: Thanks for your review. I have exhausted much of the available material relating to the house so should be able to add information where it is available very soon. 

 Certain points you have raised cannot be elaborated on, such as the 2010 arsonists as no further information was released. 

 With regard to some of the other points: 
 * The name of the company that bought the house to redevelop it is within the article already, in the lead and the Restoration sub-section - Westcombe Estates. 

 * From the information I have available, the house has never changed names, other than to be interchangeably known as High Grove and Highgrove House. 

 * It is referred to as an old people's home by the source I used, although I can change that. 

 * The change from a homeless shelter to a luxury housing block was not as dramatic as you may think. Although it was known as a homeless shelter, this was mainly for families rather than individuals living rough.  

 I'll get to work and hopefully this can pass soon.
