710679Mass Bespoke: a digital construction system from Bauman Lyons ArchitectsClosedGRD Proof of ConceptInnovate UKThis project demonstrates a system, ‘Mass Bespoke’ (MB) that joins parametric design & prefabrication to assist self/custom home builders. MB enables ease of construction & allows distributed fabrication, so those with limited experience can build to a high quality, meeting Passivhaus standards where desired, at a lower cost than traditional building methods. Whilst discussing prefabricated houses to meet the housing crisis, Design for Homes’ David Birkbeck said: ‘Prefab works well if you have extensive repetition. But we don’t do repetition in the UK because… of oddly shaped pieces of land requiring sensitive responses… we have yet to see a successful example that has broken out from the niche.’ MB Bespoke addresses this issue by incorporating parametrics into a system that outputs bespoke, modular, prefabricated houses, the issue of varying land shape & form is ameliorated by overcoming the previous constraints of repetition. MB brings increased level of cost/build certainty to early design stages, making building easier to engage with. Bauman Lyons (BL) propose a £130,514 POC project to develop MB. MB uses parametric design to enable users to explore various design iterations rapidly & easily, but with enhanced functionality over that already available by: 1) providing performance, cost & quantity information up-front 2) outputting files ready for the BIM environment; 3) outputting files ready for 3rd party software conversion into g-code, to enable pre-fabrication of construction components; 4) integration of engineering into MB, allowing structural requirements to adapt automatically with changes to geometries & components. MB seeks to automate the output requirements for building regulation approvals. MB satisfies two Government drivers: 1) a need for increased self-build; 2) a need for smart construction/digital design by 2025. MB will expedite builds, as other components (such as windows) can be ordered at the same as the MB construction system.
