Project: Single storey rear extension in Maynooth, Co. Kildare.     Date: May 2016 to December 2016      Job Description: Design, Project Management, certification

Single storey rear dwelling extension in Maynooth, Co. Kildare

The Brief

CK Architecture was contacted by a family owner of a semi-detached 2-storey 3 bedrooms dwelling built during the 1990s as part of a large, low density, residential development, in Maynooth, Co. Kildare. The clients had requirements similar to many other projects. They were willing to extend without planning permission. The house ground floor was not offering suitable space for reception and enjoyment of the dwelling. The rear garden had a gross area of approximately 87 square metres. The site has a gross area of approximately 218 square metres. The rear garden is orientated South providing a perfect setting to extend at rear. A semi-private waster water drainage pipe to the rear restricted the size of the extension. The clients were looking for an open plan kitchen / dining / sitting areas. They were also willing to preserve an existing living room at front, independent from the new open plan to be provided at rear.

The Project

The rear garden offered diverse solutions to provide the required open plan. Working with the clients, we proposed a selection of ideas with different roof types and different shapes for the proposed extension. The clients opted for a conventional rectangular shape and a double pitch tiled roof. A small utility / boiler room was created. We advised the clients to contact the adjacent neighbours in order to obtain written consent for the removal of an existing boundary wall. The clients hesitated to preserve existing doors between the front and the rear rooms. They also hesitated in respect of the kitchen location. The final decision was to create the kitchen in the middle of the dwelling and to close the set of existing double doors between the front living room and the rear open plan. 2 roof windows were included to maximise sun light in the dwelling. The extension rear facade was proposed with red bricks in order to match the dwelling front facade. The survey and design works started in May 2016. The tender was organised in July 2016.

The Construction

Construction works started in September 2016. The works included for the demolition of an existing single storey structure at rear. CK Architecture prepared all the design for compliance with building regulations and planning exemption. We were appointed to inspect the construction works and confirm compliance at different stages. CK Architecture was also appointed as the PSDP for the project, while the contractor was appointed as the PSCS in compliance with the "Safety, Health and Welfare at Work (Construction) Regulations 2013". Small delays occurred due to the contractor being unaware that the roof insulation fixings were to be imported from the UK. The roof insulation is located above the rafters in order to unable recessed lighting without damages to the insulation layer, preserving the thermal integrity of the extension. the walls were built with a fully filled cavity. Construction works were completed in December 2016.
