabilities. I would not want to move again, so my present home has features built in that make ageing in place simpler. Mostly small changes, like grab rails, and lever handles on doors and faucets. A major disability suddenly suffered requires major changes if permanent. I did look at this because it came up in the discussion, but if you look at the heading, Planning for Disability, it means just that. Plan ahead so you don't have to make expensive changes later on. But thank you for your advice, yes, major changes are not in the DIY domain.

Hi Kamal, Greetings, The fact that it is on roof top it can be designed keeping in mind few very important facts mentioned below: 1) The workstations could be organized in a way that every person get a view outside. 2) The outside area can be semi covered so that it can be utilized for some activity space.may be dining, reading area, etc based upon the activity programme. 3) Some kind of alternate ventilation to replace airconditioning or air cooler so that it can be energy efficient. 4) The furniture outside can also be multi functional to make it user friendly and also catering to multiple activities. 5) If the semi covered be made open somehow it can also serve as terrace. The list is endless. Depending upon the plan and requirements it can be designed accordingly.

Dear Mr. Venugopal, Since your space is limited and you want to optimize the walkway as well, some tweaks maybe followed: 1. faux turf/ synthetic moss turf / grass turf 2. Conceal spiral staircase with a pergola and wooden slats 2. Create a cozy corner by installing a gazebo, creepers and couple of swing chairs (30-50 sqft) 4. A small vertical garden alongside the stair room walls. 5. Ambient LED lighting. 6. Stone paved walkway Regards, Aurum Ideas and Spaces Bhubaneswar
