Toronto is a city of crystalization.; in Toronto, old building's facades are being preserved for new buildings. This phenomenon of preservation makes people connection present with the past. Also, they are the heritage that the city has left us. Those facades are not only a history; they are also a witness of time and records of city iteration.
SPADINA HOTEL is a redesign of the 460 King St exsting buidling. The design go through preservation, connection and crystalization. The facades and exsting structure are perserved. The design uses a public interior "street" to connect and make an addition to the two main streets of King and Spadina. And that interior "street" also connect to the addtional structure. The design bring new life to this historical building and turn it back to the function of a hotel, and the hotel will be a crystal that will witness the past, present and future of city of Toronto.
EXISTING BUILDING ANAYLYSIS
Toronto is a typical North American metropolis with architectural influence from both British and American; the city was soon filled up with modern office towers and condo buildings due to the increase in population. However, the city still tries to preserve as many old buildings as possible, making the city a fusion of old and new with self-identification.
The city of Crystallization is the metaphor suitable for this city. In Toronto, old buildings are a foundation for new buildings; they are also a witness of time and city iteration. New buildings are like the crystals on the stone; they are shiny and glamorous, but always respect the stone and the city's history.

Site: Mathare valley, Nairobi, Kenya
Mathare Valley is one of the oldest slums in Kenya; the community struggles to get clean water and access to free sanitation facilities like washrooms and showers. The site also has problems with trash management and river contamination from trash and open defecation. Therefore, there is a need for a solution to those problems.
Mathare pavilions are a group of structures in that each pavilion serves different functions like sanitation, garbage processing, and public space. They all share a prefabricated roof system that collects water and solar power to make them self-sustainable. The prefabrication properties of the building make them easy to ship, assemble and replicate.

Kenya’s population has b n growing since independence with the 2019 census enumerating a population of 47,564,296 people. In 2020, the urban population amounted to 28% of the total population. Further 60% of the urban population is considered to dwe in informal se lements.
Nairobi County has no major water tower and relies on other neighbouring counties within Tana Basin for its water supply which is around 50 Km from the city. Water supply is sti not reliable during drought seasons, also unsustainable land practices near the reservoirs risk its siltation.
Kibera, Mathare and Kangemi are among the areas within Nairobi which were listed to lack space for household toilets and lack land for public toilets. Mathare residents also dispose of some of their waste into the Nairobi River. 90% of the residents do not have a to piped water.

Water, sewage and other po utants drain into the va ey from surrounding co unities & facilities. A e to clean drinking water in Mathare is via water kiosks which charge per 20ltr jerrycan. The prices can fluctuate from KSH 5-20/= depending on the availability of water.It also varies depending on whether the kiosk is private or public(govt or NGO).a

Plastic waste and excrement clog the river
Clean water is usually expensive
Women wash clothes just outside a river polluted with sewage and waste.The rate of drug-resistant infections in the community is high
Most residents pour their excrement into open ditches or rivers, and children may become infected with these pollutants, leading to illness or even death. At night, children may fall into them.
Most of them are simple toilets without water or electricity, which are in disrepair and pose significant safety hazards
Toilets are gender neutral and lack women's privacy space.At night, they may even encounter danger.
No place to wash hands. Toilets is very dirty.
Excrement and garbage can be made into three-dimensional vegetable gardens
Frequent flooding during the rainy season.Most of the rainwater is wasted because there is no place to store it.
Excrement can be treated to become fertilizer.

Flying toilets are frequently used here. Almost a my neighbours use them and the practice is that they are thrown at night. We f that this contributes to the unsanitary conditions in our environment but what do you expect people to do? Toilets and latrines are very few for most of us. In my case the landlord has not put up a toilet and yet we are about five families living on the plot…

Critic: Victoria Suen
Site: 256 Dufferin st, Toronto, Ontario, Canada
SOUTH PARKDALE is a historically vibrant neighbourhood in Toronto; the community is famous for its Victorian buildings, multicultural residents, commercial shops, and restaurants. The site has been used for a new condo development, which stirred protests against the gentrification of the community.
The Parkdale Community Center is a repurposing of the site that can benefit the community instead of gentrifying it. In this project, the main goal is to reconnect the neighbourhood with water, based on the history of a highway that has been built; it creates a mental and physical barrier for the residents of Parkdale to access the lake. The building also considers using functional designs that support the sustainability factor of the building.

As the Aging population grows, there is more need to renovate old houses to adapt to the need for aging in place. Aging in place has several benefits: it is more cost-effective, it keeps the owners engaged in their community, and it gives them a sense of familiarity, which is especially helpful for memory loss or cognitive decline.
The project renovated an old building at 37 Bulwer Street in Toronto, Canada. The project aims to create a safe and accessible environment for the users to stay in place. The program ensures that similar functions are within the same floor and makes sure they are all accessible.
