See appendix
This is a glazing system that is ideally suited for protected structures due to the fact that when installed the glazing reads as single pane glazing. Cozyglaze are one of the leading specialists in the country for this kind of work. This specification also results in a uvalue of 0.4 compared with the current estimated reading of circa 5.6- a significant improvement. The windows are essentially in reasonable condition and will only require some small localized repairs. It is then intended to prepare, sand and repaint in two coats of water based paint and adjust as required the existing sash weights. -as per schedule see appendix
All works to be carried out in line with best conservation practice as outlined in the department of culture, heritage and the gaeltacht's 'windows, a guide to the repair of historic windows’. Relocation of front door: our client is very keen to re-instate the front door back to its original location at the front of the house on the east elevation. Evidence which confirms this location has been identified initially by word of mouth but more recently by way of documents sourced from the irish times archive. See appendix
This is a series of advertisements for the sale of the property by jackson stops & mccabe the first from 1920 which indicates in its description of the property the following sentence; 'outer tiled hall with mahogany glass doors to inner hall' a separate advert contained a photograph of the front of the house, (see attached advert from the irish times ad of sept 25th 1943 ), which clearly indicates that the main entrance was in this location at that time. Further evidence is provided by the repair to the brickwork visible under the sash window (photo g). It is also noted that the adjoining property at no 1b ailesbury road ( currently the pakistani embassy ) is of similar vintage with an almost identical front screen and brick detailing. The existing door and frame are in reasonable and it is proposed that they are carefully removed from their present location, refurbished in line with best practice and repositioned to their original location on the east elevation. Relocation of sash window (w

To the opening left by the removal of the front door screen. Detail survey of this area, and the fact that the cill position lines up with the adjoining window and the decorative brick string course would indicate that there is a high probability that this was its original location. It is proposed that the opening would be carefully infiled with recycled bricks salvaged from the east elevation, bedded in lime in a bond to match the existing. Re-instatement of outer hall (g
Part of the proposed works would include for the re-instatement of the front hall, an area currently being used as a bathroom.
