UK: initiatives to revitalize the housing market

Measures to revitalize the housing market will be launched by the British Government.
First, the Government will underwrite a portion of mortgages on newly built homes. A direct consequence is the reduction of the deposit that the buyers of the property must pay to access the mortgage on housing. The proposals from the banks are very varied. The only common point is the amount of the deposit to be paid by first home buyers for newly constructed buildings, which is never below 20% (that is financed only 80% of value), due to uncertainty about the real estate value. In this case the government aid will allow to decrease the percentage of the deposit to less than 5%, thus laying the foundations for a revival of the real estate market on new constructions. Homebuilders will contribute to 3.5% in the allowance, the rest will touch the government (or taxpayers, as it is written in the UK). There is the fact that it seeks to reverse the trend that has seen first time home buyers from 600,000 in 1999 to 200,000 last year.
Another initiative of the Government is the allocation of 400 million pounds in support of housing developers, in particular in order to build on land that the owners currently consider uneconomic.
The package is much more articulate, but what I want to emphasize here is something else.
In hindsight, such are initiatives, as part of a research strategy for economic growth, that certify the acknowledgment of the construction sector as a central industry
I do not know if such initiatives are or are not appropriate or correct; the emerging observation is that once again the housing market is vital to the economy of a country, especially when you want to seriously address a policy of stimulating economic growth. Not only for the  industry itself, which still delivers high levels of employment, but also and especially the huge induced (artisans, sole employer, small-medium size companies)which is able to generate and involving other vital sectors of production and trade.
