20 Year Old Lewis Deck on a New Self Build

We often get asked by potential customers what the life span of our Lewis Deck system is and how long do we expect the galvanised coating to last on the deck.  Well, very close to our offices in Co. Durham we've been dealing with a customer over the last few years who can help us prove to people how long the steel actually last for.  Read More

Triangle House, West Sussex.

It isn’t very often that you get involved in something truly off the wall and out there. With this new timber framed “triangle” shaped house in West Sussex we certainly had that. Due to the shape of the site, the proximity of a railway line to the rear of the property, and not to mention … Read More

New Timber Framed House, Cheshire.

When looking at different forms of structure for new properties there are a few key differences when using Lewis Deck with timber frame compared to other structural forms. Timber framed houses require the upper floor (s) of the building to provide wracking to building. Essentially this means that the floor acts to prevent the building … Read More

FastSlab Renovation Project, Hampshire

This project in Hampshire was a pair of semi-detached houses that were getting the full refurb treatment. The ground floors were suspended timber floors that were old and damaged.

AVRO, Manchester. Listed Mill Building.

It’s not everyday you get a phone call from an architect asking for help on a grade 2 listed mill building, but that is what happened to us back in April 2017 when Stephenson Studios contacted us with a problem they were having with floor to ceiling heights on their Brownsfield Mill project in Manchester. … Read More

Timber Frame Self Build, St. Albans

The Blue House with Durisol ICF Blocks

Front if the Blue House
One of the more interesting aspects of working with self-build projects is the varied and, at times, very different approaches that are taken when it comes to the design of a new property. This property is no exception. Built on a self-build development site at Graven Hill in Bicester, where every property is different, it … Read More

Traditionally Built House, Rugby

Rear of House
One of the questions we constantly get asked at trade shows and over the phone is “Can we use Lewis Deck on traditional build or does it have to be on a certain type of build method?” The answer is it doesn’t matter. The only design element that we look for is what is the … Read More

Initial project meetings first started in early 2008, the clients owned a small cottage on the site which had been extended several times during the 80’s and had permission to make further adaptations.

  • Q

    Why don't my Lewis sheets interlock like they do in the video?

    A

    Q: Why don't my sheets interlock like they do in the video? A: The sheets have two sides (one printed, one plain), the dovetails on either side are different widths, it is then necessary to alternate the sheets print up and then print down.
