Harrow Council (with the help of Lottery Heritage funding) employed Dannatt Johnson Architects to undertake restorative work on the Temple. Here is an extract from their website.
When we became involved, the Garden Temple had suffered from vandalism and other anti-social behaviour. This had resulted in smoke and graffiti damage, largely to the rear of the building. Theft of roof flashings had also resulted in loss of slate roof tiles and ingress of water into the temple. In an effort to protect the fabric from further damage, the columns to the rear had been painted at low and midlevel to allow easier maintenance and, ultimately, an anti-scale gated fence was installed to the rear. This damage to the historic fabric was in addition to weathering of the unprotected stonework together with organic growth and urban pollution deposits to the brickwork.
In order to restore and protect this historic feature for future enjoyment, we surveyed the damage and work required to stabilise the fabric and return it to an appearance befitting of it’s value and setting. We oversaw the process of conservation of the existing historic brick wing walls with the removal of invasive plant growth and consolidation of the existing brick work, together with the non-corrosive, low pressure, high temperature water cleaning and minor stone repairs to both primary elevations (front and rear).
Just thought it was interesting to know how much work goes into restoring historical buildings no matter how small or insignificant they may seem to the passer-by.
I followed the road round until I came to the church of St Lawrence Little Stanmore. It was now 10.45am and being a Sunday there was a service going on so I wandered around the churchyard for a little while waiting for the service to end.
