history:

During the end of the 19th century the Dutch Government wanted to create a radio transmitting station that would be able to reach it’s maritime ports in Bandoeng , India.

Previously they had relied on the English and German radio transmitter stations but had to censor their communications. After WWI the Dutch built a radio transmitter station in the middle of an open landscape centered in the middle of the country. The radio transmitter became known as Building A, and the town of Radio Kootwijk was built around it to house all the employees.

Once Building A was completed in 1928, The Queen Mother Emma opened the radio service with the words, “Hello Bandoeng, Do you hear me?” The transmitter station was now the Dutch’s direct connection to India. During WW2 the Nazi’s controlled The Netherlands and used Radio Kootwijk for their own communications. After WW2 they destroyed the radio towers and left the building a ruin. The Dutch rebuilt and reinstated the short wave radio service until 2009. Building A was designated as a National Historic Monument and now is used as a concert venue several times throughout the year, leaving it under used for a large portion of the year.

Re-imagining Radio Kootwijk became the catalyst for use and rejuvenation of a historic landmark. The question then became; How can a decorated shed become a destination that respects the site’s history, the architecture’s integrity, and allows the space to transform into a new use.

Located 80.5km west of Amsterdam and 10km east of Apeldoorn, Radio Kootwijk resides in the center of the Dutch Velwe National Park. The 450 hectare terrain is perfect due to its lact of tall landmasses. A narrow gauge railway was constructed from Assel to the new town of Radio Kootwijk on the Amersfoort-Apeldoorn railway system to help build Radio Kootwijk. A water tower was also designed and constructed to help with the construction.

Building A, the crown jewel of Radio Kootwijk, is constructed out of reinforced concrete due to it’s predecessor in Nauen, Germany. Nauen’s radio building was built with brick and

wood. The heat from the machinery would cause the nails to soften and then parts of the wood roof would fail. Luthmann chose reinforced concrete for his building to combat this, making the building as well as the radio equipment innovative.

The large clearing was maintained over the life span of Radio Kootwijk so the mast field, consisting of six 212 meter tall radio masts, could operate with no physical interference.

The organization of the masts allowed the radio signal to be directed to the correct receiver around the globe.

The Netherlands, a low country with few topographical landmarks. Located on a plateau the site is surrounded by a unique sand plain and pine forest. Over time the forest has encroached upon the radio mast field but recently an effort to clear the area so to keep with the historic significance of the area.

SUN STUDY The land slopes down gradually as you enter the site, creating a large basin. With this gradual slope, the visitor first views Building A at a straight on elevation. Giving the perception of the building a flat view which makes it’s symmetry more captivating. Only one way into the site directs visitors to focus on Building A at the end of the road, making it a true focal point of the site.

FOREST

Located in a usually flat country, this portion of the Netherlands is on a slight plateau. This SITE CIRCULATION area was chosen strategically so that signals could be sent without interference. This added height also allows for the protection of Building A from rising sea levels. While the majority of the country will be underwater, Radio Kootwijk’s location will allow it to be unharmed.

The Velwe National Park is a local favorite for pedestrians, hikers, and cyclists. It contains miles of trails with breathtaking vistas within it’s boundaries for visitors to enjoy.

Superimposing the size of the clearing and Building A onto local and well known sites gave good spatial comparisons.

The clearing is similar in size to the

site approach & phases:

The main axis approach is extremely important to the site. By locating the lobby off the main axis with a viewing deck oriented at Building A, visitors can

experience the pedestrian corridor as was intended by the original planner and architect Julius Luthmann.

Breaking down the total rehabilitation of Radio Kootwijk allows for the continued use of the site into the future.

My project encapsulated the second phase. Creating a destination boutique hotel in the center of the national park.

Which allows for the use of the already restored Building A.

precedents:

Building A is a long and tall volumetric space, similar to a church or barn. By studying other adaptive reuses with similar shapes, an understanding of how to reuse these spaces started to form. Inserting an element into the existing structure became a way to protect while transforming. Not harming the building was a priority and creating a modular system that could be inserted and then removed became essential to the design. Using the existing crane and rail system in Building A gave a perfect method of insertion, while celebrating the industrial history of the building.

hotel study:

Studying different hotel types was essential in finding which type would best fit into Radio Kootwijk. The Robert Morris Hotel in Philadelphia operates as a boutique hotel. With a total of 15 rooms and a common event space, all rooms are rented out with the event space. Spring through late fall every weekend there is an event booked. This model of hotel applied to Radio Kootwijk was the best solution in creating a destination hotel in the middle of the Velwe National Park.

site design process:

Highlighting the main axis while preserving the natural landscape became concept for the site design. By adding layering bulbs along either side of the main axis creates a natural progression to the site. Planting traditional espalier, pruned and trained bushes, to the interior of the courtyard allows for symmetry within the walls while keeping the rest of the site natural.

Separating the lobby from Building A and combining it with a museum and viewing deck allows visitors to learn about the rich history of Radio Kootwijk, while looking at the building through cross bracing of the damaged radio mast from WWII. Creating a visual and emotional connection to the building before they continue onto the interior. Taking the lobby off the main axis and orienting the museum to face Building A allows for a direct view line while not obstructing the main axis pedestrian pathway.

technical review:

Historic buildings were built to last. They are valuable parts of our built environment and history. By reusing these structures, not only is the carbon footprint of construction reduced, but an essential part of historical context is kept for generations to come. One billion square feet of buildings are demolished and replaced yearly. Designing an example of thoughtful reuse allows for a precedent of ‘green’ building practices. Inserting the modular pods, which are each structurally stable, allows the existing structure not to be harmed.

Modular units allows for flexibility in the space. Like a kit of parts having 4 modular types allows for different sized rooms to be added into the space. The smaller unit size also allows for easier travel, installation, and less damage to the existing building and structure. Bolting the units together creates a sound proof and comfortable hotel room.

Inserting geometric patterns into the interior design allows the new pods to reflect back to the historic floor in the main hall of Building A.

final thoughts:

Radio Kootwijk - Re-Imagining a Radio Palace is a educational study on how to create a prototype method of reusing historic buildings. I designed a modular system that can be inserted into an existing building without damaging the existing structure or historic fabric. By utilizing the existing machinery to maneuver the modular pods in and out of the building, I transformed a radio transmission building into a boutique hotel. The modular is small enough that it fits into a single structural bay and could have the potential to be moved or removed. By creating a system that allows flexible transformation, Radio Kootwijk can be transformed for many years to come. Re-using historic buildings is a greener practice and allows for unique and innovative ideas to become reality. Re-use keeps historic buildings relevant, and with them their story. By adding a stand alone lobby-museum to my project, visitors would be able to learn about the rich history that Radio Kootwijk has to offer.

This thesis project was born out of my love for historic preservation, building re-use and recent trips to The Netherlands. Radio Kootwijk is located outside of Apeldoorn in the center of The Netherlands, a town where my grandmother grew up during World War II and Nazi occupation.

By learning about the history of this building and the unique ways the Dutch Re-Use their buildings. Through my research I was able to find and reach out to an engineer, Jan-Willem Udo, who worked at Radio Kootwijk from 1973 until 2005. Jan and his wife still live at Radio Kootwijk in their historic home, built in the 1920s, which was designed for the workers of Radio Kootwijk. Jan and his wife have been a huge asset in collecting first hand information about how the building operated in its prime.

The project was a finalist in the Michael Pearson Architecture Thesis Competition. It was enjoyed by jurors, peers, and professors.
