Preparing the details plan
•Urban details
• Lots patterns
•Set backs
•Building mass
•Urban codes
Preparing the master
plan
• Study of urban design consideration
• Case studies
• Design alternatives
• Land use plan
• Road network , pedestrian movement and public spaces
Data collection
• Selection of study area
• Site analysis
• Preparation of the project program
Urban
process :
Introduction
: The importance of the site drives from being linked with king Abdullah Road ,
As well as its proximity to KSU , DQ , Historical Irgah city . In addition The site
is characterized by the natural features of wadi Hanifa . During the initial
survey of the study area it’s noticed that there are urban problems such as
random planning , the absence of regulations in addition to the incomplete
facilities . There for . It’s most important to establish a clear vision to the
development of the area based on comprehensive urban design process .
Goals and overall objectives of
the project: 1 – To identify the urban problems in the study area and resolutions .
2 - To improving the area by raising the aesthetic value .
3 –To Enhancing the environmental and sustainability aspects .
4 - To raise the value of the region economically .
5 – To add character to the area .
6 - To connecting the area in a better way .

Irgah valley . And to the west , The site is
surrounded by high voltage Electrical Towers .
Old Irgah is an ancient town was known

The study area is flat land . It is surrounded by Hanifa
valley which has a beautiful topography & natural
elements
Riyadh climate is characterized by an extremely hot in
summer and cold in winter and it is characterized by low
humidity throughout the year about (40 – 49 ) %,
especially in the summer, the great difference between
temperatures during the day and night. The rate of
rainfall is between 10 and 13.1 centimeters .

The study area can be divide into three conditions :
1- Old building
2- Modern building ( less than 5 years old ) .
3- New building ( less than 1 year or under construction )

The majority of the buildings are 2 levels . There are
some higher building like the schools & hospital .
Most of building in the area is made of concrete and
there are few of buildings have
The most useage in the area is residential then
the utilities . And very little commercial or mix
use to serve the area .

Preparing The Master Plan Opportunities and Constraints :
Opportunities Constraints
Visual link to Old Irgah Built buildings
Physical Link to the surrounding Hnifa
valley
Land prices
Rise the commercial use in the area Hot weather of Riyadh city
Suitable area for recreational use The possibility of reducing the privacy
of the residential areas
Physical Link to the current residential
area
Gathering the governmental uses
Creating new character to the area
Urban design principles and consideration :
1- sustainability : A- Using Solar power to generate electricity : all buildings will be covered with solar panels & using the new transparent solar technology in windows which directed to the sun
B- Water treatment & reuse : All the buildings will have water treatment systems which will filter & reuse the gray water in toilets or in plantation then send the black water to the city water treatment plant.
B- Using zero emission transportation : The transportation for the developed area should not be producing CO2 . The area users will using electrical buses , moving walkway , bikes ,
2- safety : Using a safe movement system which solve the issues of the pedestrian , handy caps , bikers and vehicles interaction . By separated lanes . Speed reduction , cross lines elements , etc.
3- Social: A- Maintain privacy B – linked community
