Our House Extension Services
No two properties are the same, which is why we offer bespoke extension solutions designed around your requirements.
Single Storey Extensions
Single storey extensions are one of the most popular ways to increase living space while improving the layout of your home. They are ideal for creating larger kitchens, open plan family rooms, dining areas, utility rooms, garden rooms, and home offices.
Our team ensures the new extension complements the existing property, creating a seamless transition between old and new.
Double Storey Extensions
A double storey extension is an excellent option for homeowners who need substantial additional space while making the most of their property’s footprint.
These projects can provide:
- Additional bedrooms
- Master suites with en suites
- Extra bathrooms
- Larger living areas
- Multi purpose family spaces
We carefully plan and construct every project to ensure structural integrity, energy efficiency, and compliance with current building regulations.
Kitchen Extensions
Many homeowners choose kitchen extensions to create bright and spacious living areas that become the heart of the home.
Benefits of a kitchen extension include:
- Increased natural light
- Improved functionality
- More storage space
- Open plan layouts
- Enhanced property value
Many modern kitchen extensions also incorporate durable flat roofing systems, making them an excellent choice for contemporary designs and open plan living spaces.
Garage Conversions
Converting an existing garage can provide valuable additional space without extending the footprint of your property.
Garage conversions are commonly used for:
- Home offices
- Guest bedrooms
- Children’s playrooms
- Home gyms
- Entertainment spaces
Our Extension Process
We believe that clear communication and careful planning are key to delivering a successful extension project.
Initial Consultation
We discuss your ideas, assess the property, and understand how you would like to use the additional space.
Planning and Design
Where required, we can work alongside architects and engineers to ensure the project meets planning requirements and building regulations.
Construction
Our experienced team carries out all structural works, roofing, and finishing works using quality materials and proven construction methods. If alterations to an existing roof structure are required, we can also undertake specialist roof repair works as part of the project.
Final Inspection and Completion
Before handover, we carry out a final inspection to ensure every aspect of the project meets our high standards and your expectations.
Why Extend Your Home?
Many homeowners throughout Cork and Kerry choose to extend rather than move house.
A professionally built extension can offer several benefits, including:
- Additional living space for a growing family
- Improved functionality and comfort
- Increased property value
- Avoiding the cost and disruption of moving
- Creating a home tailored to your lifestyle
- Maximising the potential of your existing property
For many families, extending a home is often more cost effective than purchasing a larger property once moving costs, legal fees, and stamp duty are considered.
