Ventilation ideas for small kitchen

[portlanders]

We have a Housing Association mid-terrace house, kitchen is 3.2m x 2.1m.

Our problem is we are forever having to wipe grease off the walls.

We have a humidity extractor fan on the ceiling near the exterior wall which extracts outside.
We've asked for a more powerful one, but the housing association have refused, and don't see there being a problem.
We also have a large kitchen hood, which doesn't seem that powerful, and only recirculates the air... it has a carbon filter.

I'm guess the solution would be to get a more powerful hood and have it extracting outside.
Thing is we only have the one external wall so the ducting will have to run along the side wall... not a problem, but there is hot and cold water pipes running in the corner of that external wall.

I would have to get someone in to do the ducting, make the hole in the exterior wall, and put a vent in.

Is the best solution, or is there other simpler options like replacing the humidity fan for a much more powerful one, if so any recommendations?

The existing fan is 100mm, with an extract rate of 90m3 per hour (25 ltrs/sec)
The cooker hood is 600mm wide, with an extract rate of 380m3 per hour.

All advice most welcome, I've attached a few photos.

Thank you

Will the housing association permit that?

If they will then that is probably the best solution. However, depending on how that fan in the middle of the ceiling extracts to the outside a better, (from a looks point of view), may be to extract through the ceiling and along to the wall. Depend if you have access to above the ceiling be removing upstaifs floorboards.

Good luck with it all.

Thanks,

I'll seek permission if that's the best solution.
To resolve a ventilation problem, for me to bear the cost i expect they'll give permission..... can only ask.

There is no access from the above floor, or rather i want to avoid that seeing i laid laminate flooring just 6 months ago.

The ceiling fan is extracted through a pipe above the ceiling to the external wall, can be no longer than 500mm.
