Trying to create a utility

[JMC41]

Hi - I'm having my conservatory and kitchen renovated this year. Both separate rooms are going to become one big room with the kitchen at one side (where it is currently) and the conservatory becoming a living space. I want to create a utility space, with toilet, as there is already a toilet at the end of the kitchen so I thought why not make it bigger and put the washing machine in there with a sink and tall cupboard for hoover, mops etc. It has to go at the end of the kitchen, facing the garden as it will block the dining room if it is at the other end. I don't want it to compromise the new expanse of glazing that I am planning so wanted to keep it small with a pocket door (opposite the washer so that bending to get clothes out etc will be ok). I've looked at a few pictures but can't seem to get my head around the space. How small is too small. I was thinking 1.2m by 2.4m?
Is this impractical? Anybody got anything similar?

Can you post a floorplan of what you're thinking about?

I live in a country where people don't put their washing machines in the kitchen - everyone has a separate laundry even if in a large cupboard. I've seen many laundries / utility rooms as you describe or smaller.

Suggest google small laundries + toilet to get some ideas.

I have divided a large downstairs shower room to give utility space. The utility space is about 1m by 2.2. The door is central on one of the long sides. The washer and dryer are stacked to one side of the door facing into the room (cupboard 😂) and to the other side of the door is a water tank with shelving above. I reckon if I lost the tank there would be room for a loo and I could place a narrow handwash basin directly opposite the door without compromising access.
Or perhaps one of those toilets with the handwash basin set into the top of the cistern, that would work.
(But I have 3 toilets elsewhere in the house so not necessary)

Have a search for lootility. I think it’s a good use of space.

This is the architect's drawing but it leaves a very small kitchen. The toilet space is quite large and has a separate door which we are thinking of removing. We are thinking of shortening the length of it all.

will do

that looks fine for the utility but the space between the edge of the kitchen peninsula and the wall of the loo looks narrow (blue arrow).

i'd make the loo smaller and square to have slightly more kitchen space and less of a bottleneck on the way into the kitchen.
