Second Story Addition

Before you can build a second story home addition, there are a few things that need to be taken into consideration; local codes must be reviewed, laws may prohibit the building of second floors because they can create shade issues for neighboring homes, general aesthetics of the area.

Construction Project Management


Greenberg Construction will help you understand whether or not it is allowed to build a second story addition in your zoning. Requirements will usually differ depending on the type of home; for example, a second floor on a ranch style structure will create much more stress on the footings and foundation than some other styles of building. Because of this, footings and foundations are usually built much stronger and wider for two story buildings and some foundation work might need to be done before the addition can begin.

Keep in mind that second story additions are always a little bit more expensive than a first floor addition due to additional reinforcements that are needed to be done and permits which must be attained.

Master Suite Addition / Master Bedroom Addition

Bedroom additions normally involve a large number of design factors. Building a master bedroom suite includes extra planning, because plumbing might be needed in order to add fixtures such as sinks, shower, bathtub and toilet. These fixtures may increase the value of the addition dramatically, especially if fixtures such as a spa tub or a custom shower are included. These fixtures will also increase the value of your home, so more often than not it is a worthy investment.

Kitchen Addition/ Bathroom Addition

When building a kitchen / bathroom addition, we will review your existing home’s plans to make sure that nothing will impede the kitchen / bathroom addition’s construction. Checking items such as the location of underground utilities, the drainage easements, septic tank and leach field if there is one. Although in some cases it is possible to move existing pipes, the location of all these items could impact the addition.

Guest Cottage Addition, Guest House Addition, In-Law Suite Addition

There are so many reasons that adding a fully contained living space to your property might make sense. It could be that an older member of your family may need a place to stay. Maybe you have houseguests that stay just a little bit too long? Twenty something “child” that isn’t ready to leave the nest? Or maybe it’s just an opportunity to rent the unit and make some extra money.

Building a home extension for the purpose of adding a family room is a great way to increase both the value and functionality of any home, a family room when designed correctly, can be the focal point of a home, it is a space where anything goes allowing flexibility unlike any other type of home addition.
