Client: Homes for Haringey
Project Value: £80,000
Duration: 4 months
We were appointed as sub-contractor by Mulalley to carry out the upgrade and replacement of Clarence House cladding. Our package of works initially included for the removal and replacement of the UPVC cladding which we designed and developed under the management of Mulalley.
Our investigation works established that Clarence house was a single layer timber frame building comprising of plasterboard, “Rockwool” fibre insulation and UPVC cladding with a mineral splash board to the bottom 1200mm. Our design needed to consider and integrate the following:
- To comply with current “part L building regulations”.
- Accommodate new upvc window and door installation.
- Accommodate roof replacement.
- Ensure all waste and boiler flues were maintained and compliant with regulations.
- In developing the design we provided a two layered high performance insulation board ensuring ventilation requirements were met and surpassing the current “part L building regulations” along with the integration of new windows and roof replacement.
However matters were complicated by the discovery of “wet rot” in three different locations which had not been established in the areas of our initial investigations. We quickly developed a weather protection scheme and method of structural timber replacement to the approval of the Client’s Representative, Building Control Officer and Mulalley to incorporate the necessary eradication and new timber replacement. In Addition to the cladding replacement we were asked to carry out the following works by Mulalley:
- Glass balcony screen replacement.
- External garden fencing and reinstatement.
- Relocation of satellite aerials.
