Best way to do 4x 22mm holes in masonry

[RFw3Duwrd7Yu]

I'm delivering water feeds (via Speedfit 22mm) for a newly installed unvented cylinder in a cellar under the front sitting room to a utility room in the back of the house also on the ground floor. This will involve four separate 22mm feeds (cold supply, hot return, and supply/return for radiators). The most sensible route for this is under floorboards as we have suspended timber floors over bare earth in the two front rooms, and then (as the house is built into a slight slope of hillside) an earth floor with quarry tiles. I need to drill through two separate masonry walls (somewhere between 5-9" thick) to get this route to the cellar, and am thinking it would probably be wise to run pipes through a sleeve, so we're looking at four 30mm holes in a row for just over 5 inches wide.

I'm wondering if there is a more efficient way to create the gap for the pipes aside from simply drilling four adjacent holes with a 30mm SDS+ bit? Should I just remove a brick? This is my first renovation, so not really sure what options are out there! Any advice most welcome -

Should I just remove a brick?

Sounds like a plan.

Pipe insulation as sleeve will be sufficient.

Knock out a brick or 3. Install pipes with lagging/sleeve and patch up.

Even with soft brick and a guide template using a diamond core bit it would be hard work and50/50 chance of brick not falling apart.
