example: winding staircase, source internet Little modification need to be done for entrance lobby opening, where you could accommodate a shoe rack and the complementary vertical wall can act as a amazing entrance decor wall wall in Kerala style heavy color play or texture/wall cladding with brass mural.. by doing this you get space to mount TV unit and a good space for sofa arrangement (make sure sofas are light as the space is less to accommodate baggy sofas), staircase can be made in the shape shown in sketch plan, with marble finish on the foot steps (or as per interiors), space in the bottom of staircase next to master bedroom wall can be utilized for chest of drawers or a tall furniture, make sure the staircase bottom part to be casted smooth in finish.

Hi Indrani, Go for matte finish tile. Here are few reference images. -Thanks, -Neelam -Lines and Profile

Hi Ashish, You can opt for any of the following options - 1] Frame the L- shaped junction of the wall and beam/ceiling with a wooden frame similar to your handrail and fix glass into it as shown in the image below. 2] Alternatively, you can go for other options like a jali or rafters to secure the opening and complete the look. Like this - Doing this would provide an enclosure to the staircase and give you some storage space below the landing as shown below. Conceal the space with a veneer finished door and a handle and you are good to go. You may store hardware items, gas cylinder, gardening equipment etc. or convert it into a wine cellar if you like. All the best! Regards, RnD Atelier Nagpur

Just leave it as it is apply a layer of matte varnish over the concrete ...if needed just add a plank of leather finished granite over the tread
