About us
A team of joiners, carpenters, electricians and building specialists — designing and hand-building premium garden rooms from our Sutton Coldfield base.
Four Oaks Garden Rooms was started by Tom Castledine as a passion project to deliver excellent quality garden rooms to customers in the local Sutton Coldfield area.
Tom is a time-served joiner/carpenter who founded Four Oaks to help people get quality garden rooms designed and built as premium products — completely unique to them.
Who We Are
Today we’re a fantastic group of experienced joiners, carpenters, electricians and building specialists who work together to help as many people as possible get the absolute best sustainable garden rooms — for longevity and quality of life.
Every member of the Four Oaks team has spent years perfecting their craft across many different projects, giving us the ability to tackle bespoke and intricate builds with passion, understanding and real quality control.
One of our biggest passions is to build everything from the ground up ourselves — no flatpack, no generic sizing, no prefabs. Every detail, done to an exacting standard, every time.
Our Ethos
Take your wildest ideas and turn them into premium, tangible structures — exactly the way you want them.
Ignite imagination and deliver rooms that live on through the quality and longevity of our craftsmanship.
Years of training, organisation and visualisation applied to every project, every time.
Our Approach
One of the things customers love about Four Oaks is that every new garden room is completely tailored to you — rather than a generic modular structure that would mean compromising on your vision.
You decide on everything from shape and style, right through to texture, finish and look — and we love bringing those visions to life. If the level of decision-making feels daunting, we’ll walk you through the options, but nothing is off the table.
Where it helps, we can keep costs down by working to standardised material sizes to avoid unnecessary waste — but this will never impede us from achieving your overall vision.
After all, you’re the one who will be using the space. It makes sense that you get free reign to design it around your needs.



“At Four Oaks Garden Rooms we understand that each of our clients require a unique style and purpose for their chosen garden room. We listen to the specification, consult carefully, then provide thorough visual design to allow a clear concept of each project. We work tirelessly to achieve the end vision — refined with excellent communication, militant planning and years of experience.”
From first sketch to final handover — every Four Oaks build is delivered by these faces.
