Older buildings often started life as a major depression called a basement. This area may have spent years being neglected. Going down those stairs might have been a dare for the kids, but their parents might have decided it was best to leave things alone. The cavernous underground space might be filled with cobwebs, ancient furniture ready to fall apart, or it could be a place where there is additional room to add onto the house without expanding into the yard. Upgrading the basement has many good points, and modern construction methods can make it a bonus for the whole family.
The majority of older houses with basements sit on top of a very deep foundation. The building costs might have made it a good idea, or the land beneath the house might have needed deeper support to keep the house from settling. Checking the foundation when considering a basement upgrade is a good first step. Many people may be surprised to find their foundation is still in great shape.
One of the issues with basements has often been the musty smell. This can occur due to a lack of water barriers, and many modern regulations require one to be installed. It may sound like a very difficult and expensive job, but that is not necessarily true. The need for a water barrier might be covered with nothing more than a plastic liner on the floor and walls. It can then be covered with new flooring or walls without the need to replace anything else.
It can be quite expensive to add on to an existing home, and taking up yard space may devalue a property. Using the basement for an upgrade provides additional space without taking away from the rest of the property. It may be the most efficient option in terms of money. Building amenities into the basement may also be easier due to the fact an older home may have plenty of height in that area. New ceilings can be put in over plumbing and electrical.
