Pay attention to your HVAC system
Poor planning with this can lead to issues with moisture and mold growth. This can then lead to great health concerns. Careful attention should also be paid to the size of the units. A model that is too small will underperform and won’t effectively cool and heat your home. You’ll regret this when your home is too cold in the winter and not cool enough in the summer. Units that are too large will use too much energy.Poor space planning
Unless you are going to build a very large home, planning the space is crucial. You need plenty of storage and need to think about where you put this storage. Does the master bedroom need that huge walk-in closer when that space could be better used in the master bath? Pay attention to where you put the closets. There should be one in each bedroom and in the main hallway. However, too many closets will take away from the living space. If you live in a cooler climate where you’re wearing coats for at least half of the year, a closet in the foyer could be wise, especially if you often have guests over. If you have no use for a cost closet, don’t build one. Do you want a mudroom? A closet or cubbies would be very useful storage.
