Upcycle pavilion Vejle

UPCYCLE PAVILION VEJLE Studio 3 Aarhus Arkitektskolen 2018

vandkilen project by Søren Bundgaard Holm, Marleen Stokkeby, Mads Juul Krogshede and Stine Skovbjerg

Created pavilion is orientated in the southeast and north-west direction which follows the walking route of the area. The evening sun is caught from the north-west while the western wind is blocked by the curved brick wall. The glass roof is sloped towards northeast. It opens the pavilion to the picturesque views of the surroundings and is reflecting the ever-changing sky above.

The heatpump is located inside the brick wall and is observable on the street side of the pavilion. Heating pipes are used to warm up the brick wall and bench. As the users walk through the pavilion sliding their hand across the wall, they can feel the heat and that creates additional atmospheric feature to the structure.

In the rain the pavilion comes alive. The water will pour down the two sloping roofs that concentrate the rain to create a wall of water, that the users can interact with, before flooding the pavilion which brings attention to the future challenges of the city of Vejle.

Raised stepping stones keep the users of the pavilion dry and encourage discussion as the people will gather together under the structure to find shelter.

Working in a two persons group is great for small design tasks like Vejle Pavilion.

The first phase, before deciding the three proposals to work further with, we tried to put in as much as what the municipality and users wanted, which in the end turned out to be too much. Both for the program and for the construction phase, since it will be too time consuming and difficult to build. So a thing to bring further on for a task like this, is to keep simple and not to push all the wishes in to a program, but instead go with the most interesting story. Also thinking more about the construction time is essential.

After the selection we divided the five groups into three, meaning 4 persons on each team. It was a great idea, to work on another project or get two other persons in the group makes the project to be seen with other eyes, which in the end made a better project.

Our main focus while building the pavilion was to focus on the timber structure.

UP-CYCLE PAVILION

The primary structure of the pavilion are a series of 9 simple timber frames notched and bolted together to provide a framework which will be covered in glass.

The frames made of upcycled pine wood rest on the masonry wall attached to a timber wall plate.

The frames are made by notching the members to create half-lap joints and secured with a bolt.

The foundation is made by utilizing aluminium window frames that have been cut and weiged down by using farm stones.

UP-CYCLE PAVILION

Since the foundation was not to be made with concrete, we had to collect farm stones.

The stones had to have at least one flat side for stabalizing.

A galge was placed half a meter away from the start and end point of where the foundation was suposed to be. The reason for this was to get a guide for the right distance from the wall.

Using the guide the measures were placed at the string using masking tape, as an indicator for where to dig the holes and where to place the foundation.

The building plate was made of compact gravel consisting of crused concrete, stones and sand. Therefore a jackhammer was a nessesity to dig up the foundation holes.

To create a stable foundation the depth of the foundation had to be 35-40 cm, enough for the farm stone to be partly covered.

The alluminium window were cut into brackets for the rafters to be bolted to.

The foundation holes were tested to see if the bracket had a stable ground and was aproximately leveled, so it came up straigt from the ground. The last adjustment was done when the rafters was placed.

When the pit was aproved the two window frame brackets was placed according to the before mentioned masking tape guides, and then covered in a layer of clay mortar, mixed 1:5 - 1 part clay and 5 parts sand plus water.

The farmstone was the placed in the mortar and the rest of the pit was filled with gravel.

A smaller farmstone was placed on the inside of the finished foundation for the post of the rafter to sit on.

UP-CYCLE PAVILION

The pine timber was first sorted according to size and then all the nails were removed using a crow bar. The nails that couldn’t be removed were hammered in and marked.

A quick template was made on the ground and then raised to determine the right height of the frames and to get an idea of the space it would create.

Using the template as a base, markings were made on the pieces of timber and we were able to quickly fabricate the rafters on the ground.

Due to the varying sizes of the members we decided that a half lap joint would be the best connection to create the frames. The joint would be fastened using bolts making disassembly easier.

To create the half lap joints the timber was scored using a circular saw and then notch was completed by hand chiseling.

After both members were notched they are aligned and bolted screwed together temporarily. They will be bolted together before being erected.

After the all the frames were made on the ground they were carried upright and attached to the foundations.

The rafters were bolted on to the window frame foundation and temporary bracing was added
