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 a structural element of a building that protrudes from the plane of a sloping roof surface. Generally they are used to create usable space in the roof of a home and they enable the addition of windows into the roof. Frequently, dormers are installed during a remodel as a way to create more space while attempting to make better use of the space available in the existing structure. They're also used to add a great look to the exterior of your home.

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, lets us build yours too!

We were very happy with Great Additions. Howie is a pleasure to work with and extremely professional. They use the best materials. The subcontractors are all reliable and easy to work with. They all work with you to get what you want. It went as well as a major construction job could possibly go. Any time we noticed something didn't look right or something didn't get done, we contacted Great Additions and they fixed or took care of it right away. Most importantly, THEY GET THE JOB DONE. They don't keep you waiting around forever for the finishing touches like many contractors do. If we were looking to build a third floor, we'd hire them again. But Hempstead probably won't let us do that.

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 manor. 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.
