MNM Builders: Spring Has Arrived; The Perfect Time to Plan Your Home Extension

Mike McMann • March 26, 2026

Something about those first days of spring gets people thinking about their homes differently. The combination of the clocks going forward, the evenings getting lighter motivates homeowners to update their homes and to plan improvements and building work.

Is it time for a proper dining space that flows out into the garden?

If you have been considering the idea of a house extension for a while, March is one of the best times to start your project.

Here are some clear advantages to starting your project in the spring:

Why Spring Is Ideal for Extensions

Blueprints lie on a wooden table outdoors, overlooking a construction site with a concrete foundation and heavy equipment.

Building work is very much weather-dependent, especially in the early stages when groundwork and foundations are being laid. The worst of the winter frosts are behind us (fingers crossed!), the ground is workable again, and the longer days mean your builders can increase the number of hours for building requirements. Getting started in spring also means there is a great chance your extension will be finished and fully usable by summer; just in time to actually enjoy it.

What Could an Extension Do for You?

More Space Tailored to Your Life.


Whether you are dreaming of a larger open plan kitchen-diner, a dedicated home office, a playroom for your children, or a ground-floor bedroom for a family member, an extension gives you exactly the space you need, designed around how you actually live. No more squeezing around each other in a small kitchen or converting the dining table into a desk every Monday morning. Instead, space created can offer usable areas for all members of your family.

Adding Real Value to Your Home

At MNM Builders we know that a well-designed and properly built extension can add significant value to your property, often far more than the cost of the build itself. In many cases, homeowners see a return of anywhere between 10–20% added to the value of their property, sometimes more depending on the type of extension and location.


So it is not just about enjoying your home more now, it is a smart long-term investment too.


Avoiding the Hassle (and cost) of Moving. The current property market is no walk in the park. Estate agent fees, stamp duty, solicitors, the stress of viewings, chains falling through... it all adds up, and not just financially. For many homeowners, extending is simply the smarter, less painful option. You get the extra space you need without uprooting your life or leaving the neighbourhood you love.

Making Your Home Work Harder for You

One thing we hear a lot from our customers is that after an extension, their whole house just works better. Better flow between rooms, more natural light, a space that suits the way the family lives. It is amazing what a difference a thoughtfully planned extension can make to

your day-to-day quality of life.

What About Planning Permission?

Eyeglasses rest on a blueprint on a counter in a blurred, sunlit kitchen.

A lot of people worry about this, but many single-storey rear extensions actually fall under Permitted Development meaning you may not need full planning permission at all. Every property is different, though, so it is always worth checking. When you get in touch with us, we can help walk you through what is likely to apply to your home.

If you have decided that this spring is the time to build that extension you’ve always dreamed of, MNM Builders would love to help you to make that happen. Whether you have got a fully formed plan or you are just considering the idea, we are here to guide you throughout.
