Home Extensions & Additions

If you love your location but need more space, an extension is often the smartest way forward.

Second-Storey Extensions

Second-storey extensions are one of the most popular ways to expand, especially when block size is limited. By building up rather than out, you preserve your garden or outdoor space while dramatically increasing your home’s footprint.

What our clients say about us

We take pride in building lasting relationships with our clients by delivering consistent quality and exceptional results, every time.

Backyard with a swimming pool, glass safety fence, wooden pergola with seating area, and tall wooden fence with greenery.

"We can highly recommend Nathan from Dwyercon as an excellent builder!"

He pays attention to all aspects of the build and takes great pride in his work. Our project was a very challenging build from an old flat roof house to a 9 degree pitched roof with a partial double storey on top. Amazing transformation!

Client

Barbara & Graham Archer

Melbourne

Modern two-story brick house with large windows, a driveway, and lush green shrubs on both sides.

“He was easy to work with and readily contactable whenever we had queries”

The quality of work throughout was excellent, from both Nathan and his subcontractors, and delivered on time and budget. We have no hesitation in recommending Nathan to others, and would be happy to work with him again.

“The worksite remained clean and secure throughout the build”

They refurbed an existing room, added a study and large new master bedroom with walk in robe and ensuite. The process was seamless and we are ecstatic. The build was of high quality/efficient/fast and most importantly on budget. There were no hidden extras and billed as quoted. Workmanship on all secondary trades(electrician, tiler, plasterer, etc...) was impressive.
