Our sustainability principles are grounded by the continual need for increased efficiencies, flexibility and control throughout the design, construction and extended life-time of our buildings.
We have developed (and are continually developing) technologically advanced architectural design systems to improve current design and construction-based inefficiencies. These inefficiencies occur due to the disconnection and fragmentation between the building and architectural industries, resulting in high costs, excessive building waste (as material quantities are estimated with over-runs) of each contributing industry as well as creating a lack of control for the architect over the project budget and construction timeframe. In conjunction with this, standard building practices are easily affected by complications or inconsistencies of contributing industries. If one trade is unable to deliver on time or is affected by weather, this has a roll on effect throughout the entire project, subsequently changing the timeline, budget and potential building result.
Makers of Architecture have developed a new method of cost effective, customised precision building. We have developed a cassette based design and fabrication system to work in conjunction with XLam’s structural Cross Laminated Timber (CLT) product. (CLT panels are much like enlarged plywood sheets consisting of timber boards glued together in both directions, creating an inherently solid, strong, earthquake resistant sheet material)
The cassette system utilises Building Information Modelling (BIM) in conjunction with Computer Numerical Control (CNC) machining, allowing us to create almost any imaginable building form efficiently, accurately, cost effectively and sustainably.
Using this system, the cassette components are fabricated in a factory environment, where they come together like a jigsaw puzzle. The accuracies of this system enable precise building costing/pricing (due to BIM data outputs), while also minimising material waste. The cassette panel components are cut via CNC machining, where the arrangement of the components are maximised on each plywood sheet so as to ensure very little waste is created. This process maximises cost efficiencies with minimal waste.
Flexibility is a fundamental sustainable attribute that we support. It’s important to us that our designs and systems accommodate not just current building requirements and client needs, but also the opportunity for future change. Using screw fixings in conjunction with the frictional jointing methods for the assembly of the cassette’s and CLT panels provides a fully flexible design system meaning that it can easily be; unclipped, disassembled, altered, added to, moved, reconstructed or recycled if need be.
The depth of the cassettes can vary to house any depth of insulation required. The solid wood CLT panels also hold significant insulation value and because the entire structure is wooden it is a completely sustainable renewable resource. All wood is locally sourced within New Zealand, and has a zero carbon emission. As stated on XLam’s website (http://www.xlam.co.nz/Sustainability) ; ‘Wood has zero “embodied carbon” (ie the amount of carbon used in the process of manufacturing a building product), all wood used to create the CLT panels is grown and felled within 50km of the XLam factory.’
All services (mechanical, electrical and plumbing) to the building sit against the exterior CLT surface and are housed within the cassette panels. If the services need to be accessed the cassette panels can be lifted off and the services attended to as required.
The cassette based building system has been developed to support the New Zealand DIY (do it yourself) mentality enabling clients to be an active part of their own building projects under the supervision of one qualified builder (if they choose to be). This involvement can bring the total building price down with reduced labour costs while also providing an educative experience and understanding of how the building works and performs.
While Makers of Architecture engage with technological efficiencies to achieve sustainable results, basic sustainable design principles are also applied to our buildings, allowing them to maintain healthy and stable interior environments. Passive solar design, geographic orientation, ventilation, insulation, plus solar systems such as; integrated solar Photovoltaic panels and Evacuated Solar Hot Water Tubes are included in our schemes. A strong connection with site and the surrounding landscape is an inherent attribute that we respond to in every project, again being sensitive to the site requirements and natural resources.
Financially sustainable – spending more time at the beginning of the project confirming some of the unknowns saves on; time, materials costs, contributing trades and foreseeable problems etc.
Our company has set up a research and development/experimentation workshop where we are capable of testing alternative systems, producing 1:1 prototype full scale models utilising digital fabrication technologies.
The current cassette system provides a new direction for the architectural industry, one that challenges standard design and building practice to better engage the architect with the design and building processes. The system introduces an adaptable and sustainably conscious architectural building solution for clients looking to build in any shape or form.
