Repair that building instead of tearing it down

Climate change: Construction companies told to stop knocking down buildings​

Demolition of Robin Hood Gardens in east London

Housing estates, such as this one in east London, have been demolished to make way for newer buildings
Britain’s top engineers are urging the government to stop buildings being demolished.
Making bricks and steel creates vast amounts of CO2, with cement alone causing 8% of global emissions.
They say the construction industry should where possible re-use buildings, employ more recycled material, and use machinery powered by clean fuels.
They are concerned about "embodied emissions", which is the CO2 emitted when buildings and materials are made..

They believe that unlike carbon from aircraft, vehicles and gas boilers, embodied emissions are not in people's minds.
They suspect few people realise there's a carbon impact from, for instance, building a home extension.
The report, steered by the Royal Academy of Engineering, said a new way of thinking is needed before planning new homes, factories, roads and bridges.
Prof Rebecca Lunn from Strathclyde University, one of the report's authors, said: "Our biggest failure is that we build buildings, then we knock them down and throw them away. We must stop doing this."
Fellow author, Mike Cook, adjunct professor at Imperial College, challenged the government's £27bn road-building programme because of the embodied emissions created to obtain the concrete and tarmac, as well as the use of very polluting machines to construct the highways.
Prof Cook told BBC News: "We have to radically revise the way we look at things.
"The most important thing is to maximise the use of existing road infrastructure by using smart motorways to maximise every inch of tarmac."
Speaking in a personal capacity, he added that the decision on Heathrow expansion should be re-visited following stronger warnings from climate scientists.
Prof Cook said questions should be asked whether projects such as HS2 - with its massive embodied carbon - will really benefit future generations.
The Chartered Institution of Building Services Engineers' Dr Julie Godefroy urged the government to set targets for the construction industry to move swiftly towards zero carbon, including embodied emissions.
She observed: "We have to avoid demolition and new-build. Often most of the material in an existing building is underground - so we should seek to use existing foundations."
A spokesperson for the Department of Business, Energy and Industrial Strategy (BEIS) responded to a request from BBC News for a comment by stating that the UK was a "world leader in tackling climate change".
They added: "We are committed to reducing emissions from the construction sector, and have set up the Construct Zero programme to support the industry to achieve their climate commitments."
The spokesperson said that the government, earlier this year, had set out their Industrial Decarbonisation Strategy, which was "the government's comprehensive assessment" of how industry, including the construction sector, could decarbonise in line with the government's net-zero plans.
Also, they explained, ministers this week had announced £220 million of funding to help UK industry reduce their carbon emissions and improve energy efficiency.

Refurb over rebuild​

The Royal Institution of Chartered Surveyors (RICS) estimates that 35% of the lifecycle carbon from a typical office development is emitted before the building is even opened. The figure for residential premises is 51%.
The report has heartened the Architects' Journal, which has been campaigning against any unnecessary demolition.
It wants the government to change the VAT rules which can make it cheaper to rebuild than to refurbish a standing building.
Its managing editor Will Hurst said: "This staggering fact has only been properly grasped in the construction industry relatively recently. We've got to stop mindlessly pulling buildings down."

I'd like to see policies enacted that dramatically increase the cost of new construction and provide incentives for refurbishing older buildings.
Construction needs to get cheaper, not more expensive. The industry has improved modularization in larger buildings, but construction of single dwellings is in dire need of disruption. I'm hoping that companies like Boxabl can work out.

They have nice homes. Property taxes and homeowners insurance need to come down also If the government would reroute my leach fields and install a completely new septic system for a small house no more than 400 square feet I would let them put the house on my property.

I don't think building a bunch of disposable buildings is the way forward. There are many great buildings sitting empty that could be refurbished and used rather than clearing more land for our ever increasing sprawl.

Oh sure, but that's not about making it more expensive. That's about forcing building on brownfield.
But also they need to make sure that all the dumb rules about "character" are removed so it's easier to modernize the building.

Boxabl isn't about disposable buildings, it's about making efficient buildings that are fast to assemble on top of the foundation.

With the Boxabl you still have shipping and permit costs. Add in plumbing and electrical. An HVAC system and a foundation you could be above 150,000 dollars It appears that the shipping costs are between 3 and 10 dollars a mile

The Boxabl has HVAC. You need a foundation, water and electrical hookups.
