Limestone gives Sandstone a run for its Money

showcase-grand-13Sandstone has long been the building material of choice for some of the most beautiful and prestigious homes in Sydney, but now there’s a new kid on the block.

A number of Sydney architects and builders are starting to recommend limestone as the building material of choice for their clients. These early adopters are crossing the border and sourcing their limestone from our quarry near Mt Gambier in the South East of SA. And for good reason.

Limestone colour range

Bruhn Limestone is a beautiful natural resource. It comes in a variety of colours ranging from light creams to rich biscuit hues which offer you different options for your new home.

Because Bruhn Limestone is so easy to work, it allows us to create a wide range of products such as face-finished ashlar blocks, solid decorative moulds and an assortment of columns.

A quarter of the cost of sandstone

Limestone is about a quarter of the cost of sandstone, which represents a significant saving — funds that can then be redirected to other areas.

Craig Anderson from CA Building Services in Sydney said,

“One of our clients really wanted sandstone for their new home but their budget just didn’t allow for it. We thought limestone was the perfect solution. Our clients were excited when we told them we could create the look they wanted with limestone, at a fraction of the cost. Even with the transport costs from SA, building with limestone represented a massive saving and still allowed us to create their ideal home.”

Building a new home is a big investment and with so many costs involved, finding a way to save money yet not compromise on quality or style is a huge bonus. Savings on the building material will mean more money for those beautiful fixtures and fittings on your wishlist.

And when you see what a beautiful backdrop limestone makes to your stunning new interiors, you’ll be extremely pleased with your choice for many years to come.

Upgrade your building material to limestone

Because limestone is such an affordable building material, many home owners who would normally be looking at building in brick and render are also discovering limestone. A new home built in limestone will cost about the same as brick and render, but you’ll get a lot of extra benefits such as high thermal and acoustic qualities.

Limestone is versatile

Limestone is a material that works equally well for traditional or modern designs. Which means that no matter what your dream home looks like, we think we can help you achieve it. And it doesn’t matter where in Australia you’re building either — we supply our limestone directly to your site, anywhere in the country.

Sandstone Blocks

About Limestone and Sandstone Blocks

  • Limestone and Sandstone Blocks and bricks are a popular building material because of the stone’s desirable features, attractive looks, natural finish and the superb thermal and acoustic properties the stone offers.
  • Limestone and Sandstone blocks have been used in building for 1,000’s of years as although the stone is dense in its composition it is relatively easy to shape and work with making it easy to lay and offering outstanding finishes.
  • Limestone and Sandstone are both a perfect material for the construction of residential homes and commercial buildings.
  • This construction method can be used as a new ‘ground up’ laying approach where blocks are simply mortar bedded together similar to brick construction or the stone supplied in a cladding material which is adhered to an existing surface not dissimilar to tiling.
  • BRUHN Limestone produce both full block and veneer products all dimensionally cut and delivered to site ready for immediate laying

Sandstone Blocks in Home Construction

Sandstone blocks are a popular choice in domestic building construction where the design calls for:

  • Thermal isolation
    Sandstone and Limestone has superior thermal isolation, protecting the home owners from the winter cold or summer heat. As an example BRUHN Limestone offers 3 times the thermal properties of a clay brick.
  • Fire Resistance
    Sandstone and Limestoneis non-combustible and so fire resistant. CSIRO reports of exact FLR performance are available on request
  • Sound Proofing
    Sandstone and Limestone have strong sound proofing characteristics
  • Embodied energy rating
    Sandstone and Limestone have outstanding low embodied energy ratings when compared with prefabricated /man made alternative construction materials
  • Affordability
    BRUHN Limestone is an incredibly affordable building material and is often misunderstood to be in a higher end price bracket. To better understand what’s involved in your project simply talk to the team at BRUHN Limestone


What’s the difference between Limestone and Sandstone?

A brief overview of Limestone and Sandstone compositions


  • Is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Limestone is predominately quite light (cream) in colour but can range into biscuit and honeycomb colours
  • Our Mount Gambier Limestone (fossiliferous limestone) is located and quarried from the Marte deposits, 10km west of Mount Gambier in the South East of South Australia
  • The stone originated from extensive colonies of bryozoa (or lace coral) that flourished on an open-marine shelf, formed over 30 million years ago. Its composition consists of bryozoa, foraminifea and echinoid spines and plates



  • Is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains
  • Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth’s crust. Like sand, sandstone may be any colour, but the most common colours are tan, brown, yellow, red, grey, pink, white and black
  • Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts
