7. Prior to the commencement of development on site the developer shall submit revised plans and elevations for the written agreement of the planning authority (Conservation Officer) detailing: (a) Hendrons Building — Protected Structure Windows In advance of the ordering or fabrication of the window package, the developer shall submit the following: 1:20 plan and section record drawings of the existing glass block window arrangement on the principal elevation, in order to inform the proposed new window arrangement. Two options for the new windows on the principal façade of the protected structure, (where it is necessary to remove the existing glass block windows to facilitate clear and unobstructed views from the interior of the protected structure as follows). These two options shall be assessed by the Conservation Office for their written agreement: (i) Crittal style steel windows with a horizontal emphasis as indicated on the latest elevation drawings submitted. (ii) Alternative new steel multi-pane window arrangement to reflect the proportions of the glass block windows (panes are circa 200 millimetres x 200 millimetres), which are an intrinsic part of the architectural character of the Protected Structure. Opening lights shall not appear as wider sections in the composition — this applies to both the (i) horizontal window arrangement or (ii) multi-pane window arrangement. Revised drawings showing the position of the new windows within the existing openings reflecting the present arrangement i.e. close to the plane of the front façade, rather than within a deep reveal. Wall Elevations — wall fabric/concrete and render repairs. In advance of executing any fabric repairs to the Protected Structure, the developer shall submit 1:50 marked-up elevations indicating all proposed conservation repairs, accompanied by a detailed schedule of conservation repairs to the façades of the Protected Structure including glazed extension at roof level of the Hendrons Building. In advance of construction of the glazed extension at roof level, the developer shall submit: Revised 1:50 plan, section and elevation drawings of the revised form and position of the new extension at roof level to reflect the symmetry of the principal elevation of the Hendrons Building below i.e. the top floor extension shall have a set-back of the same dimension (circa 1300 millimetres) from both of the side walls of the Protected Structure, rather than extending beyond the side wall (south) as indicated on the floor plans and on the elevation drawings. (b) Boundary Wall — Protected Structure Detailed conservation specification for all key aspects of repair and consolidation works to the historic boundary wail, including additional areas of repairs/reconstruction that come to light through removal of vegetation and further opening up/investigative works shall be submitted. Detailed method statement and revised drawings for any proposed further opening up, consolidation, repair, underpinning and strengthening of the boundary wall (in addition to proposed details indicated on structural drawing M086-TCE-Z0-00-DR-S5-8 Rev. P02 Plan drawing indicating all locations where ’localised’ underpinning of the wall is required, and where galvanised steel column, 2.2 metres x 0.75 metre deep RC pile cap and 130 millimetres diameter mini piles are required to support the boundary wall). Excessive destructive interventions shall be avoided. Revised temporary propping proposal to reduce the potential adverse impacts on the boundary wall shall be submitted. In the interest of clarity and the transparency of the record drawings submitted, the developer shall submit revised drawings that clearly indicate/identify all dimensional alterations that have been made to avoid the 0.5 metre pinch point (increased to 1.2 metres) between Block C and the rear face of the boundary wall - revised dimensions indicated by ’bubble’ revisions and/or contrasting colour of text. (d) Samples The developer shall invite the Conservation Officer to inspect samples of consolidation and repair of the historic boundary wall in lime mortar, and samples of wall repairs to the Hendrons Façade.
