Start Date: 01/02/2019 End Date: 01/04/2019 Duration: 2 Months

Planning Req:
Not an AONB or conservation area – Permitted Development granted by Adrian Walker at Coltswold DC

EWI System provider:

60mm EPS insulation boards with bespoke Permarock brickslip finish to front elevation with replication of quoins. (NB – first sample photo below we requested to be adapted during installation by having rounded corners – plus the Brickslips can be further hand-cut on-site to generate an irregular finish)

Specialist features:
All stone window surrounds and edging will be replicated by using a specialist reproduction firm (Build-Lite)

Side and rear elevation:
In order to emulate the existing finish – this will have a slightly more roughcast finish with a 3mm grain texture (standard texture is 1.5mm grain). See sample colour below
