How to build kitchen island wooden extension over stone?

Hey guys. Just trying to find some ideas and hopefully dimensions that preferably won't break the bank on the best option to add some sort of wooden waterfalled edged benchtop that would become an extension over the backside of my current stone island benchtop. I've attached photos above of the idea I'm going for and my current benchtop to hopefully get some advice from anyone reasonably skilled or DIY'rs who've done similar on the how to, how hard and how much I'm potentially looking at to get this done. Appreciate anyones

Looks like a great project to tackle @RUNNAMUKK1 now that you have built your terrific pool blanket box.

Sorry for the delay, but I'm sure one of our resident Bunnings D.I.Y. experts @EricL will be keen to assist as soon as possible.

Let me also tag a few experienced members in @homeinmelbourne, @tom_builds, @redbournreno and @Remarka6le for their thoughts on how they would embrace this challenge.

That second example looks more like Laminate or Melamine than it does wood, if that's the case then it would be as simple as showing the images and desired dimensions to a wholesaler to cut and then bracing the pieces together / to the bench / to the floor if you're confident enough with your ability.

If we're using the second example as a guide and we were wanting wood, my approach would be to get get lengths of the desired wood cut to size for all three sides at Bunnings, take it home, sand, lightly bevel edges, stain to the desired darkness, clear finish, assemble over bench, secure all three sides to bench and floor. Cost would be for Wood, stain, clear coat and materials for however you're securing the bench, I don't see it as being a super expensive project.

Hello @RUNNAMUKK1

My apologies for the late reply. If you have the necessary tools, it is possible to build this table from the benchtops available at the store. However, if you are after a specific colour and finish on your benchtop it will need to be ordered at the special orders desk. If for example, you use Think Timber 2400 x 600 x 32mm Beech Benchtop, it's just a matter of cutting the panels to the height and length that you need so that it is slightly larger than your current island.

The easiest way to join the benchtops would be to use an ordinary butt join and drill some holes using a Kreg Pocket Hole Jig 310. This will allow you to drill mounting holes that are technically out of sight. You can use either silicone or small angle brackets attached to the floor to secure the extension so that it will not move. If you wish to add additional support, I recommend putting angle brackets where the benchtops join together.

I've placed a sample sketch below to give you an idea of how it can be put together. Please have a look and tell me what you think.

If you have any questions about the assembly, please let me know.

Gorgeous idea @RUNNAMUKK1

I actually have n o idea how to make that happen. I suppose the first big decision is whether you want real timber with the rustic effect like your first photo, or if a wood look laminate will achieve what you want. Because the method of fixing would be different between the two materials.

Also the point where the existing benchtop meets the new timber section would need to be joined well, or it will probably get a bit yucky with all the kitchen water and crumbs etc. Since you have a sink there, I would recommend the slightly raised version of the first photo, resting above the existing benchtop.

Lots to think about but I would suggest you ask your local handyman/carpenter/cabinetmaker for advice.

Welcome to the Bunnings Workshop community @Asad. It's sensational to have you join us, and it's brilliant to see you took inspiration from this post.

You've done a wonderful job, and I trust the extensions add some much-needed bench space. Would you mind showing us how you attached the extension? I'm sure that would help anyone wanting to replicate your project.

We look forward to hearing all about your projects and plans around the house and garden. Feel free to reach out anytime you need assistance or have something to share with the community.

Well done.

i could have directly installed supports in front of bench but to hide i just drilled some holes and slided from inside of cabinet.approx 32mm thick wall of cabinet and my extension was not heavy so i though will serve purpose and hide brackets.

Hi @EricL

A question on your suggestion. You said to include small angle brackets on the floor so it does not move. As per pic it looks like the lower part of bracket is under the waterfall? so waterfall will sit on bracket ? depending on the bracket size for eg if it is 2 cm then the waterfall will sit 2 cm above ground on brackets ?

JacobZ

Hi @Savya01,

If the waterfall piece sits on top of the bracket, then yes, it will sit up off the ground by whatever the thickness of the angle bracket is.

You could either cut some small rebates in the bottom of the panels for the angle bracket to sit in, or just turn them around so the horizontal leg protrudes out from the timber panel. The downside to turning them around is that they would be more visible, but if you are ok with this, it is the simplest solution.

Let me know what you think and if you have further questions, please don't hesitate to ask.

Id like to do something similar to this but am looking to go L Shaped so I can have extra space at the end of the bench. Any suggestions as to how to make this sturdy?

JacobZ

Hi @MummaJ,

Welcome to the Bunnings Workshop community, it is fantastic to have you with us.

Assuming you mean L-shaped, in that it wraps around the kitchen island and extends the surface area on both the short and long sides, we'd need to consider the island's size, as there may need to be a join at the corner. If there is a joint at the corner, then this would be the most important spot for reinforcement.

Things like vertical legs and brackets, as in @EricL's example, would still be essential, but with the join at the corner, you may need to use things like benchtop joiners and plate brackets to ensure the join is sturdy. If there is any flex at the corner, this could lead to issues, so getting it right is essential.

If you could provide a few details about what you're looking to do, I would be happy to help. Some dimensions of the existing island and the desired size of the extension, a basic sketch of the plan and a photo or two would be enough for us to get started on a more thought-out plan.

Let me know what you think.
