This interesting project involved the construction of a large, new-build 'Pool House' alongside the existing swimming pool. The pool already had a large enclosure and so the building design was modified to match the shape of the enclosure. The architect’s design reflected the brief for the house to have a 'Scadinavian feel', both in shape and materials. Additional requirements were that the building must heat to room temperature very quickly (when not in use it would not be heated). This and the inclusion of a powerful sauna and sunken hot-tub required a high level of design, particularly relating to the electrical supply. Radiators and underfloor electrical heating ensured that the main areas could be brought up to temperature very quickly. In addition to the full construction and fit-out, we were also involved in the final finishing details, through to the fitting of the bespoke bar As well as the Pool House, JK Construction were asked to construct a bespoke 'Garden Library'. This was built using additional insulation and an internal heated floor, which again allowed for rapid heating to a comfortable temperature. This building involved significant additional joinery work to a high standard. Highlights: New-build Pool House with support foundations and full structural works. Bespoke design to match existing shape of pool enclosure – involved complex roof design and construction. Oak bi-fold doors and Velux electronic roof windows. Full provision of new services including: electrical supply and distribution, electric underfloor heating, hot/cold supplies and drainage. High design requirement for finish: Italian tiling throughout, Scandinavian internal structure and finish. Installation of Sauna, sunken hot-tub, shower room /toilets. Bespoke hexagonal outdoor library.

This project involved the construction of a basement to create a two-story 'Granny Flat'. Initial works included fully supporting the existing detached property, then excavation with full temporary works propping. Difficult access presented an additional challenge for soil removal. Major structural support was required throughout as all sections of the new floor were located in the main support walls of the existing property.

This project in Shepherd's Bush was based on a clear design-led premise: To allow the maximum possible light into a lower-ground/partial basement flat. The aim was to create a spacious, modern design, combining openness with privacy. Challenges included the major structural/basement works with close surrounding residents in a quiet residential area and keeping good relations with neighbours during the works. We were able to work closely with both the clients and their Architect Ben Smith, to deliver a beautiful new flat to a demanding specification. Principal works included: Extensive structural works and basement excavations: Substantial underpinning throughout. (approx. 40m²). Construction of a substantial extension (approx. 40m²). Creation of outside garden patio area. This required underpinning of boundary walls to create a relaxing area bounded by large-scale glazing units.
