2 HISTORY (Most recent) P/2015/0123 P/2015/0036 Corresponding planning application to accompany this listed building application also on this agenda. Listed Building Consent for refurbishment of Hall. Granted DEVELOPMENT PLAN Grade II* listed building located in open countryside. Policies GDP1, PS2 and EC9 of the Wrexham UDP refer. CONSULTATIONS Community Council: No observations Local Member: Notified Wrexham Area Civic Soc: Consulted RCAHMW: Consulted Georgian Group: Predates Georgian period. SPAB: CBA: Consulted Victorian Society: Consulted Denbighshire Hist Soc: Consulted Site Notice: Expired Press Notice: Design of any new elements should be sympathetic and in scale with the existing building and not by moving historic elements to suit a new design. Strongly object to the proposal to raise the first floor central stone mullion window in line with the first floor bedroom. This could damage the historic building fabric and the loss of archaeological evidence of the buildings development. Any extension to an Elizabethan house of this style and status offers difficult design issues. Whilst SPAB accept the current timber framed glazed lean to extension with its classical columns is not sympathetic to existing house, the applicant should be advised to consider some of the possible aspects. SPAB believe new work should compliment not parody the original. Where change or alteration is justified it should be done in a sympathetic manner, but in a style of the current time. Scale, design and approach not acceptable and strongly object. Page 87

3 SPECIAL CONSIDERATIONS Impact of proposed works on existing building: Trevalyn Hall is a grade II* listed building listed as an important example of an Elizabethan Country House. The application has been submitted for the demolition of the garden room to the south west elevation of the building and its replacement with a larger and more functional extension to the In addition, these works require the repositioning of a first floor window. The current garden room extension first appears on a photograph of the building dated 1938, of predominantly timber framed construction with glass roof. The condition of the structure is generally poor having been constructed without an adequate masonry plinth and is therefore showing signs of decay at low level. The junction of the glass roof with the existing building is also poorly detailed and it seems likely that this has caused deterioration in the condition of the first floor windows to this elevation (which are of timber rather than stone in this location). Furthermore, investigations have revealed that the footings of the principal building in the southern-most corner have been partially cut away as a result of previous building works. The applicant wishes to replace this structure, a decision based upon its current condition as well as a desire to create a more functional space. Whilst I am aware of SPAB s objection, the design has been developed from a range of options that have taken account of the particular constraints of the building, principally the position of the window openings and the stonework crest. Consideration has also been given to the architectural form of the elevation and links with the topiary garden, part of the Grade II registered historic garden. A number of design options have been considered ranging from a classical design to a very clinical contemporary approach. The chosen design reflects the strong architectural form of the I consider this to be an acceptable solution. Critical to the success of this scheme will be the quality of the workmanship and materials in ensuring the extension is carefully integrated within this elevation. Further details have been provided including construction drawings of all elements of the design (Roof construction, parapet detail, windows, doors, rainwater goods, location of drainage pipes, vents and flues etc) and the details are acceptable and appropriate for the Conditions will include samples of brickwork, internal and external floor finishes, window detail and external decoration. In terms of the modifications to the existing window, I am satisfied that the alterations will not unbalance or detract from the appearance of the elevation nor will it have any adverse impact upon the internal proportions or features of the room. This slight change will allow for a better quality finish to be Page 88

I am satisfied a number of design options have been considered and that the scheme proposed is appropriate for the building and will respect the integrity of an important listed For the benefit of members an image of the existing and proposed extensions follows. Part of existing extension CONCLUSION South western elevation of existing building The works are acceptable and the design solution will ensure the character of the listed building is respected. My recommendation reflects that the application will need to be considered by CADW. Page 89
