Indian coffee house trivandrum, kerela

Presentation on ICH, trivandrum by Laurie Baker. It talks about vernacular architecture used.

1. Indian Coffee House Trivandrum, Kerala Laurie Baker

2. One of the prominent landmarks in the Thampanoor area of Trivandrum, where both the railway station as well as the bus terminal are located, is the Indian Coffee House designed by Laurie Baker.

3. Laurie Baker Architectural Style Followed NEO VERNACULAR ARCHITECTURE style. Neo-Vernacular Architecture that drew on brick, tile, and other traditional materials and even on vernacular forms in a general reaction against International Modernism in the 1960s and 1970s. Brick jaali walls, perforated brick screen which utilises natural air movement to cool the interior and create patterns with light and shadow. Avoided energy intensive materials. Curved walls to enclose more volume at lower material cost than straight walls. Designs incorporated the existing trees and vegetations and make them the part of it. His main construction material is BRICKS.

4. About The form of the building is unconventional & bears Baker’s trademark jaalis to let in light & ventilation. The building is well proportioned, a cylindrical brick-red spiral continuing for a couple of floors and then terminating in a smaller cylindrical volume on top, giving a very unsymmetrical balance to the whole structure.

5. About The entire building is conceived as a continuous spiral ramp, with a central circular service core and with dining spaces provided on the outer side. The table and the seats are built-in.  Around the circular core are the service areas, especially the toilets The kitchen is placed on the ground floor and has a separate service entrance

6. Features BRICK- Locally available material in, and around Trivandrum Ability to absorb and release moisture, resulting in regulated temperature and humidity inside. Excellent compressive strength Fire resistant and sound insulation JAALI- It is a better substitute for a glass window Lets in general subdued light Provides ventilation and prevent entry of rain It saves materials resulting in less cost and speedy construction.

7. Stack Effect There is a circular service core in the centre, which consists of 2 concentric circles. The inner smaller circular core is a narrow vertical shaft open on the top, with openings at different levels. This shaft provides ventilation to the central areas and works on the principle of Stack effect, a very simple but effective solution that is so typical of Baker.

8. Stack Effect Since buildings are not totally sealed, the stack effect will cause air infiltration. During the heating season, the warmer indoor air rises up through the building and escapes at the top either through open windows, ventilation openings, or unintentional holes in ceilings, like ceiling fans and recessed lights. The rising warm air reduces the pressure in the base of the building, drawing cold air in through either open doors, windows, or other openings and leakage. During the cooling season, the stack effect is reversed, but is typically weaker due to lower temperature differences.

9. Construction Technique Rat trap bond is used as the construction in this building. RAT TRAP- is a cavity wall construction with added advantage of thermal comfort. It is an alternative to normal English bond masonary walls by which 15% of cost can be reduced without compromising the quality, appearance and strength.
