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...

It is always much more interesting to buy pieces rather than a set. A painted dresser would be great to change the boredom of too much matching. Lamps on each side of the bed do not have to match either. You can repeat a common element ie. shape or glass base but different shades. Don't be bound by rules. Buy what you like so it is an expression of you.

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..!

Actually the plan ( in black background), the one with measurement is the original one drawn by an architect . The other drawing (3d n the colourfull) is just a plan i drew to have an idea , where to arrange the furniture nd some modifications using a software called MAGICPLAN. That is why the staircase and bed is of awkward sizes, my bad. About the modifications, i have removed the partition between living and dining, have made a space for handwash, storage spaces for one bedroom and in kitchen which is protruding outwards marked with slanting lines in drawing, also extended 60 cm on northern side of the house to make room for balcony for bedroom, more room for bathroom nd work area. Do u think there is less space for storage, like to fit in an godreg alamarah somewhere??
