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.


A frequently used type of timber flooring is the 22-millimeter tongue-and-groove chipboard, also known as P5 grade. This structural timber board is popular with builders and contractors due to its ability to withstand exposure to moisture. The 22mm thick chipboard flooring, with its tongue-and-groove edges, is commonly installed as a floor surface.


Tyvek breather membrane, is a durable and water-resistant membrane used for the protection of external walls and roofs in construction.

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!!!

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

When a 1920’s brick house on a site that sloped down to the River Nidd in Knaresborough came up for sale, one of the locals moved a step closer to his dream of creating a Georgian style ‘gentleman’s residence’.

Working with PA Design, also based in the town, the pair planned a stunning six bedroom property which took advantage of the surrounding views. What could have been seen as a challenge became a key feature as the slope on the land was incorporated into the home’s overall design and helped create a two storey property which expanded to three at the rear.

Early in the project they chose Structural Insulated Panels (SIPs) as their preferred build method because a watertight structure could be constructed quickly, drastically reducing the time on site by around a third.

The design included a basement level swimming pool, games room, additional garages and a bar looking from the back stone portico terrace down to the River Nidd.

The ground level includes a large open plan kitchen and family day room, a library, formal dining room, sitting room, living room, utility room, butler’s pantry and a study which can also be used as the sixth bedroom. The upper floor houses the master suite and a further four double bedrooms.

Architect Steve is a fan of SIPs: “It’s taken us in the UK a while to catch onto the potential of SIPs but they’re definitely the future of self-build, they’re very versatile, a quick system, and I’m a real advocate.”
