Check with your local brick supplier. Most of them sell a thin brick that goes on just like tile (just use a tile mastic adhesive). It doesn't make near the mess as using using full size brick so it works well in existing spaces. A word of caution: The brick tiles do cost significantly more than full size bricks. Here is a pic of a similar product and some pictures from a basement we just completed that used the tile brick as a fireplace surround and an accent wall in the kitchenette.

On the floor. These are vitrified tiles in timber teak digital print. I want to use them in the rooms and kitchen. My dilemma is, whether I can use same in kitchen or I should used another design for kitchen.

I would prefer natural stone cladding instead of exposed brick decor. This is simply because natural stone cladding can provide a classy and elegant appeal to the home. Also, it is easy to maintain and lasts long. Another reason I would prefer stone cladding is that it provides a modern touch to the interiors. I would also prefer patterned tiles or textured walls over exposed brick as I feel that it makes a space look more lively and beautiful.

Thanks for clarifying Mentes. Before answering let me clarify that building materials should better be selected based on local advice, availability, cost, structural requirements. Your architect would be giving you an informed opinion based on that. Cement Bricks have more strength and are cheaper than the red bricks. They also help to complete the work faster because of bigger and uniform sizes. So, I would prefer to disagree with the reasoning given. Secondly, you are in Kerala and fyki, red bricks takes away precious farming soil layer away. We already had a bad flood. In the best interests of nature you may want to avoid doing more harm. To be fair to red bricks, they look amazingly beautiful and are good for load bearing walls, last long and are better for thermal insulation. Thanks, Nitin Cornerstone Designs Studio, Bangalore.
