Products We Offer

Composite Decking

Composite decking is a popular timber alternative that offers all the beauty of hardwood without maintenance. The result? A low-maintenance, beautiful deck that stands the test of time.

Modern colours and textures from companies like Trex, Millboard and Azek will add a unique new dimension to your home and transform your entertaining and outdoor living space. Just look at some of the benefits of composite decking:

  • no fading or staining
  • child and dog friendly
  • maintenance free
  • no splitting or rotting

Timber Decking

We’re proud to offer various options and styles, all custom-built to suit your needs and complement your lifestyle.

Affordable, elegant, and guaranteed to turn heads – that’s the timber benefit.

Choose from the mellow hues of traditional spotted gum to the more vibrant colour notes found in Jarrah decking. 

If you want a more maintenance-free timber option, ask us about teak or Kebony options. Both provide the warmth found in natural timber decking but without the need for ongoing maintenance.

Privacy Screens

Adding a privacy screen can make a world of difference to the enjoyment of your outdoor entertaining space. From screening off a utility area so it doesn’t spoil the look of your finished deck to providing privacy to both yourself and your Sydney neighbours can bring another level of use to your balcony.

Materials can vary from maintenance-free composite castellation cladding to timber look-alike, aluminium, and hardwood spotted gum timber battens that bring warmth and colour to any setting.

Balustrades and Handrails

Frameless glass is a perfect, flawless, contemporary look for your new balustrade project. It will give your terrace or stairs a smooth and sophisticated look and feel. Not only does it look fabulous, but your views will also be enhanced with a clean and unobstructed view.

For a more traditional look, the Uktralox aluminium powder-coated handrail system is not only maintenance-free but looks stunning with the simplicity of its clean lines that harken back to the times when fine detail was a feature of the building industry.

Create Your Dream Outdoor Space

Beautiful, low-maintenance outdoor decking is our bread and butter. We specialise in providing decking Sydney home solutions that tick all the boxes and, when cared for correctly, will last a lifetime. Timeless outdoor decking designs that continue to elevate your outdoor space for years to come – composite or hardwood decking, privacy screens and balustrades; we work with high-performance, durable materials so your new outdoor space can withstand extreme conditions often faced throughout the Sydney seasons.

Frequently Asked Questions

What deck boards can I choose for my Sydney decking project?

If you’re looking at building a new deck in Sydney, UrbanArch Building are the experts. We have an extensive range for you to choose from based on the look you’re after, practicality, and the climate you live in, from composite decking to Trex decking boards. Here are some of our most popular types of outdoor decking boards in Sydney:

  • Trex composite decking, available in 140 mm wide boards. Trex decking boards are the most popular decking product in Australia and the world.
  • Millboard composite decking, available 1n 176 mm and 200 mm wide boards (Enhanced, weathered and charred/emberred).
  • Azek composite decking is available in 136 mm, 140 mm and 184 mm widths.
  • Spotted gum hardwood decking (probably the most popular hardwood decking in Sydney), kiln dried and available in 86 mm and 135 mm wide boards.
  • Blackbutt hardwood decking, kiln dried and available in 64 mm, 86 mm and  135 mm wide boards.
  • Merbau – kiln dried finger jointed lengths of 5.4 metres and 4.8 metres. It’s available in 42 mm, 70 mm, 90 mm and 140 mm widths.
  • Ironbark (grey and red)
  • Turpentine
  • West Australian karri
  • Jarrah
  • Teak

How long will it take to build my deck from start to finish?

The timeframe it takes to build a new deck can vary depending on the project’s size and complexity, the deck’s location, and any preparation work that is required for us to commence work. For simple projects, the turnaround time may be less than a week from start to finish. For more complex decking projects, the process may take a few weeks or even months with some of the commercial-scale work that we carry out.

We recently completed a commercial deck and walkway area that was 127 metres long. It ranged from being almost at ground level to 4 metres off the ground in some places. The installation time for that project was seven weeks.

A 90-square-metre trex deck replacement built over two levels has just been completed in over two weeks.

Before we commence work, we draft plans and provide an accurate timeframe for work (weather permitting) so that you’ll have a clear timeframe. Like anything, we can run into unexpected hurdles that can change timeframes, but we’ll always ensure that you know how we are progressing throughout the build.

An advantage of choosing us for your deck makeover or installation is that you will have your portal login ID that gives you access to our programme to see progress on your project. You can feel free to ask questions or make comments directly through the portal, and a staff member will immediately be notified and will be able to respond very quickly.

If you seriously consider adding a deck to your property, some of the following considerations may affect how long your project will take.

  • Does your site have good access or difficult access? The more difficult the site, the longer it will take to bring materials in and take waste away.)
  • Are you looking to have a complex design or a more straightforward design? The more complex your design, the longer it will take to install.
  • Do your materials have to be specially ordered? Some overseas materials (and Australian sourced) can take up to 6 months to arrive on site.
  • What is the size of your deck? Generally speaking, the larger the deck – the longer the installation will take.
  • Adding features to your design will generally add time to complete your project. For instance, storage, bench seats and barbeque areas will add time.

How long will my new deck last?

Our business philosophy is that we may be with you for a week or two for the initial build, but the work we do on your property will be with you forever. With that in mind, we will build your new deck with only the highest quality materials and workmanship.

Well-made modern composite deck boards can be expected to last at least 25 years if properly maintained. Do a thorough check of the warranties offered by the brand you choose, and if unsure, contact us for practical information that will reward you many times over.

Properly installed and maintained hardwood deck boards will last at least 25 to 30 years. Some processes can’t be avoided if you want your hardwood deck to look good and last more than a few years. Beware of shortcuts or deals that look too good to be true. Call us for a copy of our Hardwood Decking Checklist – it’s full of tips that can save you many thousands of dollars, not to mention aggravation and heartbreak.

And last but not least is the substructure. Out of sight is not out of mind. This is one of the most critical aspects of the deck construction process. Quality decks need to be done correctly – the first time. Many of our clients are surprised at the steps in ensuring that the substructure lasts and doesn’t need thousands of dollars to fix it up. We’re happy to provide you with the advice you need to get it right – a phone call can save you a lot of wasted time and money.

I’m not sure of the deck design I want. Can you design one for me?

Yes! We have a full design service to help you to curate the perfect outdoor living space. We can work with you to add all the features of your home and yard so that you can see exactly how your new deck will look when it is completed.

3D renders and a movie walk-through of your new or revitalised outdoor entertaining area will bring your vision to life and help you decide whether the completed project will satisfy your hopes and expectations before committing yourself to the project. We have found that taking the time to involve yourself in this process results in a far superior outcome allowing you to avoid problems that may otherwise happen.

Do I need to obtain a building permit for my deck in NSW?

In NSW, installing balconies, patios, decks, and verandas may not require approval if the proposal meets the relevant development standards in the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (the State Policy).

Some of the critical considerations that will ensure that your deck is exempt from a development proposal include the following:

  • The deck must be located behind the building line of any road frontage
  • The deck must not have an area of more than 25m²
  • Not have to enclose walls that are higher than 1.4-metres
  • Not have a floor height that is more than one metre above the existing ground level
  • Not be more than three metres at its highest point above the current ground level
  • If metal is used, it must be low reflective and use pre-coloured materials
  • Decks located on bushfire-prone land must be less than 5-metres from a property
  • Decks constructed in a heritage conservation area or a draft heritage conservation area must be located behind the building line of any road frontage.
  • In some cases, it may be necessary to contact your local council for approval if existing trees or vegetation need to be removed for your decking project.

Our team will be able to assess your property and provide advice on any steps that need to be taken before moving forward with construction work. We will also consider important factors such as water mains, power lines, and storm drains to ensure nothing is disrupted during the building process.

Have you built many decks?

Over the last 12 years, we have built over 500 decks for significant project home builders and private clients. We specialise in building decks to the highest quality and standards. If you’re looking for the best decking Sydney-wide, look no further than the experienced, diligent, and friendly team at UrbanArch Building.

How good is composite decking?

Composite decking is fast becoming popular among deck builders in Sydney and their customers. It includes everything from capped decking boards to polyurethane and PVC composite boards. If you choose the right composite board for your situation, you will achieve a fantastic look and get a deck that will give you many years of maintenance-free use. For any outdoor living area, composite decking materials and decking boards are suitable for pool decking and restoration of your existing deck.

What can I add to my deck that will make it more functional?

We can add a wide range of options to your deck for you. Planter boxes are perfect for extra screening and privacy. Plants will also soften the look of large deck areas. Privacy screens will give your deck a more intimate and cosy feeling. Built-in seating and storage will increase the usability of your deck. You can incorporate a built-in barbecue or pizza oven if you like entertaining. Deck lights will add that something extra to your deck that will make it sparkle. Contact us for more ideas.

Composite vs. timber decking – Which should I choose?

Choosing between natural timber and composite decking is one of the most complex decisions you’ll have to make for your new deck. So, which is suitable for you, and what are the pros and cons of each option? Here is a quick run-down of the difference between composite and timber decking and how you can choose between the two.

Pros of composite decking

  • Highly durable
  • Resistant to rot
  • Low maintenance decking
  • It doesn’t require staining or sealing

Cons of composite decking

  • Price – more expensive than timber
  • Finish – some prefer the look of natural timber

Pros of timber decking

  • Natural look and feel
  • It can be stained or painted to match your home
  • Affordable decking material

Cons of timber decking

  • Requires more maintenance
  • It does not last as long as composite decking
  • Can rot when not adequately maintained or sealed

Still not sure if composite decking or timber decking is right for you? Don’t stress; our team can run you through a total cost breakdown and let you know which deck would be most suitable for your desired outcome.

Can you install decking over an existing surface?

Decking can be installed on an existing surface, provided that the surface is level and in good condition. Any moisture, rot, or damage to an existing surface must be fixed before proceeding with any construction.

It is important to remember that decking is not designed to provide a ‘veneer’ layer to an old deck. Instead, it must be constructed on a suitable surface that can safely support the weight of new materials. The existing surface must be stable and be able to handle the weight of the new decking.

How can I maintain my new deck?

Like anything, decking maintenance is your key to longevity and ensuring that your deck stays in tip-top condition over time. A Sydney home deck is prone to extreme weather conditions, so it is important to practise proper decking maintenance to maintain your investment.

As a major Sydney deck builder with years of experience, we can’t emphasise enough the importance of regular deck maintenance to keep your deck’s pristine quality and ensure decades of trouble-free enjoyment.
If you are concerned about deck maintenance, you can take advantage of several services we offer our clients.

Some of the steps that you can take to prolong the life of your deck include:

  • Sweep and blow leaves and debris off your deck as they build-up
  • Clean your deck with a mild water and detergent mix, or use a specialised deck cleaning solution.
  • Have your deck inspected for any rot or signs of wear so they can be fixed before they become a bigger problem.
  • For timber decks, apply high-quality oil to protect the deck boards from moisture and UV rays.

The materials you choose (composite vs. timber) will ultimately determine how often you need to maintain your deck. In comparison to timber decking, composite decking usually is considered low-maintenance decking material. Whatever decking material you choose, composite or timber decking, following a maintenance plan is a surefire way to keep it looking its best.

If you are concerned about deck maintenance, you can take advantage of several services we offer our clients.
          1) An annual inspection of your deck. One of our specialist staff members will inspect your deck and provide you with a detailed report and any steps that may need to be taken to ensure the longevity of your deck.
         2) A maintenance programme that is specifically tailored to your requirements. This includes an annual inspection and any repairs, cleaning, sanding and re-oiling that may be needed. This service is best for hardwood decks.

Please get in touch with us for more details on our deck maintenance services for composite decking and timber decking boards.
