Outdoor Fireplace Kits: A Stylish, Simple Way to Transform Your Backyard

Written by Imogen Bailey | Aug 5, 2025 12:51:21 AM

An outdoor fireplace adds warmth, atmosphere, and a striking focal point to any backyard. Whether you're hosting guests or enjoying a quiet night under the stars, there's something undeniably inviting about a real flame. 

But building a fireplace from scratch can be complex and time-consuming. That’s why Trendz Fireplace Kits offer an ideal solution delivering high-end results without the hassle of a full custom build. With precast concrete construction, fast installation, and customisable styling options, our outdoor fireplaces help you create a stunning outdoor feature with ease.  

Why Choose a Precast Outdoor Fireplace Kit? 

Let’s face it: even in Australia's warmer climate, outdoor living areas can lose their appeal once the sun goes down. But with the right heating solution, you can turn your patio, alfresco, or backyard into a year-round space. 

Outdoor fireplace kits make it easy to extend your living outdoors, especially when you choose a precast design that removes the stress of sourcing materials or managing a full DIY build. 

At Trendz Fireplaces, we specialise in precast concrete fireplace kits, each engineered to install quickly and deliver lasting performance. Whether you're a builder, landscaper, or confident DIYer, our kits simplify the process without compromising on style or heat output. 

DIY vs. Precast: What’s the Best Option? 

There are two types of fireplace kits: DIY builds and precast kits. 

  1. DIY fireplace kits require you to source materials, plan the construction, and manage the entire build. While this might appeal to experienced hands-on homeowners, it can easily result in delays, budget blowouts, or subpar results. 
  2. Precast fireplace kits, like ours at Trendz, offer a much simpler and more reliable alternative. Each fireplace comes with a precast concrete shell and a 6mm steel firebox already installed. It’s craned into place, fixed to a concrete foundation, and finished with a quality flue system. No guesswork, no stress. 

Fireplace Styles to Match Any Outdoor Space 

Trendz fireplace kits are designed to be customisable, so you can achieve the perfect look for your home. Choose from six unique profiles: 

  • Mini Burton: A compact version of the Burton, perfect for courtyards or smaller decks where space is limited but style is still key. At 1400mm wide it's only mini in comparison to the Burton. 
  • Burton: A bold, contemporary centrepiece. Its larger footprint suits spacious patio areas or open-plan outdoor zones. 
  • Douglas: Timeless and versatile. The Douglas works well in both modern and traditional gardens and can be styled to match any aesthetic. 
  • Hudson: Clean lines and a modern profile make the Hudson an excellent choice for minimalist, architectural spaces. 
  • Single Peak: A sculptural, streamlined profile with strong vertical lines for maximum visual impact. 
  • Twin Peak: One of the largest precast fireplaces on the market, perfect for expansive backyards or luxury outdoor entertaining areas.

3 Easy Steps to Installation 

Installing a Trendz fireplace kit is quick and straightforward. Here's how it works: 

  1. Pick your fireplace & prepare the foundation
    Choose your preferred model. Then either contract a professional or DIY a concrete pad (all dimensions are provided in our installation guide). 
  2. Place the precast shell
    The concrete fireplace shell, with steel firebox already installed, is craned into place via a Hiab truck and secured to the foundation using the supplied brackets. 
  3. Install the flue 
    Fit the flue (or dual flues for the Twin Peak) to ensure safe and efficient smoke ventilation. 

From there, you can customise the exterior with the finish of your choice; plaster & paint, stone, brick, or raw sealed concrete. Not keen on DIY, you can order your fireplace to be plastered and painted before it's delivered, in your choice of colour. Stuck on what colour to pick? We have a few suggestions.

Gas or Wood-Burning: What’s Right for You? 

Choosing between gas and wood-burning depends on your lifestyle and how you use your outdoor space: 

  • Gas fireplaces are convenient and clean burning. They provide instant heat with no mess and are ideal in suburban areas where smoke may be a concern. 
  • Wood-burning fireplaces create a more traditional ambiance. The smell of burning wood, the crackle of logs, and the ability to cook over the flame all add to the experience. If you're after authenticity and that unmistakable outdoor charm, wood is hard to beat.
