Garage Conversions

For some home owners having a garage is not a necessity and is actually seen as a wasted space that could be utilised in other great ways. Over the years we have converted some really nice garages into living spaces that can be enjoyed by the whole family. Most recently we turned a north Cardiff garage into a lovely bespoke kitchen and cloakroom adding a raised roof and Velux windows for that extra bit of sunlight. Our garage conversion specialists in Cardiff are here to help.

Our builders in Cardiff found themselves as not just builders but people to turn to for advice. Here are our TOP 5 Do It Yourself tips for a successful DIY job.

ASK QUESTIONS – When you walk into a place like B&Q the shear amount of products on offer can be daunting to someone who is not from the construction trade. Why not settle these nerves and anxieties by asking a member of staff for advice. Our builders in Cardiff suggest seeking out help on the shop floor. TAKE PICTURES – This might sounds like a strange request but using your mobile phone to take snaps of what has broken in your house or what needs repairing can be a really good referencing point for the staff at any hardware store. This can reduce wasted journeys back and forth. DON’T START LATE IN THE DAY – We suggest you start as early as possible and we have learnt this lesson over the 30 years of trading. If something goes wrong and you need a part at 8pm on a Saturday this may prove tricky to say the least. Always set a timing schedule. CHOOSE SMALL TASKS – Do not and I repeat do not start your DIY project with a massive re floor of your living room, this is dangerous. Start with small tasks to learn from and make mistakes. Smaller successful tasks give you the confidence to tackle other larger tasks. BUY GOOD TOOLS – Do not be tempted by the cheaper alternative. If you invest in good tools they will last you for many years to come. Watch out though when other people use them


Finding a good builder can sometimes be a struggle, of course if you have found us then good job BUT we want to prepare you for finding a builder in Cardiff. It does not have to be a challenge, just follow these steps!

PREPARE A BRIEF Produce a written brief stating what you want done. Having a plan written on paper is much more beneficial for both parties involved. Remember this is your project thus you are in charge. Have copies to leave with a builder who quotes. GET QUOTES IN Receive quotes from 3 different companies. Our builders in Cardiff would recommend this to our clients just for re assurance. If you get a quote considerably cheaper than ours, ask yourself how they will achieve this without cutting corners? CHECK WHAT IS INCLUDED! Always make sure to understand what is included in the quote. Do not just sign away and pay without fully getting a breakdown of the schedule of work. TALK TO PREVIOUS CUSTOMERS Our builders in Cardiff on some occasions are asked for references of work. Always ask or ask to speak to a previous customer. A company like ours who are reputable would be more than happy to show you. Finding a good building company in Cardiff is not a hard task if you follow these proven steps to getting all the success you want from your building work. We wish you the best of luck.


Kitchens are the epicenter of any family home. With that in mind the long term success of your house as a resalable asset could be compromised by neglecting the style of your kitchen. Our kitchen fitters in Cardiff came up with some handy tips they have implemented to make a newly installed kitchen feel warm and worn in.   – Build a theme is what our kitchen fitters say. Pick objects or colours, things like vegetables or fruit along the lines of kitchen motifs   – Choose an area of your kitchen just for display purposes. Consider decorating an area of the cabinets or arrange your crockery in an appealing manner   – Show off your artwork, away from the sink of course. Even better, hang up your kids drawings around the kitchen, framed of course. What a lovely touch. Our kitchen fitters in Cardiff have seen this work and say it adds real value to the home.   – Use plants to add a sparkle of energy in the kitchen. Benefit from the neutral tones and create a warming and inviting environment for visitors and yourself.

What Can You Expect During Your Construction Work Being Carried Out?

For many people that require a construction task to be carried out, this means worrying about how exactly the job is going to pan out, from a design standpoint and a cost one. As a home-owner, we feel that it is vitally important to give you a general understanding of what to expect when a construction job is completed for you, weather it is commercial or domestic. Of course, nothing can ever go as perfectly as you would like it too, that is life! Within the construction trade, there is such a magnitude of variables that have the potential to go wrong but if you are aware that unexpected problems can arise, it will make you feel much better knowing that it is just part of the building process and issues can occur.

The Dewalt Angle Grinder that does not die...

A workman’s tools probably lead the hardest life in the construction industry.

Government now urging house-builders to apply for grants to build 'shared' ownership homes.

According to the figures, there is a total of £4.7bn in funding that is up for the taking from the government for house builders in the United Kingdom? Good news, right? There is a catch, the large sum of money that is up for the taking is to allow developers and house-builders to build over 150,000 shared ownership properties.
