“Poppy” Pavilion at Dunham Massey

Posted on by

As we have documented since the start of this academic year, the poppy pavilion project has taken many hours of development and construction to create. Much of the final structure assembly was completed in our store space due to the sheer size of the piece. Alex, Lorena and Nancy assembled of structure in two main parts before transportation to the site.  

 

The group met on a cold and rainy February morning to assemble the pieces at Dunham Massey National Trust park. The poppy was anchored using 3 fence piles which were fixed to the bottom of the structure. The final assembly too a full day and another morning to complete not to mention some frozen hands by all accounts!

The completed structure held its form well and had withstood the recent stormy weather with no problems. The structure along with the other Pavilion projects can be seen on display at Dunham Massey over the coming months.

Well done all involved!

Pavilion Development Continues

Posted on by

The development of the Dunham Massey Pavilions has been slowly progressing over the last two months with many different problems to overcome. Many of the original concepts have changed in scale and style whilst others have remained largely unchanged.

For Alexander Valakh and Lorena Chan the main problems have come from various material tolerances effect on their designs.

The group used the CNC router to cut plywood components for this phase of their design development. The original poppy concept that was made from cardboard and the riveted elements allowed a lot of flex. When applying the same ideas to a more durable and weather resistant material the same shapes could not be achieved. This is where 1:1 design development models come into use.To test the strength of each joint for their revised design the group decided to risk lorenas life lorena to the task. Luckily their design proved successful and despite a few oversights in fixing elements which can easily be rectified, the group can move on.

After the experimental first test in concrete casting, it was nesissary for this group to solve the issues of casting their numbers into each block. For their second attempt they tried using laser cut rubber components with a much smaller block to prevent material waste and save on weight.  Any mould is always worth considering in depth as a badly designed one will cause you a world of problems when you come to remove your cast. This box was simple but constructed well to allow easy disassembly once the cast has cured.  The finished block turned out well with the flex in the rubber numbers allowing for the expansion of the concrete as it sets. Laser cutting this material can prove time consuming and the number required may need to be outsourced due to demand on our machines from all Architecture Students. It is always worth considering outsourcing elements that need to be mass produced as if you are involved in a ‘real world’ project. Costs can often be lower and experienced companies will be able to offer you more specific advice on what you are trying to achieve at 1:1. We’ll be posting more on these project in the near future! 

Garden Pavilions Continued – Learning Curves and Problem Solving

Posted on by

Development of the 6th year pavilion projects is continuing at pace down in the workshop. Test models often bring assembly issues to the surface which Alexander Valakh, Lorena Chan and Nancy Chan have been finding with their concepts. This is exactly why these models play a vital role in design development.  Here Alex has created his outer skin from laser cut polypropylene plastic sheet fixed with pop rivets. This has proved tricky and mid way through assembly it became clear that a more uniform stapled fixing would have been more effective. Lorena and Nancy have spent the last few days fixing components for this concept together. The original concept was to have a smooth curved structure forming the tunnel walkway. As the components were fixed the group found that the curve was un-uniform due to the varying strain between components. Whilst this isn’t exactly how the concept was drawn it has still proved an interesting experiment and may still be taken to the next stage.

Pavilion Project (4)The concrete cast (below) has also had some teething problems with the cast numbers not turning out as refined as the group would have liked. This process will require more thought if it is to be taken forward. The group has found that their choice of aggregate or quantity used may be to blame for the irregular casting around the number details. One thing is for sure it wont be going too far given its weight despite having a polystyrene block inside to reduce the material used!

Garden Pavilions at Dunham Massey 2013

Posted on by

Much like the brief set this time last year students are currently in the concept stages of designing a series of pavilions to be constructed at 1:1 at Dunahm Massey (Read our blog post here). This project was challenging for both staff and students last year and really pushed the boundaries of what the workshops can handle.

This year the project is aiming to be more refined and, with support of workshop staff, come to an effective and ‘speed-bump’ free conclusion!

Alexander Valakh (Below) is working on several sketch models to help convey his project named ‘The Shadow of War’ to tutors in the hope it will be taken to the next stage of development.

To test his theory for eventual 1:1 construction Alex had produced a plywood sketch model in identical fashion to the full size proposal on our CNC. Producing this model has allowed Alex to explore problems he may encounter whilst using this method and has already identified several areas that will need more thought. These issues are not a hindrance to the design process but feed into it and shouldn’t be seen as a waste of time. problem solving through trial and error models are often the best way of refining a design for production.

This group is also producing another concept pavilion using paper to create the sketch model. The flower-like components are created and joined using pop rivets which will eventually form a curved canopy. 

Another (!) concept from the same group involves casting concrete blocks as part of a wall sculpture. This is part of the same brief but is less interactive due to the nature of the proposed site. This was poured yesterday afternoon and is still setting so we’ll hopefully have some more pictures of how that is progressing by the end of the week.
