Holly Park, Islington

Contract Type:  Residential Refurbishment

Client:  London Borough of Islington

Value:  £2,500,000

Holly Park is a unique External Wall Insulation (EWI) scheme that balances the need for energy efficiency with restrictive planning requirements.

Islington Borough Council faced a dilemma over the proposal to externally insulate 269 flats at Holly Park.  The London Red Brick Estate is deemed a heritage site by the local Planning office; however, they were also open to the concept of energy efficiency.  Lengthy consultation between energy consultants, architects and Islington BC resulted in a bespoke design.

Lawtech was engaged to resolve the technical issues and deliver the scheme as Principal Contractor.  Our solution used Weber EWI in Brick Slip, Brick Effect, Silicone Render and Ashlar finishes.

3,000m2 of brick slip at a ground floor level was delivered on Weber’s bespoke grooved EPS for time-efficient installation.  The majority of the blocks were clad in 90mm grey EPS with a cream acrylic top coat.  Architectural details required a further 1,000m2 of brick effect render around windows and 500m2 of rarely-used Ashlar finish insulation in bands across two blocks.

Lawtech also applied InstaBead Cavity Wall Insulation to 623 cavities at a neighbouring estate within the overall project scope.

Delivered under the Energy Company Obligation, the main objective of the project was to deliver carbon savings and reduce residents’ energy bills.  The carbon saved across the estate equates to approximately 5,000 tonnes of lifetime CO2.

Holly Park is a prime example of a great design and build project with unique finishes that could be replicated across much of London’s Solid Wall brick stock.
