What we look for in Farnham
We also cover Aldershot and Fleet, close to Farnham. Farnham is about 13 miles from Woking. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Surrey sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
Schools and community buildings around Farnham are usually phased by elevation, with noisy stages in holidays where possible.

England: planning and regulations
Planning in Farnham follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
On residential buildings with a storey 11 metres or more above ground, guidance points to non-combustible external wall materials, and combustible materials are banned in relevant buildings 18 metres and over, so we specify mineral wool systems there.
How is the work programmed?
Work is split by elevation so entrances and fire exits stay usable. For schools, noisy and access-heavy stages are planned around holidays where possible. Health and safety duties under CDM 2015 are agreed at the start, including who acts as principal contractor.
