DOUBLE-STORY EXTENSION & RENOVATION

Mt Martha

A double-storey extension on a challenging site, we thoughtfully transformed this existing 1950s beach cottage into a modernised, open-plan family home. Featuring burnished concrete slab, recycled brick walls and Terrazzo tiled bathrooms, our team both maintained the heritage of the home’s exterior while crafting a more practical internal layout designed with practicality in mind.

EXTENSION & RENOVATION

Mt Martha

Connecting new and old, our team crafted a new façade and entry for this classic 70s-era single-storey home. Featuring an entire internal renovation and a modernised extension (front and rear), we tastefully altered this home to give it a modern, sleek twist.

KNOCK-DOWN & RE-BUILD

Mt Martha

Sometimes starting from scratch is the most practical route – so that’s exactly what we did for this Mt Martha home. Featuring an all-new, practical layout, open-plan living perfect for hosting, and a separate wing for the little ones, this complete knock-down and re-build allowed our team to develop a light-filled family home with all the bells and whistles.

"Renovating our bathroom and ensuite with Daniel of Built Onspec was a great experience. He was an excellent communicator and complete professional from the quote all the way to the end product, which we absolutely loved. He took great care and interest in our project and chose excellent tradies that were friendly, efficient and kept the site clean and neat. We highly recommend Built Onspec for any project."

From start to finish, the entire experience was exceptional, and they delivered outstanding results. First and foremost, Built Onspec displayed exceptional professionalism throughout the project. They took the time to understand my vision and preferences for both bathrooms, providing valuable insights and suggestions to enhance the design while keeping my budget in mind.
