Myths about building with Limestone

Myth No 1. Limestone is Expensive

Often people think that building in limestone is a complex and a costly process but in fact, it’s exactly the opposite as building in BRUHN Limestone has the exact same building principals as building in brick and is very similar in price to brick / render construction.

As an example, the most common approach to building a home in Australian conditions is to lay a concrete slab and then build a timber or steel frame to support the roof structure. After this process, the home is wrapped with an external skin whether that be brick, block, lightweight or stone products.

Myth No 2. Limestone is difficult to build with

As BRUHN limestone blocks arrive to site dimensionally cut and ready to lay directly off the pallet, the block or bricklayer simply mix their mortar and lay blocks identical to bricks around the home.

Construction incorporates weep holes and expansion joints again identical to brick construction that any reputable architect and builder should be completely familiar with.

Certainly there are a few tricks with building in limestone; like using a light coloured mortar to match the stone and to wet the laying beds with clean water before laying but in summary building in limestone is a simple process and offers a beautiful timeless look as well as offering superior thermal and acoustic qualities.

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.

Using Limestone in your new home

Your Unique Home

showcase-grand-13The common theme that architects and builders often hear when speaking to clients is that the end user always wants a uniqueness to their homes and I suppose why wouldn’t they!. If your designing a custom built home it should be reflective of your lifestyle, family needs and pick up the personality you are striving to achieve in the ideal home of your dreams.

Certainly designing the floor plans needs to suit these lifestyle requirements and should be well thought out with a good custom builder who listens and works closely with you. If you achieve this good balance in the relationship you will eventually design this ‘floorplan footprint’ and all the planning will soon turn into excitement of what the end result will look like and how quick can we make this happen.

External Cladding makes the Home

But it’s the ‘look like’ and the ‘uniqueness’ of the external cladding of your home that will set it apart from what everyone else is doing and immediately build resale value from the moment you receive the keys. The external cladding of a home is like the ‘dress sense’ or ‘make up’ worn by us as individuals and we are offered opportunity and many options to select this exterior persona as a reflection of who we are and how we would like our new home to look in the design stage.

Limestone gives an ‘individual look’

When investigating what cladding options are available to achieve this ‘individual look’ we discovered natural limestone offers all the above options due to its incredible versatility in product and colour range and the ability for it to simply just fit into all housing design options is quite remarkable.

Limestone is traditional

If it’s a more of a traditional type home that suits your taste, limestone blocks are now complemented with a broad range of decorative mouldings so plinths, wall bands, window moulds and parapet capping is now all easily achievable. If it’s a more modern contemporary designs that suits your liking limestone offers clean crisp lines that complement timbers and steel to create the most beautiful architecturally designed structures.

There is just something about natural stone that offers an immediate warmness and beauty to a home as well as the additional benefits of the superior thermal and acoustic properties that come with it.

Limestone Myths

Building in stone is also often misunderstood as being very expensive and difficult for builders to pull together but this is simply a myth as building in limestone has the exact same principals of building in brick and there are a large number of stonemasons in Melbourne who specialise in working with Limestone at very affordable rates. These masons can work magic with the stone to create features and detail both externally and internally that can offer the uniqueness you are looking for.

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


Limestone… More affordable than you may think.

Limestone…its more affordable than you may think.

limestone buildingBuilding a new home or adding an extension can be an expensive exercise and there is certainly a lot to consider and a massive amount of decisions to be made during the whole process.

However building in limestone blocks / bricks can be very economical and should be considered as an option to create a beautiful, natural and affordable solution.

Did you know that limestone blocks are very similar in price to clay bricks and other light weight construction materials currently in the market?

Certainly when you consider adding render and paint to these material limestone blocks can actually have a price advantage which should at a minimum tease people to explore the options of building in limestone.

Over years of dealing with clients I have learnt many people often misunderstand the costs to build in limestone as when they think of natural products they always think it comes at a premium price but it’s not the case with limestone blocks and bricks.

With the limestone resources available to us at our quarry, combined with the efficiency we exercise to cut and prepare dimensional stone, building in limestone has reinvented itself as an affordable option that looks absolutely stunning when used in external and internal walling.

Combine these appearance and affordability benefits with the superior thermal and acoustic qualities to brick and limestone blocks should be considered for your next project.

These moulds have been designed to extend the options for window and door surrounds, wall bands and parapet capping and complement our existing ashlar blocks selection.

Andrew Carmody from BRUHN Limestone said “Because architects and builders are always looking for something different it makes sense to ensure we are supporting their needs. Certainly if a client wants something never seen before or in some cases trying to replicate a style of home built anywhere in the world we have some fantastic options”. Andrew also went on to say “Often BRUHN Limestone is perceived as being an expensive building material but we continually surprise people of how affordable our stone is. We encourage anyone that wants a solid home built to give us a call as we are confident you will thank yourself for making this first step”

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

Tips for selecting Limestone and Sandstone Products

Limestone and Sandstone quarries are still very active in the Australian market with a broad range of quarries in Australia still operating and producing quality dimensional stone.

The large majority of all these quarries are professionally run and produce high quality natural products, however there are areas in the decision making process that client’s needs to consider:

  • Availability and Turnaround
    When choosing any stone products always fully understand the products availability and turnaround time as delays on site can be frustrating and costly
  • Consistent Sizing
    Understand consistency of sizing, as ashlar blocks supplied in consistent dimensions represents less work for the mason, minimising project costs
  • Product Range
    Fully appreciate the range of products from the supplier as many quarries offer various face finishes and decorative moulds
  • Colour Consistency
    Ask about consistency of colours as being a natural product colours often vary. (Source current samples)
  • How much do you need?
    Have an approx. idea of the m2 of your project. This information can generally be sourced through your architect, builder or stone supplier (estimates from working drawings) and always ask for an itemised quote on the products you are interested in as this will offer complete transparency on overall product costs
  • Check similar projects
    Be sure to view other completed projects either personally or ask for a gallery of images. This information will offer you confidence in the look and feel of the stone Although all stone offers excellent thermal and acoustic qualities source exact ratings
  • How will the Limestone be used?
    Understand the building process, as some stone can be used as a cladding (stone tied to frames) or as double skin construction. In some instances veneer stone is adhered to cladding often exaggerating construction costs
  • The value of an experienced stone mason
    To fully appreciate the costs of building in stone you should always engage an experienced and qualified stone mason to talk you through the building process, as various stone products can vary in their laying costs due to their weight, sizing and the need for the stone to be dressed
