Prefab Comeback

Prefab  housing suffers from bad stigma due to the fact that some people saw the prefabs as ugly and characterless, and were afraid they would become slums – hardly the promised housing fit for heroes  following the second World War. However, building homes from pre-made parts can save time and money.  The term prefab or prefabrication often evokes thoughts of poor construction, substandard living conditions and a long-standing “temporary” solution.

Prefab dwellings are making a comeback driven by a lack of affordable housing, a rapidly growing economy and changing demographic trends.  

Methods Methods of Construction (Mmc) Offer Significant Potential to Minimise Construction Costs

The term ‘Modern Methods of Construction‘ refers to a collection of relatively new building construction techniques that aim to offer more advantages over traditional construction methods. Off-site construction (OSC) is a modern method of construction, based on off-site manufacturing of building elements.

With exponentially lower construction costs, quicker construction, reduced  labor costs and having the ability to achieve zero defects, MMC is gaining a lot of attention as the  potential answer to the UK’s housing crisis.

In a valiant attempt to strip away prefabricated housings’ bad rep are MMC with contemporary sleek designs, and constructed to withstand the test of time. MMC housing has the capability to deliver both quality and quantity housing to the tune of ‘ £50,000 per unit.

MMC units hold the promise of being extremely  energy efficient and environmentally sustainable. Many versions of MMC take into account how to utilise natural resources and reduce each unit’s carbon footprint. In addition, MMC also addresses environmental concerns by creating much less waste than a standard brick-and-mortar project. While it is plausible that a traditional build could hire a waste removal company who would have the ability to recycle up to 90 percent of the construction waste; with MMC projects, this will automatically happen.

There have already been a number of successful examples of MMC housing constructed in various parts of the United Kingdom. The M-house (pronounced “mouse”) is designed and constructed to last an upwards of 100 years. While Architect Alford Hall have created quality MMC apartment buildings proudly showcasing a patio and private entrance for each flat.

While many of the MMC homes  are still in their early years the upkeep and maintenance will be reduced by 50%  since the OSC  process lowers the risk of non-conformities.

MMC homes are being fabricated and designed to accommodate many different lifestyles, such as, two-story homes, tall six-story apartment buildings, single-family homes and log cabins are all available options for families looking at MMC.

While there is a plethora of design options available all MMC  OSC  projects have a common theme. The internal workings of the homes are fabricated off-site, while only the “outer skin” comes to fruition on-site. To even further streamline the process, it has been suggested that having a “catalog of pre-selected materials increases supplier relationships and makes the design process more streamlined.”

With the small sample available with progressive MMC systems, it is currently reasonable to conclude that using modern methods of construction to build homes can cost more than traditional home building procedures; due to the need for specialised MMC design consultants. However, outside of costs, MMC remains a faster home building method than traditional brick and block house building and is slowly  becoming a relevant front-runner to answer the  UK’s housing shortage.

Zero defects are the primary battleground  between traditional and modern  construction methods. A relative  concept, zero defects is, however, a  target that the construction industry  has set for itself. Primary  considerations are structural stability  and keeping the water out. Proper  functioning of services, components,  fixtures, and fittings are essential.

Energy and sound performance are  also vital, as well as issues of safety,  access, and security. This is a  campaign which will be fought in  years to come… and in the meantime  here is another prefab  scheme  which feature’s in these  skirmishes.

Mobile Modular (MoMo) is a  research development project for a  relocatable system of mass housing  constructed from specially fabricated  shipping containers. This type of  system allows flats to be erected  speedily on short-life sites and to be  demounted and re-assembled in  different configurations on other sites  in the future.

The key objectives:

Remove MoMo apartments from a  site where housing has been provided  for 5 years.

Refurbish Each module at the  supplier’s yard or an alternative  temporary site.

Re-locate The apartments in any  new configuration to provide  decanting, short-term housing,  permanent apartments. This type of  system can also become a  permanent housing solution.

Originally commissioned by the  Peabody Trust, after feasibility stage, the team was invited to take the  project forward with their own  initiative. The team formed a  consortium with the aim of developing  a prototype to  demonstrate  the principles, and to market the  MoMo scheme as a one-stop shop  package to interested parties.
