Has anyone heard of Profitable Plots, land investment?

Profitableplots.com they purchased land in U/K in London,
called Concorde Village,Hounslow, they divide and sell investment plots, then when planning is approved, they sell to a highest bidder for development and the investors get their return. Is this a good investment? Has anyone got
information related to this?

Be careful, I attended their seminar and then did some due diligence thru' the web. Go to www.hounslow.gov.uk - click on "Planning Services", then "GIS", then "UDP Planning Designations map". If you search for the name "Chertsey Road, Feltham" and find the map of the site, it shows that it is a Greenbelt and Nature Conservation Area, not a Brownfield site as they claimed. I joined an online Google Forum called " PlotOwners" and was alerted to this by one of the online participants who is a UK citizen.

A controversial company . Sold Land parcels at a risk and authorities declared it GREEN - never likely to be developed in the foreseeable future. Investors transferred into another project.
Concorde Village is on the edge of HEATHROW AIRPORT (Worlds busiest) and is really brownfield - means that the developer will have to restore and detoxify as necessary as conditions of development should it ever be approved - which one day it may, but maybe not all.
Anyway restoration of brownfield is "cost on" therefore reduces the real value of the raw land in the first place.
My understanding is that Taylor Woodrow has only signed an option for first refusal to develop the land if planning permission is agreed - which means nothing until the land is released. There is a lot of issues regarding aircraft noise and costly sound proofing which once again hightens the risk of making that great profit as the developer has many other land choices without such hastle.
There are moves afoot within UK Government circles to consider legislation restricting such landbank companies so some are moving offshore to carry on the contraversial operations.
