Knight Optical’s Brick by Brick: The New Technologies That Are Building the World’s Housing Stock

POSTED 12/20/2022

 With a global housing crisis on our hands – particularly an undersupply in England, where we're also suffering from a skills shortage in the construction industry – there's high demand for new-build properties that are built swiftly, to high quality and at a lower cost.

Difficulties in sourcing the right staff with the right skills and following the complications that came from working on site during times of social distancing have brought the global construction industry under the spotlight in recent years. And the skills gap didn't just impact us here in the UK. Countries from Australia and Spain to Greece, Portugal and even the USA have all felt the consequences of a deficiency in trained labour.

With overpopulation and its resource-exceeding effects, housing levels are becoming vitally low, and it’s not just the UK feeling the ramifications. Australia is also preparing to batten down the hatches as it heads into a "decade-long housing supply crunch1". With homeownership incentivised as an investment, housing supply, especially in cities, has been severely restricted over recent years. Here in the UK, residents in highly populated areas, such as London and Brighton, have witnessed this first-hand. This insufficient housing stock is driving up house prices, resulting in affordability issues for Britain’s first-time buyers trying to get a foot on the property ladder2.  

How is the Construction Industry Closing the Skills Gap and Meeting Housing Demand?

The two challenges highlighted, the housing crisis and skills shortage, have together encouraged the housebuilding sector – and general construction industry, which is notoriously archaic when it comes to the adoption of modern-day, time- and cost-saving technological solutions – to explore new territories in the worlds of technology and automation.

Let’s explore the tech-savvy systems the sector is slowly integrating into its arsenal.

 Smart Structures

Laying Bricks and Blocks on Site

Throughout the world, contractors have turned to robots to help speed up the process of building the homes that are so desperately needed. In Australia, a country we've already mentioned for its shortage of housing supply, one example of using automation comes in the form of a brick-laying machine, which can lay bricks significantly 10 times faster than manual labour. Perth-based Fastbrick Robotics’ Hadrian X Robot (not pictured) can lay a house's walls on site in just one day.

Meanwhile, here in the UK, York-based company Construction Automation has recently received approval from The National House Building Council (NHBC) – known for its work in improving the construction standards of new-build homes – for its brick-laying robot. Capable of laying bricks, blocks and mortar, the Automated Brick Laying Robot (ABLR) [not pictured] features a gripper arm and dispenser and follows architects' plans.

Taking the Construction Process Off Site

 In a move that's been labelled as modern methods of construction (MMC), many housebuilders have taken construction work off sites to erect homes in factory-controlled conditions, which not only improves quality but also enables everyday processes to go ahead whatever the weather.

Offsite Robots

Of course, factories and automation go hand in hand, so it's no surprise that robots are forming part of the production line for offsite construction. Following in the footsteps of automotive factories, many firms have deployed their systems to assist in the housebuilding process.

Kawasaki Robots, for example, stand proud on modular housebuilder Sekisui Heim production line, boasting 30 different welding programmes to meet the floor-specific requirements of each housing unit. Following welding labour shortages, Sekisui Heim has found robotic solutions are a more effective means of production, rather than relying on the scant staff available for this line of work.

Offsite construction Lasers

 Alongside hi-tech robotics, ultra-precision lasers also feature in offsite construction factories, where they're used for pre-fabrication purposes for partially or fully assembled structures. For housebuilders like UK-based LocaL Homes – which offers high-quality, high-performance, low-carbon housing solutions – lasers have been brought into factory environments to ease the manufacturing process. Specifically for this housebuilder, lasers are used to ensure accuracy when making any cuts.

You'll also find laser-based systems on development sites to survey and assess locations and create 3D renders. Delivering high levels of accuracy and detail, 3D scanners enable surveyors to analyse hard-to-reach or dangerous areas, provide 3D walk-throughs and models and, ultimately, save contractors spending more time than necessary on sites.

Creating the Perfect Finish

 It's not just the construction of a home that can be undertaken autonomously. Once the walls, ceilings and floors have been built, other robots can be brought in to apply the finishing touches to spaces, such as drywall finishing. Construction robotics company Canvas has built a large-scale device that does just that. Ranked number 13 on the Silicon Valley Business Journal/San Francisco Business Times 2022, the robotics brand has built a robot that changed the game for drywall finishing.

3D Printed Homes

From ultra-modern homes in Germany to multi-storey properties in Houston and cabins in New York, what was once considered something from the distant future not too long ago is now becoming a reality for many. News of 3D printed homes is popping up from all corners of the globe. Typically using a towering 3D concrete printer, coupled with more traditional methods – such as wood framing – these 3D printers are speeding up construction times, with some taking a mere 220 hours to print a structure3.
