National Homebuilding & Renovating Show, Birmingham - CDI
National Homebuilding & Renovating Show, Birmingham

Our second exhibition of the month is our longest of the year. The National Homebuilding & Renovating Show at the NEC in Birmingham is a 4 day show starting on Thursday March 28th until Sunday 31st March.

We have exhibited at this show for the passed 6 years and we are looking forward to getting back there as we always speak to a large number of people looking to carry out their own projects over the coming months and years.

If you are visiting the show you’ll find us on Stand E187.

Please also keep an eye on our social media pages leading up to the show and also during it for updates on what we are up to there.


Please use the link below for ordering tickets to the show.

We are also doing one of the seminars at the show as well this year.

We will be discussing the benefits of having a concrete upper floor in a house on the 1st day of the show, March 28th, around 4pm. We will be delving into why this should be a feature of your new project.

Please come and have a listen and we’ll answer any questions you may have.


Ask CDI a Question

  • Q

    What are the Lewis Deck sheet sizes?


    Q: What sheet sizes are held in stock for delivery within a few days after order? A: We stock 2500mm and 1300mm sheets.  These are all 630mm wide and 16mm deep.  Deliveries are made via the pallet network directly to site.  The smaller sheets are aimed at small bathroom renovation projects and can be supplied in small numbers via TNT. 2.5* and 1.3m sheets allow for the 100mm overlap to occur over a joist, with joist centres being either 300mm, 400mm, 600mm, 800mm*, 1200mm and 2400mm*. (*2.5m sheet only) For larger projects we are able to produce bespoke sheet sizes if required, please get in contact to discuss other options for sheet sizes.

  • Q

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


    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.


    Is this a question?


    If it is, this is an answer.
