Replacing approved tiles with alternatives on listed farm building

[mickeych]

We have full planning and listed building consent for a barn conversion but before starting the main build, we have had to make the structure sound to the main barn by removing the roof and repairing a large number of rotten timbers (all the rafters, the entry and exit beams, a few purlins and one of the king trusses). We have provided an SE report to justify the work to planning in advance (although no other contact to date).

We are now in a dilemma as we find that a large percentage of the original cement tiles are too damaged or in a state of disrepair to refit in line with planning. Permission includes using natural stone slate on the reinstated parts of the barn but not the main barn.

We really would like the contractors to complete the roof and would prefer not to have to supplement the 60% of end-of-life concrete tiles with new concrete tiles in a very different colour. Our preference is to refit the roof with some high quality natural stone repo tiles (already been accepted by planning on a neighbouring barn) without having to wait for a planning amendment to be processed as we would likely loose the builders for 2-3 months. Ideas and thoughts welcome!

You may well need to submit a Variation of Condition (Section 73) application and include samples/details of the new tiles. The determination process can take around 8 weeks and fees will also apply.

 

However and in the first instance, get in contact with the Planning Officer and/or Listed Building Officer.

They were probably that colour originally, and will fade and attract moss, but could be a clash for  few years.

If you can demonstrate that the original tiles are, for example, Redland ' heather' then I don't think you can do better than use the same, even if currently brighter. 

Sell it to the planner as an upbeat proposal of doing what's best.

Or buy reclaimed tikes to match your original

You will need to strip the whole roof.

 

If your budget can stretch to natural slate, suggest this to the planners.

 

I doubt they will be keen on fake stone.  It probably won't weather or last as long as natural.
