Rear Extension with incorporated W/C advice

[M_Wels]

Hi all,

 

We’re planning a single-storey kitchen extension at the rear of the house and want to incorporate the existing ground-floor W/C into the new layout.

 

We’re also considering removing the chimney breast in the lounge and putting up a stud wall instead to make that room slightly smaller but allow more usable space for the open-plan dining/kitchen area.

 

Option 1: Move the W/C to the front of the house within a new utility room. My concern is that relocating the soil pipe might make this the more expensive option. Sewage hole is under the current conservatory floor. 

 

Option 2: Keep the W/C roughly in the centre of the house but reconfigure it — make it slimmer and longer to free up more space for the kitchen/dining area.

 

Before we go too far down one route, I’d really appreciate any feedback or alternative layout ideas from people who’ve done similar extensions — especially if there’s a smarter or more cost-efficient way to handle the W/C location.

 

Thanks in advance!

All your plans show blocking direct access from the hall to the new kitchen.  I would not want to have to go round through the living room all the time to get to the kitchen.

 

If the "Sewage hole" (you probably mean inspection chamber) is in the conservatory then you probably have some drainage relocation and re routing to do before you can build a proper extension.

Given you need to move the WC to make the open plan work at all, then I'd definitely go for something like option 1 - in the scheme of things, moving the WC that bit further isn't going to make that much difference and may even be easier - it looks like you have side access (there's a side window) so fairly easy to connect to the existing drains. Option 2 really compromises the open plan feel. I agree with @ProDave that you'd benefit from a door between hall and kitchen.

+1 to a door between entrance & kitchen - in fact I'd probably make a full hallway:

Thank you, the drainage is something I’m now looking into further, much appreciated

Okay good to know, I was conscious that such a move for the WC might be a great add on to the budget. Seems to be the best solution

Thank you for creating this, I can understand how the dual access from hall and living room would work. There would also be natural light in both the utility and w/c which would be ideal.
