BRAȘOV INTERCITY
HIGH-SPEED RAILWAY STATION IN TRANSYLVANIA
BRAȘOV, ROMANIA
The project aims to create a high-speed railway station in Brasov’s business district to better interconnect the country and encourage the distribution of economic growth. The station will have a structural solution that is innovative, sustainable, and has the capacity to inspire. The structure will give a new identity to the place by recreating the complex geometry of Transylvanian vernacular roofs with contemporary timber construction methods.
The economic development of the country is fuelled by the growing IT and services sectors, with business districts in the leading cities of the country being at the core of this development. However, the neighbourhood and the wider metropolitan area are poorly connected to the national transport infrastructure. The consensus in the country is that the lack of fast and reliable intercity transport connections will hurt the economy in the near future.
A high-speed railway that connects regional cities with the European high-speed network will certainly speed up the region’s economic growth. The development will also help EU-wide policies that seek to replace short-distance flights with highspeed railway services to cut pollution.

Conclusion
Considering the timber construction technologies available today, the hammerbeam roof cannot be seen as innovative anymore. Its symbolic value, however, far exceeds that of other timber structures in the country.
Arguably the roof, a structural component of the building, is the element that connects all the historical events that have unfolded in the hall.

HS1 ► Artefact
1. Dimensions of the components in the Westminster Hall hammerbeam roof are generally consistent throughout the structure. With modern timber construction technologies, a similar structure could be optimised to be more lightweight and use less material.
2. A way to achieve Topological optimization is to implement a treebranch system. Stuttgart Airport has a very legible structure shown above. Even though this example is a steel structure, the principles can be applied to timber construction.
3. The solutions above will both require a 5-axis CNC miller to sculpt the connections.
The pure form of a topologically optimised load-bearing structure can be generated with various software. The one to the left was obtained with grasshopper, (parameters were set to mimic the use of wood).
This 3D model inspired the next step. The models below explore the assembly of an optimised tree structure using made of glulam.
This structural tree is composed of laminated ribbon-like components that are bent to form the branches.
This method ensures that load paths are continuous, connections do not have to be CNC milled and different timber species can be seamlessly layered along the ribbons to locally increase strength.
The structural solution presented here is used to construct the high-speed station of the brief.
The form of the station roof is further informed by the local Transylvanian vernacular architecture.

1.7 Oct 2022 PG14 HS1 ► Artefact
The complex three-dimensional roof geometry of the local vernacular is mainly influenced by two environmental aspects:
Snow
As the roof structure is made of timber and the enclosure of wooden shingles, the snow cover must be removed as soon as possible to slow the degradation of the materials.
Earthquake
Although stone is used for the foundation and occasionally the ground floor, vernacular buildings are mostly made of timber. It is possible to imagine that this material choice was influenced by the considerable seismic activity as well as the abundance of timber in the region.
Shingle Roof
The two environmental conditions above result in a fluid and elegant enclosure system that can adapt to various openings and building extensions. This system inspires and informs the enclosure of the railway station of the brief.
Well-assembled timber structures are more flexible and easier to repair in the event of an earthquake than stone constructions.

Economic growth & Unequal distribution
Metropolitan regions in the former socialist countries of the European Union have seen considerable economic growth in the past decade. However, wealth is far from being equally distributed across these countries. The lack of a high-quality transport network is by far the most important factor that holds back the distribution.

Although Brașov is close to the centre of the Earthquake hazard zone the city is very well protected from major earthquakes by the Carpathian Mountains.
The result of this situation is that some people might ignore building regulations. Old heritage buildings that were not designed to withstand earthquakes are at risk of being damaged in the near future.

Regeneration of a former industrial neighbourhood
The Tractorul neighbourhood has experienced a transition from a socialist industrial neighbourhood to a contemporary business district.
Such business districts are driving the economy of a relatively new capitalist system in Romania. These centres however are poorly connected throughout the country and the lack of fast and reliable inter-city public transport is holding back much-needed development.
Solution
The high-speed railway station aims to better connect important, developing cities in Transylvania with the capital Bucharest and the wider European high-speed network.
Placing the station into the business district will encourage its further development and will attract new employers eager to expand nationally and internationally.

Once the High-Speed Railway Station is finalised, Brașov will become one of the most important transport hubs in the country, as the route will connect important, already existing regional railway routes with the European TEN-T Railway Corridor Network.
Benefits
Increased Competitiveness - Businesses will be able to rapidly expand in the region and beyond national borders.
Foreign Investment - Today there are few foreign companies investing in Brașov. The lack of reliable transport infrastructure makes Brașov one of the most isolated large cities in the country.
Green Public Transport
Brașov has the largest electric bus fleet in the country
The addition of a tramway line that connects the city centre with the high-speed station would further improve its green infrastructure.
Cleaner Air - The opening of a high-speed service will remove thousands of personal cars from the most congested and therefore polluted highways in Romania High-Quality Green Spaces - The neighbourhood will be home to the largest urban green space, outside of Bucharest, in the country.
Tourism - The city and the surrounding UNESCO World Heritage sites will attract much needed-revenue resulting from the increased number of tourists.
Green City
Although Brașov’s ambition to transition into a green city is not codified in policy documents, the city takes pride in being one of the greenest cities in the country.
Last year Brașov organised the second edition of FOV (Green Cities’ Forum). The conference brought together regional, national and European decision-makers and city officials to share ideas and encourage the implementation of green policies throughout the country.

There are many stakeholders who would benefit from a new high-speed station. It would not only increase the amount of new investment into the local economy but also improve tourism in the region. Brașov is already the most visited city (after the capital Bucharest) in the country and the number of visitors is increasing. However, because of the lack of reliable transport systems, the city cannot reach its full potential.
The Romanian Government
The Romanian Government has no current plans to build a high-speed railway, but many existent railways are being upgraded. Nonetheless, various ministers have discussed before, the feasibility of a high-speed railway in order to better connect the largest cities in the country with the capital.
The government will have a central role in allocating funds for the project, and in setting up agencies that have the capability to further organise the project.
Romanian State Railways European Union Hungarian State Railways
The Romanian State Railways company will operate the infrastructure of the railway and the high-speed station in Brașov.
Although CFR has the largest stock of trains in the country, other private or foreign state companies will also operate services, according to European law.
Brașov City Council
The Local City Council will have a central role in assessing and authorising the railway station project.
Although it is unlikely that the city will be able to finance the project, given the scale of the development, the council could help with the extension of the local public transport and the reconfiguration of the green infrastructure surrounding the future station.
The local community
It is important to consult the local community and the wider city population in the early stages of the project. This will help to understand how people travel to and from the neighbourhood, what intercity connections would be the most useful and what facilities and amenities could the new station bring to improve the quality of life in the neighbourhood.
The European Union is currently pushing for a transition from short inter-city flights towards ecologically friendly train services.
The UE will most likely provide a substantial amount of the funding necessary for the construction, as it does for other European-wide infrastructure projects that are beneficial for the entire Union.
The Hungarian State Railways company has a long-standing agreement with the Romanian State Railways. There are multiple train services operated by both companies, that connect important cities between Romania and Hungary. Given that high-speed trains will travel all the way to Budapest, the overall project will have to be a joint investment.
The local businesses Tourists
Given that the neighbourhood is an important business centre, the stakeholders of this district must be consulted to understand how the opening of a high-speed line and railway station can be used to encourage growth.
It is important to understand how tourists would use the new station and infrastructure and plan ahead to mitigate any disruption that the construction might cause.

Landmark & Identity
1. As the front of the station sits on an important axis of the developing neighbourhood, the concourse will become an important landmark giving and identity to the place and acting as a gate to both the city and the high-speed network.

The design of the roof will reflect the character of the local vernacular whilst responding to the needs of a modern high-speed station.
Platform Level
1. As soon as the train is ready for boarding, passengers waiting on the ground floor, under the viaducts will be able to quickly board the train; whilst arriving passengers can walk along the platform towards the front of the station. Passenger flows are thus separated for greater efficiency.
2. Arriving passengers will be able to see the Carpathian Mountains from an elevated position as they reach the front concourse.

Roof Platform
The Transylvanian Roof Geometry
The roof of the station is inspired by the complex geometry of the Transylvanian vernacular.
The roof transitions from a continuous enclosure to separate free-standing canopies. This linear roof is sectioned by corridors that mark the platform access
and interchange zones, thus creating a sense of place.
All corridors are oriented to frame the view of the mountains that surround the city.
HS1 ► Form-finding
Transitions
View Corridor
Intersecting roof geometries are explored in order to identify solutions for the roof. The enclosure has to reflect the various uses within and around the station, frame important views and guide passengers around the station.
The platforms must be able to accommodate the longest train configuration in the fleet. However, 12-16 coach trains will be rare and therefore the end of the platforms will rarely be utilised. The end of each platform is the least enclosed zone. The canopies provide cover to
the passengers along and above the centre of the platforms only.
As we move towards the front of the platforms, the independent canopies are gradually merged and a wide-span roof is achieved.
A view corridor linking the neighbourhood and the Tâmpa Mountain influences the last stage of the form-finding process. The intersecting roof geometries are aligned with the view corridors.

The Transylvanian shingle system is highly flexible. It can continuously enclose a complex geometry thus forming a fluid shape.
Representing a contemporary interpretation of the shingle system, the roof will be covered by solar panels of various transparency.
The light will be scattered by these panels similar to the way it infiltrates a pine forest.
The electricity gained will be used to run various systems within the station
The contemporary reinterpretation of the vernacular shingle system presented allows the fluid enclosure of the station roof.
Tiles of different lengths will be utilised, and were the curvature of the roof is more pronounced the length of the tiles will be reduced.

Because the station is mostly open, modular passenger waiting rooms and staff-only rooms are present throughout the station.
These are insulated, heated in the winter and cooled in the summer.
Services are placed below the platforms and connect to each room from below the floor

Tectonics ► Modular Platforms
The platforms are composed of a series of modular elements listed on the previous pages.
These elements are supported by a concrete and Glulam structure that forms a bridge between the two adjacent viaducts.
There are two types of such structures:
Natural Light
When possible, the modular elements are designed to let as much natural light as possible through the platforms. This is achieved with skylights, openings for the canopy structure, and vertical circulation (escalator/lift) openings.

This section shows the configuration of the roof structure before it transitions into the structure of the front concourse space. The separate canopies are now fully connected forming a continuous enclosure.
The structure of the roof adapts throughout the station.
The ends of the platforms are less used therefore a continuous roof enclosure is not needed. Individual canopies are supported by the viaducts.
Around the centre of the station, the independent canopies are joined and start to form a continuous enclosure with occasional openings.
At the front of the station, the load of the continuous roof is transferred directly to the ground, and a waiting space with a panoramic view is located high above the concourse supported by the same structure that holds the roof.

These drawings show how the edge of the platform connects to the interchange bridge at the front of the station.
The platform edge folds from a flat surface into a parapet. These are welded together and form a continuous bridge that is placed onto a large-scale Glulam structure.
The end of the viaduct has a slope in order to make the stationary trains visible from the ground level.

In order to efficiently organise access and movement within the station, arriving and departing passenger flows will be separated.
1
Passengers arriving with the tram will be able to quickly decide which platform they need to choose.
Passengers will be able to locate the escalator or lift that is closest to their allocated coach prior to the arrival of the train
Departing passengers will be allowed onto the platform after most arriving passengers left the train.
Arriving passengers will walk along the platform towards the front concourse
The interchange bridge will allow passengers to easily change platforms if needed, and arriving passengers will be able to admire the mountains from this level of the station

Given that the station is located next to a new residential area it is important to reduce the level of noise generated by the trains.
In order to reduce direct noise from the station towards the residential areas, side panels will be placed along the two sides of the station.
In order to reduce the noise level for the passengers waiting for the trains, the underside of the viaducts is fitted with custom-made panels that have a jagged surface.

1 Front approach The
front face of the station acts as a gateway to the city and the European railway network.
Passengers (including the workers from the business district) will use this approach as the main pedestrian access point.

CONSTRUCTED FUTURES 2023
At the center of Unit 14’s academic exploration lies Buckminster Fuller’s ideal of the ‘The Comprehensive Designer’, a master-builder that follows Renaissance principles and a holistic approach. Fuller referred to this ideal of the designer as somebody who is capable of comprehending the ‘integrateable significance’ of specialised findings and is able to realise and coordinate the commonwealth potentials of these discoveries while not disappearing into a career of expertise. Like Fuller, we are opportunists in search of new ideas and their benefits via architectural synthesis.
As such Unit 14 is a test bed for exploration and innovation, examining the role of the architect in an environment of continuous change. We are in search of the new, leveraging technologies, workflows and modes of production seen in disciplines outside our own. We test ideas systematically by means of digital as well as physical drawings, models and prototypes. Our work evolves around technological speculation with a research-driven core, generating momentum through astute synthesis. Our propositions are ultimately made through the design of buildings and through the in-depth consideration of structural formation and tectonic. This, coupled with a strong research ethos, will generate new and unprecedented, one day viable and spectacular proposals. They will be beautiful because of their intelligence - extraordinary findings and the artful integration of those into architecture.
The focus of this year’s work evolves around the concept of ‘Constructed Futures’. The term aims to describe architecture and as such fundamentally human future as the result of the architect’s highest degree of synthesis of underlying principles. Constructional logic, spatial innovation, typological organisation, environmental and structural performance are all negotiated in a highly iterative process driven by intense architectural investigation. Inspiration for inherent principles of organisational intelligence can be observed in both biotic and abiotic systems, in all spatial arrangements where it is critical for the overall performance of the developed order. Through the deep understanding of constructional principles, we will generate highly developed architectural systems of unencountered intensity where spatial organisation arises as a result of sets of mutual interactions. Observation as well as re-examination of civilisatory developments will enable us to project near future scenarios and position ourselves as avant-garde in the process of designing a comprehensive vision for the forthcoming. The projects will take shape as research based imaginative tales, architectural visions driven by speculation.
