Greensted Colchester prefab identification
Hi, I have looked at a house in Blackthorn avenue, CO4 3QD, the whole street and some of the smaller street around seems to be made of the same type but there are some small variations. https://goo.gl/maps/wwBCtxV8AdsT6Cbo9
Some have dark wood siding on the opposite to party wall, other are painted all over, yet others have some white plastic siding at front and back. The roofs also vary from some sort of tiles to something smooth like metal sheets. All have entrance doors on the side of seemingly standard front extension but some of these extensions have sloped roof others flat.
From looking up a document on this site I saw Hawthorn Leslie being listed for that street but the number of houses given is much smaller than what can be seen on street.
Could you please see if you can tell me whether these houses are indeed the Hawthorn Leslie or some other type? They do not look exactly like the example given here https://www.bisfhouse.com/community/main-forum/various-houses-of-non-traditional-construction/ and elsewhere, more like some sort of mix between BISF and HL but it could just be superficial and they are HL?
The agent is very vague and was guessing it is some concrete build, however I could not find a solid wall other than the party wall, making me doubt his guess.
The vertical corners (stanchions?) of and end-of-terrace are often clad in some white plastic, underneath seems to be some layered wood material, making me suspect the real load bearing material is further below the wood? Do you know if these are known to rust or are the layers of plastic and wood enough to guard it?
How would you classify such house for insurance purposes? Does the flat roof on the front door extension make it "partially flat roof property"? What would your guess of a rebuild cost be (insurance purpose again)?
There are many questions and I'll be happy with any information you can provide.
Hi Marc, Thanks for the detailed answer! I've also found and bought the br152 pdf if someone else has this house and would like me to lookup something in it. Beyond this and your info there seems to be not much else on the net.
I think the first picture may well be from one of the side streets (or "walks") in that neighbourhood.
You're very welcome Dimitar and thank you for offering to share details contained within your document.
As you rightly state, there are very few internet resources available regarding Non-Traditional constructions. As far as I am aware, BISFHOUSE.com is the worlds only website dedicated to Non-Standard U.K housing but we ourselves may be forced to close in the near future due to lack of funding and other reasons.
I'm just glad to be able to assist you whilst we are still in operation.
Best regards and good luck in the future
