At Quirks Property Maintenance Ltd, we regularly help homeowners across Wirral
Whether you are looking to create a home office, additional bedroom, utility room, gym, or open-plan living area, garage conversions are one of the most cost-effective ways to increase usable space and improve property value.

Popular garage conversion ideas include:
• Home offices
• Bedrooms
• Utility rooms
• Home gyms
• Playrooms
• Dining rooms
• Snug rooms
• Games rooms
• Hobby rooms
• Cinema rooms
Garage conversions are often significantly more affordable than traditional extensions because the main structure already exists.
What Types of Garage Conversions Do You Offer?
We provide a wide range of garage conversion services, including:
• Integral garage conversions
• Attached garage conversions
• Detached garage conversions
• Single garage conversions
• Double garage conversions
• Partial garage conversions

Every garage conversion is different, so we recommend arranging a quotation for accurate pricing.
Is a Garage Conversion Cheaper Than an Extension?
In most cases, yes.
Garage conversions are usually more cost-effective than traditional extensions because:
• Existing walls and roofs are already in place
• Foundations may already be suitable
• Less structural work is often required
• Build times are generally shorter
This can help reduce labour costs, structural costs, and overall project duration.
Can a Garage Conversion Add Value to My Home?
Yes. A professionally completed garage conversion can significantly increase property value.
Depending on the style of conversion and local property demand, a garage conversion may increase a property’s value by up to 10–20%.
Conversions that commonly add value include:
• Additional bedrooms
• Home offices
• Open-plan living areas
• Utility rooms
• En-suite accommodation
Do I Need Planning Permission for a Garage Conversion?
In many cases, planning permission is not required because garage conversions often fall under permitted development rights.
However, planning permission may still be required if:
• The garage is being extended
• The external appearance changes significantly
• The property is listed
• The property is in a conservation area
• Previous planning conditions restrict garage conversions
We can advise during the quotation process.

Yes. Garage conversions must comply with current Building Regulations.
This includes compliance relating to:
