My cousin just recently built their new house which is not far from us. It is not yet finished but they have already moved in as the water and electricity service have been installed. My cousin got married few years back and they lived with his wife's parents at first before renting an apartment. They were trying to save as much money as they could while living with the parents, and then renting was financially draining, so they decided to go ahead and have their home built. They will complete it as the money is available to them.
Since my cousin is in training to be an architect he was able to draw up their house floor plan making sure that it was designed in the way they wanted and with the space his growing family would need. His supervisor finalized the plans and then the house was built. Building a home can be exciting, but as my cousin found it can also be time consuming with all the planning that needs to be done. Usually you have an idea in your mind on how you want your house to look and you share that with an architect who then draws up the home plans according to your ideas and also according to building requirements and specifications.
