Building typologies

Diversity can be achieved even by using a single typology as long as plot parameters vary.

Close-grain buildings can produce more entrances than any other building typologies. It is especially important for the mixed use developments. With close-grain buildings, streets and places can be more actived by the pedestrians rather than only cars (Tarbatt, 2012).

Meanwhile, diversity can be achieved even by applying a single typology as long as plot parameters vary. This was proved by the West 8 architects and their bar-code archutectural approach towards achieving diversity with only using terraced town houses (Fig 17).

In general there will be three key close-grain typologies applied in the masterplan: - Multi-family appartment building (mixed use within higher densities) - One flat per floor building - Terraced housing/townhouses

Plot passport

What is plot passport?

Each urban context holds different rules and regulations. Therefore, before any new design is realised, the architects must apply for the planning application to get the approval from local authorities that the new building meets the local regulations. In other words, each plot has its design code that is set within a ‘plot’ passport.

When each plot holds unique parameters, it is possible to achieve a diversity that is not contrived (Fig 20).

Fig 20. Diversity in Sluseholmen, Denmark. Source: archdaily.com

The diagrams (Fig 21) represents the key parameters of a 6m wide two-storey terraced house. General experience suggest that longer and narrower plots are more practical as many more buildings can share the same frontage.

Narrower building plots, no less than 6m for mixed use and 5m for townhouse, maximize activities and efficiency of the buildings (Tarbatt, 2012). However, this is just an exemplar plot passport for the terraced housing.

As an excersize , a plot passport is prepared for a mixed use multi family appartment typology building plot. The table on the right reflects the possible general regulations of the plot within the town core of Drumchapel.

Typology

Typology reflects the density and character of areas, for example, lower density residential area will mostly consist of single-family houses or one-flat per floor appartment buildings.

1. Single family 2. Multi family 3. Terraced

U

Use

Uses depend on the density and character.

For instance, mixed uses and commercial uses are more based within town core and nodes it would not be appropriate where density is low.

Drumchapel

Plot developed by Kristoffer Melville, colleague from Norway

This excersize was done by a colleague from Norway. The rules set out within the plot passport control the design.

However, this does not mean that architects will always end up with the same design for the same plot. The regulations allow for the design to change, but the key parameters must remain in order to maintain the local code and character.

Frontages

Active frontages Active frontages activate the street life and maintain the economic and social generation within town centers. In Drumchapel, active frontages are located within the town core along the new High street and Drumry/Garscadden drive.

The exctract below includes the plots with the set back space from the street edge to provide a space for active frontages.

Non-active frontages Frontages that are not active are usually residential buildings. Even though there are no shops or other services that could generate the street activities, residential frontages can still promote individual identities via planting or fencing as long as there is a reasonable setback from the street edge.

Street typologies

Urban main road Urban main roads are the arteries that connect the neighborhoods and towns nearby. Urban main roads enable public transit and people can reach places either with the bus, their cars or on foot.

Within the town core urban main road becomes the high street where the key services, shops and cafes are located. Furthermore, three of the key special places of Drumchapel are located within the urban main road.

The width of the pavements are wide enough to for pedestrian movement and support of the active street life. In some arteries cycle routes are also included.

Meanwhile, trees are planted on one side of the road in order to increase amount of permeable surfaces but not to overcrowd the streets and provide enough parking spaces for the users.

Overall, not only urban main roads not only are the key routes where people can reach places but also catalyst of public of Drumchapel.

Local main road Similarly to the urban main roads, local main roads are the arteries except that they only connect the neighborhoods within Drumchapel.

Along with urban main roads, local main roads are key public transit routes that enable people to reach places in different transport modes.

Local main roads have only very few places with possible active frontages but the pavements are still kept wide enough for convenient pedestrian movement. In occasional arteries cycle routes are also included.

Similarly to urban main roads, trees are also placed only on one side of the road in order to increase permeable surface area but also to provide more possible space for car parking.

Overall, local main roads are the key routes to reach places between the neighborhoods.

Local street Unlike urban main roads or local main roads, local streets act as routes within neighbohoods only. Basically, local streets are at the bottom of the road hierarchy.

Local streets are important catalysts of neighborhood lives where neighbours can meet each other on the street or people can start their journey.

An occasional tree is placed within the street to give the area character but not to overcrowd the street and the views. Parking lots are also provided only on one side of the street in order to reduce the overcrowding of cars.

In addition, the streets are narrower than urban or local main roads in order to reduce traffic speeds and make the streets more pedestrian friendly. Thus the width of streets is insufficient for busses.

To sum up, local streets are the key neighborhood routes with reduced traffic speeds and enough pavement to enable neighbors to meet each other on streets.

Traffic calming Traffic calming is introduced mainly in the local streets where there is a higher possibility of children playing. The streets are already narrow enough to slow down the traffic but in the longer blocks the curvings of the streets are introduced to reduce the speeds and alert the drivers.

Occasional trees are also placed as objects that attract the attention of the drivers and enable them to reduce speeds. The junctions have wider pavement spaces that enable pedestrians to reach other side of street faster while drivers 32 Gar forced eld St are to drop the speeds.

Flood risk management

‘Urbanisation involves the creation of roads, drains, paths and buildings, creating impermeable surfaces in place of natural permeable surfaces.’ Barker and Coutts, 2016

Drumchapel

Before urbanisation, natural surfaces would normally absorb water (Fig 28). However, the urbanisation involves creation of impermeable surfaces which contribute to faster water runoff rates (Fig 29).

Traditional drainages are designed to cope with a certain amount of water. Howwver, due to climate change, the rainfall rates are increasing rapidly, resulting in overloaded drainage systems.

(Barker and Coutts, 2016).

Drumchapel has a potentially high surface flood risk which occurs due to lack of permeable surfaces. While the frequency and intensity of storms is increasing because of climate change, the new urban proposal should include more permeable surfaces and sustainable drainage systems that could help to reduce the pressure of the traditional drainages.

Permeable surfaces

The proposed street parking lots are constructed using permeable paving (Fig 30 & 31) in order to increase water permeability on roads and reduce the flooding risk.

Swales

SuDS swales are also proposed in the Invercany drive. It will reduce the increasing rainwater rates and provide an attractive characteristic to the area.

The swale will also play an intengral part within Drumchapel’s green network.

Special buildings

Special buildings are the anchor points that provide key social and community services as well as create job spaces. These are the important buildings that represent the identity of Drumchapel’s life, therefore, must be designed in a meaningful and more iconic way.

Mixed use

‘In contrast to privately owned shopping malls, traditional mixed use street buildings are accessed from the public realm providing a backdrop for street life to take place.’ Tarbatt, 2012

Globalization What is globalization?

Globalization is a global movement of people and trade. Good urbanism promotes the identity of the area. However, globalization is running completetly in contraty to responding to the traditions of a place.

There are international or local businesses that aim to promote themselves through a unified model known as an international model. Shopping mall is the most common example of homogenised culture (Fig 39).

According to CABE’s research survey many people want areas with strong characters and identities (Tarbatt, 2012). Places where they could walk in the street and socialize around local services and shops.

Traditional mixed use developments not only can support diversity of services and businesses, it can also activate street life and bring identity to particular places within the town. One of the most popular and successful form of mixed use street is known as the high street.

Station plaza

Drumchapel

Fig 40. Parking lot opening to the station.

Currently, the train station has no welcoming or meaningful gesture. The parking lot is the first place the visitors see when they arrive to Drumchapel (Fig 40).

Therefore, the proposed train station not only sits near the new high street, but it also opens up into a new station plaza. The design was inspired by small English town focal points which include monuments or small clock-towers. These small objects often create more fertile active frontages (Fig 41 and 42).

New market space was inspired by the famous Barcelona’s Santa Caterina Market.

The second design was taken from Tallinn’s new market is. Both designs have iconic characteristics that make the space around them even more powerful.

The proposed market could become the key anchor point sitting at the tip of the most important junction of the town core.

The proposed special place creates a meaningful entrance into the park and stages the library in the highlight. Both, the park and the library connect within the shared space created at the junction.

It is not necessary to have many active frontages around as many of them are already located in previous special places.

Nevertheless, it will still become an attractive and busy public space with a public building at the spot.

Construction

Construction phasing The transformation of Drumchapel involves demolition of the existing industrial blocks and other objects. These massive changes require a phased strategy that would prevent the town from being changed over night. The phased development should enable the town to evolve and adapt to the changes gradually.

The second phase involves the construction and opening of the new plots. In addition, after the road transformations are finished, the new train station can be relocated next to the new high street. The transitional phase between the second and third stage is the planning application for the special buildings.

The urban reconstruction starts with the infrastructures such as roads, railways and services. Therefore, the first phase will include the construciton of the road network and demolitions of the town core and industrial area in southwest. Meanwhile, the transitional phase between phase 1 and phase 2 will include the planning application for the new developments within the vacant and demolished lands.

The final stage involves the construction of the special buildings and special places.

Phase 1 (1 - 10 years) -

Demolition of the existing town core and industrial blocks at the south Construction of the new urban main roads and new street layouts Existing urban main road extension to the A82 Reconstruction of the park layout Planning applications for new developments within the vacant and demolished lands

Phase 2 (11 - 20 years) - Relocation of the train station - Construction and oppening of the new plots within the demolished and vacant lands - Planning applications for the special buildings

Phase 3 (21 - 30 years) - Construction of special buildings - Construction of shared spaces - Integration of the green network

Drumchapel

Sustainable building technology The growing demand for sustainable construction systems has been pushing the technologies to the new levels. For instance, cross-laminated timber (CLT) has recently emerged as an alternative structure for concrete and steel. CLT is an engineered wood product that has been recognized as a sustainable construction system.

Reduced number of deliveries ensure more quiet and less dusty environment during construction. This is especially practical for large long-term development projects such as in Drumchapel.

Also, CLT has high fire proof ratings and, because its timber, provides lighter structures comparing to traditional materials. This is especially practical for taller buildings with poor soil conditions which is a challenge in Drumchapel.

In addition, the use of CLT panels in construction can reduce the number of truck deliveries on site. For example, during the construction of housing in Dalston, East London, the total number of deliveries on site was 111 in comparison 700 if concrete had been used (Ravenscroft, 2017).

Conclusion

Integrate to Regenerate is the realisation of the 2050 vision proposed via plot-based urbanism approach.

Drumchapel is not only more connected with its surrounding towns but also internally. It has numerous character areas that give the identities to different places.

The existing segragated and isolated town core was transformed into a welcoming, diverse and resilient urban hub with mixed use developments that sustain active street use and reduces car dependency.

The phased development will enable steady growth and evolution of Drumchapel and eventually result in a resilient and attractive place to live and work.
