Project: Single storey house extension with garage conversion in Lucan, Co. Dublin.     Date: June 2016 to January 2018      Job Description: Design, Planning, Project Management, certification

Garage conversion in Lucan

The Brief

CK Architecture was approached for the extension of a dwelling in Lucan, Co. Dublin. The dwelling was originally built as a semi-detached cottage, dated from the early 20th century. It was later extended with an additional storey and a detached garage. The new owners were interested with a large open plan kitchen / dining / living area. They were unsatisfied with the dwelling layout at ground floor. The limited budget for the project was a major constraint. The site had a good potential with a total area of approximately 0.05 hectare, a very deep rear garden and space to the side of the dwelling which could be used for an extension. The detached garage at rear represented an obstacle to extend the dwelling. The cost of demolishing the garage was simply unsustainable. The garage had been extended by the previous owner. It had a total gross floor area of approximately 34 square meters, while the dwelling ground floor had a total gross floor area of 60 square meters.

The Project

In order to deliver a design in line with the clients' requirements, all our proposed sketches included for the garage conversion, linked with a proposed extension. The extensions were proposed in different shapes and different sizes. The internal layouts proposed an open plan or sometimes the creation of a lobby with a new access for the dwelling. The final project fully changed the internal layout. The kitchen and dining room were relocated in the original garage area, with the creation of a glazed facade opening on the garden and offering light in the living space along with roof lights. An office / study was created in the existing area of the dwelling, and the original living room is now used as a guest room. One of the challenges was to provide adequate floor to ceiling volume in the converted garage, without undermining the garage roof structure. We preserved 35% of the roof joists and reinforced the structure with collar ties. The clients opted for under-floor heating in the extension and garage conversion. Planning permission was granted in March 2017.

The Construction

The clients experienced a conflict with a contractor who had apparently under-estimated the construction cost. Works started in June 2017. The contractor had agreed to complete the works by September. There were demands for additional funds from the contractor during the works. These demands were partially accepted. The clients, with our recommendations, decided to terminate the contract with their builder, when it became clear that the the works would not be completed on time and on budget, and when the contractor decided to take 2 weeks holidays instead of focussing on the project. CK Architecture prepared all the design for compliance with building regulations and planning permission. 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". CK Architecture assisted the clients to replace the first contractor in October 2017. A new contractor started in November 2018 and the works (except decoration) were completed in January 2018. The clients decorated the dwelling with the assistance of a family member experienced with finishing / decorating works.
