Of course, if we find enough backers for the City Hall Unit then we will continue with all the other 16 units. We are planning to finish another new unit for delivery every four weeks. Only in the case of the second unit do we expect to need a little more time.

For the first unit ‘City Hall’ we have already finished the instructions and prototype model. The very difficult issue of sourcing all the bricks we need has been solved. To keep the price within an acceptably low range, we have chosen not to use Lego® bricks. The quantities that can be ordered through the Lego® Shop are very limited, so that was not a viable solution for us. Instead, we are using bricks from other manufacturers who can provide us with the quantities we need. The shape, color, and quality is almost identical. Of course they do not have the Lego® logo on the studs, because it isn’t Lego. From the customers of our tank models we are receiving feedback all the time, and they tell us our bricks work well in conjunction with Lego® parts. We agree with their estimation. 

As an additional reward for your support we offer the Ellis Island Unit. This design is also completed and you will receive it together with the City Hall unit if you become one of our first backers.

We have put a lot of effort into the design of the Downtown Manhattan model. We need your support for the very first City Hall unit, to make the dream of the whole block based model a reality.

This is what our designer Adrian says about this project:

In terms of pure parts count, this is my largest creation to date, totaling over 20,600 parts and measuring 135x129 studs (107x102cm). The project began with a request from BlueBrixx to model Downtown Manhattan and after clarifying that they understood the scope of what this would involve, the first step was to solve the geometry for the base in a way that would allow the full build to be split across 17 units while still respecting the angles required for the main roads and blocks of buildings.

After that, the actual designing of each unit was mostly straightforward, though also very demanding in terms of accuracy and detail. A lot of time was spent using Google Maps, switching between Street and 3D views as I progressed street-by-street and building-by-building through the city. The height of every skyscraper was also meticulously calculated for scale.

A further challenge was posed by the many angled ‘off-grid’ sections of roads and blocks of buildings, which was met through the use of trigonometry to calculate the necessary connection points for connecting on-grid and off-grid sections within the tolerances of the parts. While the design was created in a digital format (using LDraw and LPub software), most of the complex buildings and structures were also test-built in physical bricks, as many buildings required complex geometrical solutions and tricky connections which were more efficiently solved through hands-on building.

One further challenge was that of deciding how to deal with the ongoing construction present throughout the city. For instance, I have included the completed Performing Arts Center (next to 1WTC) while the adjacent 2WTC area remains a construction site. While the many large and iconic skyscrapers – such as the One World Trade Center, One Liberty Plaza, and 60 Wall Street (Deutsche Bank) – might be the most eye-catching in the final model, the more satisfying parts of the design process were the coastal areas and many finer details, such as the South Street Seaport (Pier 17), Trinity Church, and the Staten Island Ferry Terminal.

The City Hall unit is a personal favorite with its varied and representative sampling of large skyscrapers, detailed smaller buildings, and foliage; as is the Brookfield Place unit with its off-grid geometry, interesting architecture, and detailed harbor.

I hope you will be able to derive as much enjoyment from these models as I’ve had in designing them.

To give you a clearer idea of the next units, we here present you with some further renderings.

Risks and challenges

Two years ago I would have said: "There will be no problems at all". Today I'm more experienced and I know very well how difficult it has been to find a supplier for our bricks in the needed quantities and quality. But I also know that we have now solved this difficulty with our supplier for the bricks of our existing BlueBrixx models. We have experienced issues concerning such things as delivery times, possible mistakes in the ordering process due to the huge number of different elements we need, and other small difficulties. Of course, it could be that some new problem will arise to create a delay. But in the past we have solved all such problems, and in addition to that experience we have also built some room into our delivery schedule so that a small delay with our supplier, for example, will not result in any delay for your delivery. In each case, we will keep you updated all the time.
