With your original pictures - I agree with larger rug. But I don't agree with comments suggesting the rooms are monochromatic. They are lively indeed. I think you are just missing some accessories! Art work on the empty walls - even just a single large dramatic piece is in order. In the bedroom on the white wall, in the living space behind the sofa, in the greenish bedroom behind the two beds. Those are instant areas where you can improve. But I think your spaces are lovely and well put together. Also I agree with the comment about table lamps - some of those would really add something, and your coffee table looks so empty - maybe just one gorgeous bowl, or stack some books. These rooms are 90% done in my opinions, just need a few finishing touches. Some of my rooms come out like this because the clients are not willing to pay for those last few finish items or feel they can do that part themselves...

There is contrast between the traditional furniture and the focal point of the floor which pops, draws attention. I would recover the sofas in cream colored soft fabric - suede. I would leave the curtains grey, and put down a large neutral area rug. The edges of the room would show the pattern of the floor. I would color the wall and add texture to it, but not too dark as the room will appear smaller. Add a picture and put a nice plant holder, large vase in the left corner of the room - an oriental-style vase. Or, a cream-stripe fabric on the sofas. You could go soft or bold in this room - depending on your taste.

I think a comfortable distance between the island and the counter is around 42". It seems that you have only 30" between your cook top and the counter. I might be a little too tight. The wall between the entrance and the kitchen could be 4' long instead of 6', you would then be able to move the island a foot which would give you more room between the cook top and the island. Could you switch the location of the toilet and vanity in your dad's bathroom so your enter facing a vanity instead of a toilet which is a lot nicer.

This is a great space to work with. Since you have a good length, you can break the terrace into rooms.. with yew to divide the areas, or tall plants with shallow roots. Grow grass in curves and a pathway to lead visitors through the various rooms. Couple of ideas for garden 'rooms': Bamboo with golden stem or black stem as background, with charpai and 'moda' seating with cushions. A light under the foot of the bamboo, looking up will be alluring. Put up a trellis with fragrant climbers like jasmine and seating underneath on a part of the terrace which gets shade in the evening so you and your friends and family can relax. A dry garden with hardy plants like tall grass and Palm tree, pebbles on the ground to create the look. Plant a small flowering tree in one 'room' Add evocative lighting to create the mood in the evenings. As you can see there are many possibilities. Please ensure the ground is well protected from water seepage etc before you start planting. Also ensure the height of the periphery wall is taller for it to be safe for children and adults. Bear in mind the size of the plant, roots, sun and water needs before you choose your plants. Enjoy the creation..!
