Home Additions & Extensions

Home additions are a great way to up size your home without the pain and hassle of searching for a new home and moving your family. If you love your home and don't want to leave it, but you just need more space, an addition could be the perfect way to create more living space without upending your family.


A Dormer is an existing or a modification to a roof structure adding full height ceilings creating additional living space to areas that would have otherwise been a crawlspace or eves. Dormers can be partial, or span the entire second floor. In the case of a Full Raised Ridge Dormer, the existing house ridge is removed and a new one is installed at a higher elevation creating a more pleasing and useful roof pitch.

Mother/Daughter Conversions

Mother / daughter houses differ from a multi-family residence in that multi-family homes have separate entrances for each of the living areas, whereas a mother / daughter is arranged as two separate living areas but is connected as one overall dwelling unit.

Complete Alterations

Sometimes the house you've lived in forever (or maybe recently purchased) needs a lot of work. Styles change, tastes change, families change, people change. Maybe the floor plan that was designed for your house the was built in the '70s just doesn't work well for you. Perhaps your family situation has changed and you don't need as many rooms and would rather open up your home.

We've helped so many others build their dream homes, let us build yours too!

I have worked for a lot of General Contractors over the years, and I can confidently say that I think that you're one of the best. Your staff makes it easy to work for you, by letting me do my job and by giving me all the information I need for that job. You have a great clean-up crew which I also find helpful. You also pay right away for my services. Most companies have no idea what they are doing, but you guys do it right and should get all the work!

Current Subcontractor

Howie (owner) and the team at Great Additions were amazing! Punctual, truthful, honest, answered everyone of my questions and phone calls during the entire process! My dormer and entire house remodel went as planned and also every one of my concerns were addressed and in a punctual manner. All the workers were extremely professional as were Mr. and Mrs. Gumpel (owner). Howie was at the job site everyday which gave me such a sense of security when I couldn't be there. I would highly recommend Great Additions to anybody. I have had nothing but a great experience with Great Additions and have not one bad thing to say.
