15. PRINCIPLES OF HOSPITAL DESIGN
TOTAL AREA
SITE PLANNING
Landscape elements such as open areas , horticulture to increase
the comfort conditions inside the building and also in the
surrounding environment should be kept in view.
ORIENTATION
STRUCTURAL GRID
LANDSCAPING
The total area to be provided for a hospital shall depend on
availability of land , however an area of 1 hectare for every 25
beds is recommended.
Sensitive areas like wards , consulting and treatment rooms &
operation theatres are placed away from the outdoor sources of
noises.
The most suitable orientation for treatment and operating rooms is
between N-W & N-E.
For nursing wards facades south to south-east is favourable ;
pleasant morning sun , minimal heat built up little requirement for
sun shading , mild in the evenings.
East and West facing rooms have comparatively deeper sun
penetration , through less winter sun.
Then constructional grid must provide a precise guide as well as
allowing for differentiation of areas for the main functions ,
support functions and vehicular traffic.
Then variation operations centres can be planned most
appropriately with a column grid spacing of 7.2m or 7.8m smaller
construction grids are problematic because large rooms (eg.
operating theatres) which must be free from internal columns are
more difficult to accommodate.

SITE SELECTION
LOCATION :
ORIENTATION :
SITE ANALYSIS :
SURROUNDINGS :
ENTRANCES :
Located in sector 62, Phase VIII, S.A.S. Nagar, Mohali (Distt.
Ropar), Punjab, India - just 7kms , from Chandigarh.
Very near to the bus stand - Thus comfortable to the patients
coming from out of city.
It is 14kms from the airport, 9kms from bus stand (sec 17) &
12kms from the railway station.
The approach to the site is from a 24m wide road running
all around the site.
It has PSEB building on one side & the Punjab Urban
Planning & Development Building opposite to it and a
proposed market behind it.
The building faces north-west, the most favourable
orientation.
Care has been taken to place the curved surface of the
building out to that direction to get the maximum exposure
to glare-free light.
The linear proportions of the site 3:1 have brought out the
linear plan of the hospital building , the two entrances
being on the longer side.
Spread over 8.22 acres.
Rectangular plot : 344 x 110m
1 There are 3 entrances to the site -
a) Main entrance for OPD & IPD,
b) For emergency and
c) At back for services
2) Main entrances leads to public parking (120 cars, 60
scooters) on the left.
3) Roads run along periphery of the site.
4) Seperate parking for emergency.

ZONING
ZONING :
Location of the building should be
convenient to the people it serve i.e the
public zone should be in front . Effective
zoning is required.
Public zone , clinical zone & staff zone.
Privacy and confidentiality are
important.
Security and supervision in the
premises will be necessary.
Emergency should have separate
entrance. Mortuary should be linked
with service road.
Land must not be contaminated.
ZONING (SITE LEVEL)
1. The first one : The most chaotic being public area comprising of entry/exit and
parking.
2. The second : The rehabilitation building which has less traffic.
3. The third : The main hospital building approached by patients , their visitors, the
staff & doctors.
4. The Service dock at the back & basement parking form the fourth zone.
5. Last the beautiful landscaping spread all over the site.
ZONING (BUILDING LEVEL)
The main hospital building has
been divided into 4 blocks:
BLOCK A : Emergency area ,
with seperate gate and
entrance.
BLOCK B : Inpatient
Administration with traffic
restricted to patients admitted
& their visitors.
BLOCK C : Diagnostics and
Labs.
BLOCK D : OPD &
Rehabilitation centre , closest
to parking as OPD has
maximum public traffic.
