Large & Small Scale Conversions
At Sully Construction, we specialise in large and small-scale conversion projects throughout Limerick and surrounding counties. With decades of industry expertise, we deliver high-quality building conversions that transform existing spaces into functional, stylish, and energy-efficient environments. Our professional team handles every aspect of the process — from planning and structural work to finishing details — ensuring seamless project delivery that exceeds client expectations.
Whether you’re looking to convert an attic, renovate a garage, or transform a commercial unit, we approach each project with precision, dedication, and a commitment to excellence.
Large Scale Conversion Services
Our large-scale conversions are designed for clients undertaking substantial structural or commercial renovations. These projects often involve significant architectural and engineering considerations, and our skilled team ensures that all work complies with Irish Building Regulations while maintaining the highest construction standards.
Commercial Building Conversions
We provide complete commercial conversions for offices, warehouses, retail premises, and industrial spaces. Our services include structural redesign, insulation upgrades, modern interior refits, accessibility improvements, and fire safety compliance. We help business owners revitalise outdated or underused spaces into functional, attractive, and efficient work environments.
​Apartment and Multi-Unit Conversions
We carry out multi-unit conversions, transforming large residential or commercial properties into self-contained apartments or duplexes. Our expertise covers space optimisation, soundproofing, fire safety systems, and efficient plumbing and electrical layouts, ensuring compliance with all local planning and housing standards.
Barn and Outbuilding Conversions
Many clients in rural Limerick choose to repurpose barns or agricultural buildings into modern homes or commercial units. Sully Construction manages the full conversion process — from reinforcing structural integrity to installing energy-efficient systems and bespoke interior finishes. These conversions combine traditional architecture with modern living, preserving the building’s heritage while enhancing comfort and usability.
Educational and Institutional Conversions
From schools to healthcare facilities, we convert institutional properties into modern, adaptable spaces that meet evolving needs. Our team works closely with architects, engineers, and stakeholders to deliver safe, accessible, and sustainable environments suitable for both public and private use.

Small Scale Conversion Services
For homeowners seeking to maximise their living space, Sully Construction offers a variety of small-scale conversion options that improve comfort and add value to their property. Each project is handled with the same level of professionalism and attention to detail as our larger builds.
Basement Conversions
Our basement conversions maximise the potential of underutilised spaces. We manage waterproofing, ventilation, drainage, and lighting to create habitable areas ideal for entertainment rooms, wine cellars, or additional bedrooms. With Sully Construction, you gain durable and stylish results that enhance both functionality and comfort.
Kitchen and Living Space Conversions
We also carry out open-plan living conversions, removing structural walls and redesigning layouts to create spacious, modern interiors. Our specialists ensure the right balance between aesthetics and structure, integrating steel beam installations and supportive frameworks where necessary.
Attic Conversions
An attic conversion is one of the most efficient ways to expand a home without extending its footprint. We design and construct bespoke attic spaces suitable for bedrooms, home offices, playrooms, or studios. Our process includes structural reinforcement, insulation installation, skylight fitting, and bespoke carpentry, ensuring a bright, comfortable, and compliant addition to your home.
Garage Conversions
We transform unused garages into functional living areas, such as home offices, gyms, or guest rooms. Each project is tailored to the homeowner’s needs, with full electrical wiring, insulation, heating, flooring, and interior finishes included. A well-planned garage conversion provides excellent return on investment and increases property value.
