I have 2 sets of photos here. One showing a small building lot and the other a much bigger project that is being developed between Daikanyama (代官山) and Shibuya (渋谷), in Uguisudani-cho (鶯谷町).All construction sites have to display this form of notice board showing the work that will be done, what date the construction will start and what permits are in place. The layout and form is standard and is required to be displayed prior to the start of construction.
In this case, the building is going to be a 5 story commercial office building possibly with shops, with a basement floor also. The height will be 15.119 metres. The notice says that construction will start on 1st June 2008 and finish on 31st Jan 2009. Looks like this building either is not going ahead or is being delayed for a long time!
A major apartment project is being constructed in Uguisudani-cho at the moment on the site of some old danchi (団地), public apartment tenements. The land area is quite large and the work is moving at a rapid pace.
It looks from this sign that the new complex will be 17.98 metres tall, be 5 stories tall with 3 basement levels and cover a land area of 4,862 metres sq, creating floor space of 11,005 metres sq.
The apartment blocks, built in 1958, are so well known they even rate their own mention on wikipedia.
Here are some pictures showing the apartment blocks and quite a lot of leafy foliage. I am not sure the new apartment will have so much greenery. http://danchi100k.com/file0125/
