Home Addition Design & Construction

When you’ve created special memories in your home, leaving it behind and moving is difficult. But sometimes, you outgrow it and need more space. Rather than purchasing a new home, turn to SEI Construction, Inc for your Central New Jersey home addition. We’ll add living space to your home’s exterior that will not only look and function great but will blend architecturally with your existing structure.

Whether you want that family room for all to enjoy, extra bedroom, home office for your business, sun room or something more; we’ll meet with you, discuss your visions, wants, needs and ideas to create a tailored plan of action for your home addition.

If you’re concerned you can’t add a Union County home addition because your property lacks the square footage, SEI Construction, Inc has you covered. We can build up and add an entire new story to your home without taking up any more space on your property.
