Leather is not technically a fabric but a material. The quality of a leather piece mainly depends on what type of “grain” it has. Full-grain leather is generally considered the highest-quality type and refers to leather that has not been sanded, buffed or corrected to retain the skin’s natural fibre strength and durability. Top-grain (also called corrected grain) and split grain leather have been more heavily processed (the top layer of the skin is usually removed), and are therefore not as durable as full grain leather, and also won’t develop that coveted natural patina of high-quality leather over time. One way to check whether a leather item was made from full-grain leather is to look closely at the tiny grains on the fabric. Do they look natural or printed? Full-grain leather contains all the natural imperfections from the animal it came from. Brands that use corrected leather will sometimes print marks back on to the sanded leather, to add authenticity. Some more notes on leather quality:
We call the Judge Institute complex a "Brookestead
Block®"', after Addenbrookes and the ideas underlying
the new design. It is made of separate buildings that embody
a " Republic of
the Valley® " between their sides. This tiered
"valley" gives an Institution a "natural" space in which to
'embody' its society and hence a 'green' foundation..
Technically, the building addresses 'green issues' because it:
1. is in the centre of a beautiful old Mediaeval city.
2. introduces "synthetic masonry" to Architecture of the highest quality, avoiding the need to use rare natural cladding materials..
3. Is designed to attract the business corporate community but has hardly any car parking. It has cycle parking for 250 units.
4. re-uses a huge old civic building: the City Hospital, by modernising it without compromising with any repro-styles.
5. keeps its rooms well day-lit.
6. uses no A/C on a dense urban site by employing the " Solar Spiral" making large rooms very high and a using solid roof over the central atrium. Projecting fins also reduce solar gain through windows.
7. maximises the use of stairs, which is beneficial for health, by keeping floor to floor heights (8'6") very low indeed.
8. uses no propped floors or suspended ceilings, exposing the thermal mass of the concrete floors.
9. Creates a new kind of "landscaped" work-space for the computerised work culture.
10. Introduces radically new ways of organising building services and architecture: the "Working Column" and the "Working Beam", both parts of the "Sixth Order" , which simplify maintenance and 'cost in use'.
11. Introduces the roof garden as an integral part of the workspace, concept and function.
