The Brief
In November
2016, CK Architecture was contacted by a family, owner of a semi-detached
2-storey 4 bedrooms dwelling, in Churchtown, Dublin 14. The house was
originally built as a 3 bedrooms dwelling later extended to side. The clients
were willing to extend at rear in order to enlarge the dining / living
area of their home. The family was also in need of an attic conversion
to provide an additional bedroom in the dwelling. The property
includes a large and deep rear garden that could easily facilitate
the construction of another extension. The house had a gross floor area of approximately 141
square metres. The property site has a gross area of approximately
386 square metres. The rear garden is orientated North-North-East.
The clients were also interested with sunlight improvement from the
rear area of the dwelling at ground floor. The attic space height
was low and represented a challenge to provide sufficient headroom
for a new bedroom within a new third floor in the house. The existing
2-storey extension and internal modifications had to be considered
and taken into account.

The Project
The design included for a double
pitch single storey extension to rear, with roof windows collecting the Eastern
and Western sun lights. The ground floor extension, with a total floor
area of 30 square metres, provides a large open space forming
a kitchen, a dining area and a sitting area. The existing kitchen
units were replaced and a utility room was created. The existing front
lounge was separated from the rear of the house providing an independent
and private room to be used independently from the open space. Some
of the existing extension steel beams were preserved as well as large
columns providing necessary structural support. The attic conversion
could not create the required headroom of 2.4 metres within 50% of
the floor space, as necessary for air quality in a bedroom. The proposal
included for a small heat recovery ventilation system to provide adequate
air exchange and air quality in the third floor, which also included
an ensuite bathroom. An engineer was appointed to design and
certify the heat recovery ventilation system. The attic space headroom was increased with a
dormer window located within the existing roof rear slope. The new
third floor has a gross floor area of approximately 25 square metres.
The dwelling large landing area allowed for the provision of comfortable
stairs to access the new third floor. Planning permission for the
dormer window and the rear extension was granted during June 2017.

The Construction
Construction started in October
2018. The works included for the replacement of internal doors using
fire rated doors necessary for compliance fire safety standards
and regulations. A soakaway was created in the rear garden for compliance
with the greater Dublin code of practice for drainage works. An
engineer was appointed to design the soakaway and organise percolation
tests. CK Architecture prepared all the design for compliance with
building regulations and planning conditions. CK Architecture was
appointed to organise the tender, 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". Two tender
procedures were organised due to the first appointed contractor
resignation prior to start of the works. The first appointed contractor
apparently resigned due to miscalculation within the approved contract
price. Construction works were completed in March 2019.
