Types Of Garage Conversions

Single-story attached garage conversion

A garage conversion on a single level is a truly advantageous and transformative process, meticulously executed to turn an underutilized garage space into valuable and functional living areas within a home. The beauty of this conversion lies in its seamless integration with the rest of the house, achieved by transforming an existing garage at the same level, saving you the trouble of dealing with additional stairs or elevations.

The possibilities with single-story attached garage conversions are both abundant and diverse, granting homeowners the freedom to create an extra bedroom, a productive home office, a delightful playroom for the kids, or even a personalized gym space for those fitness enthusiasts. What's more, this approach is impressively cost-effective, allowing homeowners to enhance their living environment without the need to bear the inconvenience and expenses that come with moving or embarking on major construction.

Repurposing the garage in this manner is truly a wise decision, enabling homeowners to maximize the potential of their property while adding practicality and substantial value to their home in a smooth and sophisticated manner.

Double-story attached garage conversion

A double-story attached garage conversion is an impressive project that involves transforming an underused two-story garage space into a valuable and practical living area. This conversion opens up the opportunity to utilize both the ground floor and upper level of the garage, providing a generous amount of space to explore various creative options. 

The extra space of a double-story garage conversion offers more options compared to the single-story alternative. Many St Albans homeowners have converted their area into additional bedrooms, a spacious home office, a versatile recreational space, or even a multifunctional living area tailored to their specific needs. 

The seamless integration of the converted garage with the rest of the house, ensures a harmonious and functional extension that enhances the overall appeal and value of the property. Opting for a double-storey attached garage conversion empowers you to unlock the true potential of your living space and elevate your lifestyle significantly.

Single-story detached garage conversion

Undertaking a single-storey detached garage conversion is another exciting project that involves transforming a separate and underutilized garage space into valuable living quarters within your property. This unique conversion allows homeowners to repurpose a detached garage, separate from the main house, into a versatile and functional living space. 

The possibilities are diverse, from creating the standard additional bedroom, a productive home office, a private studio, or even a serene retreat for relaxation. With meticulous planning and skilful execution, the detached garage seamlessly blends with the surrounding landscape, enhancing both the practicality and aesthetics of your property. Embracing a single-storey detached garage conversion empowers homeowners to optimize their space usage and craft an extraordinary and personalized living environment.

Double-story detached garage conversion

A double-storey detached garage conversion is an ambitious and exciting project that involves transforming a separate two-story garage structure into a valuable living space on the property. This conversion provides an excellent opportunity to repurpose a detached garage with multiple levels, resulting in functional and spacious living areas. 

Homeowners can explore various options, like turning the lower floor into a versatile home office or a delightful recreational lounge. At the same time, the upper level could become a cosy guest suite or an inspiring creative studio. 

With careful planning and skilled execution by C J Smiths, the converted garage seamlessly blends with the surroundings, adding practicality and enhanced curb appeal to the property. A double-storey detached garage conversion allows homeowners to create a truly unique and stylish living environment that perfectly complements their lifestyle.

How Much Does A Garage Conversions Cost?

The garage conversion cost in St Albans Hertfordshire can vary depending on several factors. The size of the garage and the extent of the space being converted will influence the overall expenses. More significant conversions may require more materials and labour, which can impact the final cost considerably. Additionally, the complexity of the project will play a role; more straightforward conversions with minimal structural changes might be more budget-friendly compared to more intricate ones.

In St Albans, custom designs and premium finishes are popular choices for garage conversions, but remember they can also influence the overall expense. The property’s location could also have an effect, as labor and material costs might differ slightly across the area.

Moreover, obtaining the necessary permits and ensuring compliance with local building regulations are crucial steps that may add to the total cost of the garage conversion. If homeowners plan to include additional features like unique plumbing fixtures, electrical work, or additional heating requirements, they should be prepared for the associated expenses.

To get an accurate estimate for a garage conversion in St Albans, it is advisable to consult a professional building company or contractor in the area. They can assess the unique aspects of the property, understand the specific requirements and preferences of the homeowners, and provide a detailed quote tailored to their needs and budget. C J Smiths would be delighted to be your building professional and offer you a detailed and accurate quote.

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.

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!

We have used Craig and his team for 3 home-renovation projects now, the last of which being July 2022 - we are looking forward to the team completing a 2-storey side extension for us later this year. - Trustworthy This is number one for us. They do what they say when they say they will do it and at the price agreed. Additional costs were extras added on / changed by us during the project. - Friendly Craig and his team have all been friendly and a pleasure to have in the property. They are polite and respectful and we are comfortable with them (especially as we have young children around). - Tidy The team tidy up at the end of each day and leave tools safely out the way. - Quality Work completed by Craig, his team & contractors has been to a high standard and where there has been a snag list, minor issues have been addressed promptly. -Communication Craig is available to us throughout each project by WhatsApp or phone. It helps having a central person to coordinate with all parties.

Highly recommended… We recently used CJ Smiths for an extension and full house renovation. From the first meeting, to completing the project, we found Craig and his team absolutely faultless. The project was on time but for unavoidable weather delays. There were also no surprises from a budget perspective. Anything that required an “extra” or a design change was met with a pragmatic response and always a mutually agreeable way of resolving - refreshing in a world where most things are viewed as a problem. Nothing was too much hassle for the CJ Smiths team, who always went above and beyond to ensure we were kept informed of every small change or decision that needed to be made. We even mildly miss the busy house when everyone was on site. A huge thank you to the entire CJ Smiths team - we are delighted with the end result and would highly recommend them to anyone embarking on a renovation.

Great service - very reliable friendly builders! We had our garden room built in St Albans by Cjsmiths, we found that the level of advice and service was a cut above the builders we have used in the past. During the planning phase, they answered all of our concerns and together we were able to plan and create the perfect space we wanted. The team were very polite and respectful during the build, cleaning up the site daily and treating our home and garden like it was their own! We are incredibly happy with the final result, it was completed on time and to a very high standard. We highly recommend Cjsmiths to anyone looking for builders in St Albans! Thanks

Outstanding job! Craig and his team completed an loft conversion for us at the beginning of this year and we couldn't be happier. We were so impressed by his level of professionalism from the very start. He managed our expectations and gave us a realistic timeline for the loft conversion to be completed, which ended up being very close to his estimate. We highly recommend C J Smiths for anyone looking for a loft conversion or building work in general. We will definitely be using C J Smiths again in the future. Great job!
