Hawkes wins planning for another PPS7 Passivhaus
Hawkes Architecture has won the green-light for this £750,000 ‘county house clause’ scheme in the Kent countryside
The Passivhaus scheme is the first in Ashford to be approved under the NPPF paragraph 55 - a ‘more generous’ replacement for the former ‘contemporary country house’ clause, officially known as Clause 11 of Planning Policy Statement 7 (formerly PPS7).
The 332m² house is arranged in three rectangular blocks set within the frame of a dutch barn.
The lower levels of the house will be clad in English western red cedar while the upper levels will be clad in locally-sourced chestnut vertical cladding.
The house is designed to be completely off-grid for eight months of the year using a hybrid PV system and a log gasification boiler.
This is the practice’s sixth PPS7 house. Hawkes won planning for its first in Kent back in 2011 and for another eco-house in the High Weald Area of Outstanding Natural Beauty in Surrey in 2012.
The architect’s view
The home, located on a farmstead in the rural village of Smarden in Kent has been designed to respond sensitively to the existing established hierarchy of buildings on the former working dairy farm.
As well as having all the usual ‘passive house’ trimmings and levels of performance the proposals include various enhancements to the landscape and energy consumption profile of the entire farmstead setting.
