Battersea, St Mary Internal Lighting Project Lighting Design Concept Report [R2v1] July 2018

ST MARY S CHURCH St Mary's stands on one of the earliest known consecrated sites on the south bank of the River Thames. The original church was built as early as 800 AD, the present building designed by Joseph Dixon, a local architect, was completed in 1777. The church is built of brick, with stone used for quoins and other dressings. It consists of a nave, rectangular in plan, an apse at the east end forming the sanctuary, and a west tower. The west front has a single storey entrance porch with Tuscan columns supporting a pediment. The tower, rising immediately behind it, is topped with a clock chamber and a small spire. Inside, the whole width of the church is spanned by a flat ceiling, and there are wooden galleries supported by columns on three sides. The nave windows are in two tiers, the upper ones round-headed.

CONCEPT DESIGN REPORT The purpose of this report is to set out the background and strategic objectives of a project to significantly improve the internal lighting at St Mary s Church, Battersea. This report responds to initial briefing information provided by the parish information gained from the parish archives discussions with the parish architect the assessment of case studies showing comparable or other relevant lighting schemes in other churches The client group have clearly set out the fundamental requirements of the scheme which are to provide improved general illumination in the nave and on the gallery improve the lighting at the front of the nave and at the chancel step; which is the focus for much of the liturgy improve the lighting for the choir but reduce the amount of glare produced by the existing spotlights provide more flexibility for the range of community uses of the church including musical and other events The proposals are illustrated in the form of graphic visualisations, CAD drawings and illustrations of typical luminaire types. The report is intended for initial review by the PCC prior to issue to the DAC for informal or pre-application advice. With feedback from this process, these initial ideas can then be refined and developed through detailed design, mock-ups and technical calculations to form a full specification package that can be used to secure formal approvals and obtain competitive tenders for the works in due course.

1. Brief and Approach

BACKGROUND TO THE BRIEF Principal Purpose The principal purpose of the Church is as a place of Christian worship with secular uses including concerts, public gatherings, heritage visits etc. Significance Built on the site of an earlier Saxon church, the current St Mary s Church was built in 1777 by Joseph Dixon. The church is Grade I listed. The location and history sets the church apart as a significant heritage site. The Existing Lighting The existing lighting is poor. The principal source of light is a large Flemish pendant hanging in the centre of the nave which provides a soft glow of light across much of the interior. There are additional flush fittings below the gallery and additional spotlights under the gallery balustrade more light to the pews at the perimeter of the nave. Spotlighting is used in the apse to light the high altar. There are uplights in the windows at ground and gallery level. The lighting for the choir at the front of the nave is particularly poor with spotlights under the gallery focused across the front of the nave. The reading light produced fades away beyond the rear stalls so that the front two rows of stalls, facing the centre of the head of the nave, are almost completely unlit. The Electrical Infrastructure The general electrical installation is considered as unsatisfactory meaning that some remedial works are required for the building to receive a satisfactory condition report. It is known that some of the fuse boards are in need of replacement. It is intended that, where possible, the new lighting should be connected through a new cabling system although care must be taken to minimise the potential impact on the fabric of the building.

CORNERSTONES OF THE BRIEF Worship to provide good lighting for services, including effective lighting for the celebrant and the choir in their stalls, enhancing the liturgy for a worship in its different forms The nave: services with large and small congregations The Chapel where there are smaller congregations and more intimate services. Major festivals and Civic Services where the congregation may completely fill all parts of the church Architectural Features uplighting to the under gallery and main ceiling should be improved both to aid general reading light levels and also to enhance the church s fine interior. Wider Community Engagement to provide an adaptable, flexible and easy to use system suitable for a diverse range of gatherings in the church. New lighting should be suitable for liturgical and other uses, supporting and encouraging wider public engagement with the building for exhibitions, concerts and community events. Safety There should be safe and effective lighting for the staircases, entrances and steps Controls The lighting controls should be reliable, flexible and easy to operate

One of the shortcomings of the existing lighting system is the lack of forward facing lighting to the platform step, the choir and sanctuary. We proposed to replace part of the hanging chain of the central chandelier with a slim rod that has a set of small spotlights attached to each side.

7. Design Development

RIBA PLAN OF WORK The Royal Institute of British Architects sets out a series of stages of work that apply to construction projects of all types including specialist lighting installations like this one. DESIGN DEVELOPMENT The following assessment shows the progress of this project against those work stages. RIBA 1&2 CONCEPT DESIGN This report provides information to the level normally required for RIBA2: - Concept Design RIBA 3&4 SPECIFICATION AND TENDER RIBA 3 is the level of information normally required for Planning Permission or, in this case a Faculty under Ecclesiastical Exemption. RIBA 4 is an additional level of technical information required for accurate tendering purposes For projects of this nature and scale it is normally more cost effective to combine RIBA 3&4 works into one package. RIBA 5&6 IMPLEMENTATION AND HANDOVER RIBA 5 is the installation stage where the physical and electrical works are carried out. RIBA 6 refers to the final adjustments of the scheme including focusing and scene setting.
