JJC is a family run carpentry and construction team based in Littlehampton. We do not just build: we create bespoke garden rooms, home gyms, swimming pools, swim spas, ice baths, saunas and hot tubs that give you more room to live, work, train and unwind, and we take care of all aspects of finish works ourselves.
5-star rated GoogleJJC is a carpentry and construction company. Timber framing, groundworks, formwork, brickwork, joinery and finish works are the trades we come from, and they are still most of what we do every day. We have chosen to point those skills at the Wellness and Fitness sector: garden rooms, home gyms, swimming pools, swim spas, ice baths, saunas and hot tubs, built into homes and gardens across West Sussex and Surrey.
Every job is bespoke, designed around your garden, your house and how you want to use the space, not picked from a catalogue. We build with sustainably sourced timber and eco-friendly materials, because a space made for your wellbeing should be gentle on the planet too.
You deal with the same small team from the first sketch to the final detail, and customers say the same things again and again: the work is explained every step of the way, the team turns up when they say they will, the site is left spotless, and there are no hidden fees.
Your outdoor space can be more than a backdrop. It can be a sanctuary for health, relaxation and connection: a home gym you use every morning, a swim spa for training and recovery, a sauna and ice bath for the end of the day. Each one is a construction job before it is a luxury. It needs a properly formed base, a structure that will take the weight and the weather, and then the decking, cladding, steps and screening that make it look like it was always meant to be there.
Because we are carpenters and builders first, we do all of it ourselves, designed for your space, with one team and one point of contact.
And all aspects of finish works: decking, cladding, flooring, doors, lighting and the details that make the space feel finished.
Excellent workmanship and attention to detail. Jamie went the extra mile to get our Garden Room done on time.
Trusted names for swim spas, wellness equipment, composite decking and building materials.
Six clear services, all bespoke to your property. Most projects use more than one, which is exactly why we keep them all in house: one team from the first sketch to the final detail.
01 · SpecialismGarden rooms, home gyms, swimming pools, swim spas, ice baths, saunas and hot tubs, with the base, structure, decking and finish works all handled by us. Each space is designed around how you will use it, whether that is training, recovery or time with family.
02Fully insulated garden rooms and offices with 100mm insulation and FSC-certified double-glazed timber windows and doors, plus everything else built in timber. Timeless design and eco-friendly materials, for a space to work, train or unwind that is gentle on the planet.
03Whole-garden redesigns and the individual jobs that make up one: decking, sleeper terraces, patios, driveways, lawns, fencing and gates. A calm retreat, a space for entertaining or somewhere for the children to play, designed around your style and built with materials that last.
04The part most people never see, done properly. Formwork shapes concrete into foundations, slabs, walls and columns, and it is where the company's roots are: fifteen years of formwork on bridges and tunnels before JJC. Getting this right is what gives a pool, spa or garden room its strength for decades.
05Inside and out. Doors fitted into awkward old frames, staircases put right, fitted wardrobes, media walls, cladding and shop fit-outs. Sustainably sourced timber, precise work and a finish you will be proud of.
06Extensions, garage conversions, garage roofs and general building work, with the carpentry, groundworks and finishing all under one roof. Projects that add lasting value to your home and give you more room to live, work and enjoy.

“Jamie takes great care in his work, and explains his approach every step of the way. He thinks outside the box for clever and creative solutions when unexpected challenges arise during the build, and is also open to new ideas. The work started and was completed on time. Jamie is good at communication, easy to contact, and he always responds promptly. We are delighted with our new decking!”
“We recently moved and had a dangerous staircase where every step was a different height. We had been told that taking out the whole staircase and starting again was the only option. Jamie inspired us with confidence in his ability to find a solution from our very first contact with him. He worked literally step by step with meticulous measurements to even out the stairs without a total rebuild and with minimal disruption. He talked us through the whole process as he went along and carried out the work professionally and to a very high standard. A great job!”
