Garage Conversion/Garden Room Ideas
Popular Garage Conversion Ideas - Tailored to Your Home & Lifestyle
When it comes to garage conversions in Cambridgeshire, Fenland and Norfolk, the possibilities truly are endless. Every home is different, and every client has unique needs which is why we design each conversion around your lifestyle, budget and long-term goals. Whether you want to add living space, increase property value or create something totally bespoke, we can make it happen.
Here are some of the most popular garage conversion options we have completed for local homeowners:
1. Home Office Conversion
Create a quiet, private workspace where you can comfortably work from home. A garage home office is perfect for boosting productivity and separating work from family life.
2. Extra Bedroom or Guest Room
Transform unused space into a cosy and welcoming extra bedroom. Many clients choose to add an en-suite, creating a fully functional private suite for guests or family members.
3. Kitchen Extension / Open-Plan Living Area
Open up your home with a stunning kitchen extension. Converting your garage into part of a modern, open-plan living space can completely transform the heart of your home.
4. Home Gym Conversion
Enjoy the convenience of your own personal fitness area. We create strong, practical flooring solutions and layouts to suit all types of gym equipment.
5. Games Room or Entertainment Room
Turn your garage into a fun and exciting games room - perfect for kids, teenagers or adults who want a dedicated entertainment space to enjoy with friends and family.
6. Self-Contained Living Area / Annex
Ideal for extended family or rental use, we can build a fully self-contained living area with a kitchenette, bathroom, lounge and bedroom. A great way to add space and value to your property.
7. 3/4 Garage Conversions
You may not need to convert the entire garage. A partial conversion offers the best of both worlds - creating a playroom, office, utility room or hobby space while keeping valuable storage at one end.
Local Experts You Can Trust
As Property Services EXPERTS in Cambridgeshire, Fenland and Norfolk, we guide you from design to completion, ensuring your new space is functional, beautifully finished and built to last.
The conversion process typically involves removing the garage door and adding windows & doors, insulation, and interior finishes like plasterboard, flooring, and electrical fixtures. Once plastered and all carpentry work is completed we can then decorate and lay a number of different floor types if you wish for us to do so, this will be asked when we come over to your property for a FREE home visit.

Q. How much does it cost to convert my garage?
The cost of a garage conversion can vary depending on various factors such as the size of the garage, the level of finishes, the materials used, the client's requirements and the complexity of the project. To receive a tailor made quotation specifically designed to you and your requirements contact GCM Property Services.
Garage conversions are a cost effective way to add living space to your home compared to extensions and loft conversions. Garage conversions add additional space meaning you don't have to move and in the process adding value of up to 15% onto your home depending on the ceiling price in your area so it really is a win win.
What our lovely clients have to say
Very happy with my garage conversion into an office/gym. Matthew and Graham did a great job from start to finish. The project started on time and finished on time and the workmanship was top quality. Would definitely recommend.
- MM
Matt & Graham were so friendly and reliable, they made us feel comfortable - especially as a new Mum with a young baby at home. They talked through options we could consider on their first visit, so we had an idea of what could be achieved. They were flexible and open to us making tweaks of the plans throughout, to make sure we were happy with the end result. Thank you for your work and time, it was a real pleasure having you here!
- FF
Matthew and Graham did a fantastic job on my garage conversion. I found dealing with them very easy, and they were very communicative throughout the whole process. I really appreciate that when they sent over the initial quote, they detailed everything that would be done and what was covered. This really helped to ensure both sides knew what was in/out of scope. Any changes I needed, they were happy to accommodate. They arrived each day on time, and worked hard. Any issues that popped up, they sorted straight away with no fuss. Was a pleasure to have them, and I will be getting them back for more jobs!
