Our Portfolio

Loft conversion, mezzanine floors and attic rooms

What are the costs of a loft conversion? Well, it is a lot cheaper than you might think. You can convert your empty roof space into beautiful living quarters at very affordable prices. An attic or loft conversion increases the value of your home, plus there are many more good reasons to convert your attic. Read here what they are. STJ Joinery will help you design and build your new attic at very competitive prices.

Timber Decking in Cape Town

Decks offer many advantages over hard landscaping. In addition to the aesthetic potential for a natural product in your garden, timber decking is a very cost-effective way to extend your home’s outdoor area. Our decks offer outdoor living space and they are an excellent and safe area to play for kids. They make a warm and comfortable surface while creating a seamless transition between house and garden.

Staircases and Balustrades

Balustrade and Staircase

We offer steel and timber staircases and balustrades, or a combination of both. All our staircases are pre-made off site. Balustrades come in a vast selection which includes timber, steel and glass, or a combination of the three. All staircases conform to building regulations and are professionally installed. A staircase installation takes a day or two and can be used within 24 hrs. Staircases should be a feature in any house and complement any room if correctly designed and installed. We offer floating, open and boxed tread staircases and assist you with the design.
