Costs

How Much Is A Garage Conversion

A garage conversion is a smart, cost effective way to add usable space and value to your St Albans home. Often much cheaper than moving or building an extension. Costs vary based on the existing structure and your plans, but as a guide, single garage conversions typically range from £8,000–£20,000, double garages from £15,000–£35,000, and partial conversions start from £7,000. To provide an accurate quote, Craig will visit your property to assess the space and discuss your vision.

Had my garden renovation nicely done. Staff are attentive, sincere, efficient and knowledgeable. Able to answer to all my doubts and give constructive advice when facing contingent issues. They also clean up the place at the end of the project, no follow up cleaning needed. One good builder with integrity, knowledge, expertise and efficiency. Will definitely call them up for my next project. Highly recommended.

Assigning Craig to manage our life long dream of creating a big kitchen/living room (90sqm) was one of the best decisions we ever made. We got in touch with Craig 1 year in advance of works commencing and from the get go Craig scheduled an initial meeting to discuss our plans. Leaving the meeting Craig gave us new ideas and put no pressure on signing and was happy to work around us. Having visited several existing projects and received great customer feedback, we knew Craig was the builder for us as the quality of work was just exemplary. Craig saved us 5K by urging us to allow him to project manage the build and true to his word, he was on onsite multiple times per day, making sure everything was perfect. Along the way, we did encounter some problems, due to the existing condition of the garden but Craig always had a plan to work around them and not change designs with little or no change in cost. Craigs team are highly skilled, clean and respectful. They always tidied and locked up at the end of each day which left us worry free. One great trait about Craig; he treats his jobs like his own home and if he’s not happy with it, the project does not move to the next stage. It is no wonder he is respected in St Albans as a 5star builder. We will 100% be onboarding Craig again to do our 2nd story and driveway in the future. A big thankyou to Craig and his excellent team.

Craig and his guys did some work in our garden for us and completely transformed it. We couldn’t be happier with the quality of work. The guys working for Craig were polite, punctual and respectful. I will be going back to Craig for our next house project.

In the last couple of years we have used CJ Smiths to build us a house from scratch and also to completely renovate and extend our current home. We have been absolutely delighted with the service we have received and have recommended CJ Smiths to many friends and family. Craig and all of his team are professional, friendly and trustworthy and my family have always been pleased to have them working in our home. They are extremely tidy and mindful when working in a home with children, so we’ve never had to worry about any sharp edges/power tools being left around for little people to find! We have also never had to worry about builder’s bad language around the kids as they are all family men and are a pleasure to have around. The jobs have always been finished to a high standard and Craig is completely transparent when it comes to timings, costs, payment schedules and any delays that might crop up due to unforeseen circumstances like weather etc. The team works quickly and efficiently and you will actually miss them when they’re gone!!! Especially Terry the chippie who is completely wonderful and will even make a fuss of your dog and let it out for you if you need him to! 100% recommend CJ Smiths to anyone!
