If you share a house, you already know the hardest part of working from home isn't the work. It's the doorbell at eleven, the housemate starting a call two feet from your desk, the washing machine hitting its spin cycle exactly as you're trying to sound competent on a video call. Shared houses and thin Victorian walls were never designed around conference calls. Most of it is fixable with a few cheap adjustments and one slightly awkward conversation, held once, rather than a daily drip of irritation.

Start with a week of noticing

Before you buy anything or negotiate anything, spend a few days writing down what actually breaks your focus. Not what you assume does, what does. Note the time, the trigger and roughly how long it took you to get back into the task.

Most people find the pattern is narrower than they expected. It's rarely "the whole house is noisy". It's usually three or four repeat offenders: the one o'clock kitchen rush, the front door slamming, the housemate who knocks "just quickly" while you're mid-sentence, and the evening bandwidth spike.

Once you can name the offenders, you can deal with them one at a time. A general plea for quiet gets you a shrug. "Can we keep calls off the landing between ten and twelve?" gets you a yes.

Deal with noise before you deal with people

Sound travels through gaps far more than through walls. Close the gaps first, because it's easier than asking anyone to change their habits.

• Seal the door. A draught excluder along the bottom and brush strips around the frame cut a surprising amount of corridor noise for very little money.
• Point your desk at a wall, not the doorway. Soft surfaces behind you absorb sound; hard ones bounce it straight back into your microphone.
• Get something soft into the room. A rug, a curtain, a bookcase with actual books, a beanbag in the corner. Empty rooms echo. Full ones don't.
• Use headphones with a boom mic. Even a modest wired set stops your calls leaking into the rest of the house, which makes everyone more relaxed about you being on them.
• Try low-volume brown noise. The aim isn't to drown the house out but to blur speech, so your brain stops trying to follow it. Other people's conversations are uniquely distracting because you can't help parsing the words.

If there's a spare room, a loft or even a landing desk you can claim, claim it. A dedicated spot does more for concentration than any gadget, because it tells both you and everyone else that work is happening there.

Make yourself visibly unavailable

Most interruptions aren't malicious. They're the result of you looking available. Sitting at the kitchen table with a laptop open reads as "free to chat", whatever the screen says.

So make your status legible from across the room:

• A cheap whiteboard or printed card on the door: "On a call until 11.30" on one side, "Free after 12" on the other.
• Headphones on means do not disturb. Agree that rule out loud so it carries weight.
• A predictable lunch window, so nobody has to guess when to catch you.
• The same desk, at the same times, most days. Routine does the explaining for you.

Then make interrupting you cheap to end. If someone knocks, don't wait for them to finish their story. Say: "I've got until half eleven, want to grab a coffee then?" You've acknowledged them, and you've deferred the chat to a time that suits you both.

Three scripts that keep the peace

Boundary conversations go wrong when they sound like complaints. Frame them as logistics: a problem you're solving together, not a character flaw they need to fix. Keep it short, keep it concrete, and offer something back.

1. The pre-emptive ask. "I've got client calls most mornings. Would it work if we kept the kitchen quiet-ish until twelve, and I'll stay out of your way after that?"
2. The specific request. "Could you take personal calls in your room rather than the landing? I can hear every word from my desk."
3. The renegotiation. "The six o'clock slot is getting sticky for me. Can we shift the big downloads to after nine?"

People agree to trades far more readily than to rules. Ask for a small change, name the window it applies to, and stick to your side of the bargain.

Shared Wi-Fi when everyone is online at once

Bandwidth is shared along the whole line, so the issue isn't only how many people are online. It's what they're doing. Game updates, cloud backups, huge downloads and 4K streams will flatten a call faster than four people browsing ever will.

• Plug in. If there's any way to run an Ethernet cable from the router to your desk, do it. It's dull, it's slightly ugly, and it works.
• Schedule the heavy stuff overnight. Consoles, phones and laptops all let you set a download window. Ask the household to use it.
• Move the router. Boxed in behind the television or sitting on the floor is the worst place for it. Central, high and out in the open is better.
• Keep a mobile hotspot as a fallback for calls only, so a bad evening doesn't cost you a meeting.
• Sort the admin. If the broadband contract is in your name, or you're about to sign a shared one, read the terms and put any agreement about splitting bills in writing. If it touches your tenancy, take proper advice.

None of this will rescue a genuinely underpowered connection, so be realistic about what a new router can and can't fix before you spend money on one.

The ten-minute Sunday reset

Once a week, sit down for ten minutes and review how it went. Which interruptions actually happened? Which ones have stopped? Is the door seal still doing its job, and is the house still sticking to the quiet window you agreed?

Then reset the small things: rewrite the door sign for the week ahead, check your calendar for the calls that matter most, and pick one housemate conversation worth having before Monday. Working from a shared house is mostly a matter of maintenance rather than willpower. Fix the recurring friction once, properly, and you get your attention back every single day.
