How To Plan A Home Extension Without The Stress
So, your house is feeling a little tight. Maybe you’ve run out of places to hide from your kids. Maybe your dining table is now doubling as an office, a school desk, and a storage unit. Whatever the reason, you’re thinking: “We need more space!” But the idea of builders stomping around, walls being knocked down, and the whole house turning into a construction site makes you want to curl up in a corner.
Don’t worry, we’ve got you covered. A home extension doesn’t have to be a nightmare. With the right plan, it can be as smooth as butter on warm toast. Let’s go step by step and make this process simple, stress-free, and maybe even a little exciting.
Step 1: Decide What You Actually Need
Before you start ringing up builders or getting lost in Pinterest boards, take a deep breath and ask yourself: What do I really need?
- Is it an extra bedroom because your kids have started fighting like wildcats over who gets the top bunk?
- A bigger kitchen so you’re not constantly elbowing someone while making a cup of tea?
- A home office because working from the sofa is making your back feel about 80 years older than it should?
Be clear on what you need, not just what looks nice in a magazine. Your new space should solve a problem, not just look pretty.
Step 2: Set a Budget (And Then Add a Little Extra)
Ah, money. The part nobody likes talking about but is very important. Extensions can cost anywhere from a few thousand to tens of thousands of pounds, depending on what you’re adding.
The trick here is: Set a budget and then add 10-20% extra for surprises. Because in the world of home improvements, surprises happen.
- You might find something unexpected in your walls (hopefully just bad wiring, not a hidden treasure that legally belongs to the government).
- Materials might cost more than expected.
- You might suddenly really want those fancy bi-fold doors.
Planning for these little extras means you won’t panic when they pop up.
Step 3: Get the Right Permissions (Yes, It’s a Thing)
Not every extension needs planning permission, but some do. And trust me, you don’t want to start building and then have the council knocking on your door telling you to stop.
- Smaller extensions (like single-storey rear extensions) often fall under Permitted Development, meaning you don’t need full permission.
- Bigger projects (or ones that change how your house looks from the street) might need planning approval.
- If you live in a listed building or a conservation area, even small changes might need permission.
Best thing to do? Check with your local council before you start. Or ask your builder, they should know.
Step 4: Find a Builder You Can Actually Trust
This is the biggest make-or-break part of the whole process. A good builder = a smooth, happy experience. A bad builder = stress, delays, and possibly a lot of shouting into a pillow.
How do you find a good one?
- Read reviews – If they’ve left customers happy before, that’s a great sign.
- Ask to see past projects – Any decent builder will be proud to show off their work.
- Get multiple quotes – If someone’s price is way lower than the others, be suspicious. Cheap work can become very expensive when things go wrong.
- Ask about timelines – A reliable builder will give you a clear idea of when things will start and finish (and actually stick to it).
At JP Hallam, we make this simple. No nonsense, no hidden costs, just good, honest building work.
Step 5: Make a Game Plan for the Mess
Okay, let’s be real. There will be mess. But you can prepare for it so it doesn’t take over your life.
- Set up a temporary kitchen or workspace if the extension affects key areas of your home.
- Store away valuables and breakables – dust has a way of sneaking into places you didn’t even know existed.
- Plan for noise – If you work from home, maybe invest in noise-cancelling headphones. Or, if possible, take a few days away when the loudest work is happening.
- If you have kids or pets, think about safety – Nobody wants a toddler or a Labrador running into a construction zone.
Good builders will keep the mess to a minimum and clean up after themselves (again, something we at JP Hallam take seriously!).
Step 6: Communicate, Communicate, Communicate
Builders are not mind readers. If you want something a certain way, say it early. Changes after work has started can be costly and slow everything down.
- Have a weekly check-in with your builder to see how things are going.
- If something looks off, speak up sooner rather than later.
- Get all agreements in writing, especially costs, timelines, and materials.
Step 7: Enjoy Your New Space! (And Brag About It a Little)
When all is said and done, you’ll have a brand-new space that makes life better. Your home will work for you, not against you. And when your friends come over and say, “Wow, this looks amazing!” you can smile, sip your tea, and say, “Yeah, I planned it all. No stress at all.”
(And if they ask for builder recommendations, well, you know where to send them 😉.)
