Keeping in mind regarding the Renovation of the House it is a very simple law that any unique but comfortable change is always welcome. When I went to renovate my old house it was looking very difficult that how should I act? But the Internet age helped me a lot. Altavista.com gave me the images of a lots of front elevations. Vaastu site helped me for changing the face of the house very scientifically. Vaastu is not orthodox but a science of ’House making’ with vast knowledge of architecture with thousands of years of experience poured.
As it is important that every person has its own perception of front elevation. So you can do with your idea. Take help from Internet. Every design is there. When you grow with your own idea it will make a unique facelift of the house. Carefully think that your idea of change does not collide with comfort. Comfort is primary thing. Always keep in mind that sun and air should always be in ample.Take care of North side it is mostly damp due to nature of Sun rotaion . So leave ample space in north of the house for excellent air and light ventilation. This point is simply ignored. So take care
Hence I conclude this . But your own idea will be a boon. After all you have to live in.
