1. Introduction: • What are complex buildings ? Complex buildings are buildings which used for multi-purpose such as residential with commercial. • Residential includes : 1. Single Family, Detached Homes. 2. Duplex, Triplex, Fourplex. 3. Townhouse. 4. Some housing co-operatives. 5. Studios. • Commercial includes : 1. Land Investments. 2. Office Buildings. 3. Retail Space. 4. Storage Units. 5. Industrial Buildings. • Commercial and Residential properties have significant key differences including Building Materials, Codes, Cost, Construction Equipment, and Construction time.

2. Planning and site standards: 2.1. Site requirements:

2.3. Morphological Classification (examples):

• Required entrances( public entrance , entrance to parking and service entrance) . • Location convenient for doctor’s surgery, shops, post office and public phone, bank, school, play facilities, park, public transport, sports facilities. • Integrated with surrounding area. • Clear delineation of public, communal, and private spaces. • Public spaces connected by well-lit routes.

Fig1. morphology examples .

2.2. Public entrance: • It should be a transitional area from outside to inside. • Using high quality materials plus tree planting elements. • In buildings more than 15,000 m2, width > 3.5 m. • Slow down street is required with street signs.

3.3.1: Visitors entrance: • Entrances should be unique and obvious to the eye. • It should be separated from the resident entrance. • 90% of entrances should be directly connected to the parking area, main entrance connected with a drop off. Fig5. entrance example

3.3.2: Resident entrance: • should be able to have unlimited access to the commercial part using elevators.

3.3.3: Services entrance: • Service entrance should be invisible to the public eye. • It should be next to the storages and loading bays. • Required ramps with 1:8 to 10 slope ratio. Fig4. Zoning and relations

C. WCs and emergency:

Fig13. seat details and standard

• Cinemas has separate WCs, isolated from the public WCs. • Two emergency exits in lowest and highest level is required.

Fig17. WCs numbers Fig14. A cinema section example

A. Retails area: Standard area of retails are (Nx1.5)x(Mx1.5) referring to the grid dimensions which used in Malls. With minimum height of 3.6 meter.

It is a must to make a corridor with 1.1 minimum width in the back of my retails. This corridor is used to delivering goods and emergency escape also

B. Retails Entrances: There are many types of retails doors the minimum width is 1.1 metes, for example:

Fig19. Serving corridor example

D. Best practice: • Locate the entrance along the main pedestrian route to the store with maximize the window display area. • Design the entrance in proportion with the storefront, accentuating the height and creating an inviting setting. • . Visually emphasize the entrance by using architectural elements such as projected or recessed walls, signage and more prominent colors and finishes. • Enhance the entrance area by using high quality materials. 9 Fig18.

The dining hall should be very close to the kitchen and bathrooms. If there is a landscape, it is preferred to head towards it. It should be close to the entrance and parking . The width of the emergency exit should be 1 meter for every 150 people. Door width is not less than 120 cm in width, and the window area ratio is 1:10 of the total area.

3.6.3. Atriums area:

3.6.1. What is that? : • is a large open air or skylight covered space surrounded by a building, providing light and ventilation to the interior. • The atrium space type requires flexibility, durable finishes, attention to regular maintenance, and special HVAC systems and lighting.

C. Escalator:

3.7.1. Vertical circulations:

Vertical circulation between storeys requires escalators, featured lifts and stairs designed to stimulate interest. These are usually located in a spacious central concourse or atrium, at junctions or corners and within the large space users.

A. Lifts: • Lift for each 150 visitor (not accurate).

3.7.2. WCs:

Stairs should be near lifts maximum 16 steps between landings and minimum 3 Maximum distance of any location to stairs is 35m. landings are required in legally essential stairways with a storey height of ≥ 2750 mm Landing width ≥ stair width It is preferred in hotels to make stairs width 1850mm for 3 people or 1250mm for 2 people (not preferred).

• Type: Commercial – Residential • Location: Zuidas, Amsterdam, The Netherlands • Program: 196 apartments, offices, parking, a sky bar and retail and cultural space. • Surface area: 75.000 m2 • Start of the construction: 2021 • Architects: MVRDV • Landscape Design: DeltaVorm Groep & Piet Oudolf, Utrecht, The Netherlands. • Engineering: Inbo, Amsterdam, The Netherlands.

Fig66. Shaping the form

The project takes the form of green-terraced stacked boxed that rise to three peaks of different heights, the tallest capping out at 100 meters with the two-story Sky Bar. Clad in a carved natural stone facade, the form has been parametrically designed to allow sunlight to penetrate throughout all of the complex’s 196 apartments, all of which feature a unique floor plan. The corporate surroundings through its reflective exterior façade, the design acknowledges its corporate heritage and visually connects to its immediate neighbors. The inner façade is defined by a series of rugged, stone terraces with large planters, covering the building in vegetation and bringing a sense of human scale to the volume The corporate vs the residential: The XL vs the human scale
