Nicholson Parade – Home Renovation & Extension

We recently completed a full renovation and extension for an exceptional client in Cronulla. The project took 4 months and included the entire inside of the home being redone. It also included the extension of the back of the house, incorporating a large back veranda and pergola with a 6m high roof!

The building process was quite straightforward. Firstly, we gutted the entire exisiting structure. Up next, we added an extension on the front of the home to create a relaxing sunroom as per our clients brief. Once this was complete, we extended the back of the home by raising the ceiling and bringing the roof line out further. This allowed us to create the large pergola and outdoor living area that was a primary requirement from the client.

At Hyspec Constructions we experienced builders and always tackle any challenge head on. With this project, the main challenge was lifting the large timber beams into place to create the huge 6m tall pergola at the back of the house! The property has limited narrow block space which made this process a little tricky but as always we got the job done right first go.

This project was a fun one that came up great! We really enjoyed transforming this old home into a vibrant new one with a beachy vibe to suit the local Cronulla scene.

Como – Home Renovation 

We recently completed this structural redesign and home renovation in Como. This southern Sydney project took us 1 month to complete and finished up giving the family the free flowing spacious feel they were after!

We kicked off the building process by removing the load baring walls. This project required the installation of brand new steel structural beams and posts to new concrete footings. This allowed us to remove old walls, create the new kitchen and extend the flooring area.

With any building project challenges arise. For this home renovation, the main challenge required us to carefully install the new structural posts in through the floor without damaging the existing floor area.

The client was very pleased with the end result and said “We engaged Brett from Hyspec Constructions for our renovations. Brett and his team were excellent from quote to completion. As novice renovators we also asked Brett to organise the plumber and electrician, they were great to deal with as well. I’ve already started recommending Hyspec Constructions to my friends.”

Engadine – Home Extension

We recently completed a home extension in Engadine. As Sutherland Shire builders, we have completed a wide range of projects in the area. This home extension project took us 2 months and resulted in the clients having the extra family space they needed!

Being based in a BAL-FZ zone, this required us to use specific building materials to ensure the best fire resistance possible. The original brief from the client required us to extend the back of the house by 4m and add an additional back deck. Besides this, we were also required to create a new lounge/dining room and build in a new staircase.

We used special modwood when building the deck, glass balustrade, and modern cladding all inline with Australian requirements for BAL-FZ zones. One of the defining features of the home extension was a massive glass sliding door that spans nearly the entire house. This really allowed for a free flowing wide spacious outdoor veranda feel from the inside of the home.

A specific requirement from the client was that they didn’t want to interrupt the view from the property of the lovely surrounding bush lands. We accomplished this by using no posts or beams for the eve which creates a clean sophisticated look.

  • positive review  These guys went above & beyond their duty when constructing our deck. They faced numerous obstacles due to the nature of the old existing deck, and throughout the entire process they were professional, thorough, neat & tidy, and their attention to detail was of the highest standard. We will always highly recommend the team from Hyspec Constructions 😊

  • positive review  Hyspec Constructions & Roofing completely transformed our 1950’s fibre house to a modern and contemporary clad home. The advice and workmanship from Brett, Luke and the team was second to none. Many people have commented that we got it ‘just right’ and this is no small part to Hyspec. Thanks boys, we are so happy with the end result.

  • 5 star review  We made the best decision to get Hyspec to build our 2 decks and 2 pergolas and an amazing feature stairs to lead us from one deck to the other. Brett, Luke and their team of skilled tradesmen were a delight to have around. From our first meeting I felt at ease with Brett and his vast building knowledge and creative ideas to help us plan our dream backyard. The boys worked with great skill, passion for detail and care to see the job was done right the first time. Brett was flexible, always willing to listen and also ready to suggest any alterations to the plans which would improve the end result as the project progressed. His team were great guys who took pride in their work and always left the site clean at the end of each day. If you are looking for a great local builder in the shire I would recommend Hyspec construction and roofing highly. Thanks Brett, Luke and the Hyspec team, we love our new decks and spa pergolas.

  • 5 star review  Brett and the boys put up a privacy screen along my deck. Right from the start I got honest advice and, most importantly, the job done when he said he was going to do it and completed on time with a quality finish. The finish is beyond what I expected, all waste materials were neatly cleaned up leaving me to kick back with a cold one and enjoy their hard work. Cheers guys.
