Metal Open Web Internal Floors.

A metal open web floor refers to a floor construction method that utilizes metal open web joists or trusses. This design allows for efficient routing of services and provides cost savings, ease of installation, and design flexibility. https://sipbuilduk.co.uk/sip-flooring


Caberdeck is a structural decking derived from CaberFloor P5, which meets the standards set out in BS EN312: part 5 and BBA-approved, offering additional confirmation of its quality and efficiency. https://sipbuilduk.co.uk/sip-flooring/


TF200 is a breather membrane product offered by the company Glidevale Protect. It is a high-performance membrane meant for safeguarding external walls including roof while construction is happening.

The costs provided are totally indicative and should be used informatively and not part of any detailed budgeting process. How long is a piece of string comes to mind!!! https://sipbuilduk.co.uk/sip-cost/

We do hope however that this helps to provide a picture of what can be achieved with our structures within different budget ranges.

Hampsthwaite | SIP Self Build Dwelling | Hampsthwaite is renowned for its listed buildings and distinctive style, with gritstone being the dominant building material prominently used.

Whilst the client wanted to ensure this style was included, a modern twist was also desired, not just with the building system and fabric, but also the external finish. A mix of Gritstone and zinc to ground, first floor elevations and roof delivered a stunning contrast to this beautiful home set within its spacious countryside acreage.

Internally the Gritstone continued to certain elevations, contrasting against the immaculate, modern open plan space and vaulted ceilings the SIPs system provided. The additional structure the SIPs system required, a mix of thin, strong steelwork and architectural Glulam. Combined the steelwork was easily hidden in floor and wall zones to ensure clean internal lines for the large open plan areas whilst the Glulam provided stunning features in keeping with the more traditional builds within the Hampsthwaite area.

SIP Build UK were appointed to design, engineer and install on site the complete SIPs system, including all internal walls, floors and additional structures such as steels and glulam. All cranage and lifting also included for the duration of the time SIP Build UK were on site to reduce variables and risk on site for the client and overall build program.

SIP Build UK’s understanding of each structural element combined to deliver a stunning home that exceeded the clients aesthetic, thermal and environmental expectations. The use of the SIPs system delivered U values as low as 0.15 without the requirement for additional insulation. The system is also manufactured using the responsible sourcing of materials with OSB and timbers being FSC or PEFC rated, along with the PUR Core having zero ozone depletion and the complete system achieving BREEAM standards of A+.

Giving the client just one point of contact for the complete install of the system, SIP Build UK delivered the dwelling and stable block in just 4 weeks – 1 week ahead of schedule. With the client project managing the build, the use of the SIPs system, combined with the appointment of SIP Build UK, massively reduced risk, variables and potential issues on site.

The SIPs system gave a predictable program time for the superstructure so that follow on trades could be organised exactly when required. The SIPs system wrapped in its breather membrane also took the external finishes off the critical path so work could be completed internally and externally by follow on trades at the same time, again reducing the overall build time of the project.

The aesthetic finish has produced a truly stunning home, the SIPs providing a real wow factor to the open vaulted sections of the build whilst minimising the overall construction depth to both the roof and walls ensuring the internal living space was maximised within this prestigious plot. The overall construction depth in the walls reduced by over 175mm in comparison to traditional methods.

The Specification of SIPs delivered a wow factor with the huge open plan, vaulted ceiling areas and with SIP Build UK taking responsibility for the complete build including additional structures this gave the client further peace of mind knowing that all engineering of the building and its install was the responsibility of the STA Gold standard SIP provider. This combined with the BBA certification of the SIP system also ensured the clients dream home would be approved by building control and be easily mortgageable.

The use of SIPs also ensured that on site variables were dramatically reduced with less trades, materials and deliveries being required throughout the install of the system. This combined with only a 4 week build time on site for the complete SIPs structures significantly reduced the impact on the local community and the immediate environment of the build. Combined with the sustainable credentials of the system, its use ticked all the boxes.
