Advantages, Added value of Restoration (1)

• Multiple advantages:

• - Economic • - Added value:

Advantages of Restoration (2)

• Great savings in producing productive real estate, reducing the enormous cost of commercial rental of office space by multiple ministries of government and other government entities.

Advantages of Restoration (3)

• It will save foreign exchange, with emphasis on labour, rather than the enormous amount of imported materials used in most major new buildings today.

Advantages of Restoration (4)

• It will hugely improve the aesthetics and quality of our environment, leading to further restoration and improvement of the built environment (“follow fashion”)

Advantages of Restoration (5)

• It will help to ensure that our very, very tenuous award of UNESCO World Heritage status, with its huge tourism, economic and other benefits, is not withdrawn through increased dereliction of historic treasures in the historic core of the city.

Conclusions

• Restoration is usually cheaper than new building, unless the roof has fallen in and trees growing

• Restoration of solid coral stone walls two feet thick, with plaster quoins, mouldings, ancient tiles etc. is almost always cheaper than rebuilding TO THE SAME STANDARD

• Restoration is labour intensive, saves Foreign Exchange and respects heritage and craftmanship

• Solid foundations and walls are half the battle!
