Types of Office Projects We Deliver
Mitchell McDermott has a high level of expertise in delivering a wide range of office construction projects, from constructing new build offices to upgrading existing stock. Below are the key types of office projects we deliver.

New Build Office Construction
We deliver the construction of new office spaces, ensuring that all aspects of the office design, planning and execution align with client needs, regulatory requirements and industry standards.
Flexible floorplate designs are essential for future-proofing new office building developments. Key aspects include modular layouts, column-free spaces, demountable partitions, flexible fire strategies, high quality amenity spaces, commuter centres, and mechanical and electrical adaptability. This approach ensures that office spaces can accommodate changing business needs and evolving workforce requirements.
Commercial Fit-Outs (Cat A and Cat B)
Fit-out projects are typically categorised into Cat A and Cat B based on the level of completion and tenant customisation required.
-
Cat A Fit-Out: This involves preparing a site’s core infrastructure—such as ceilings, lighting, air conditioning and raised access floors—so that it is ready for tenants to add their finishing touches.
-
Cat B Fit-Out: This goes a step further, providing more tailored finishes that suit specific tenant specifications, such as partitioning, flooring, audio-visual, canteens and kitchenettes, furniture and personalised design features. These projects transform a generic space into a customised office environment.
Existing Building Refurbishments
with ESG Improvements
Refurbishing existing office buildings not only enhances their aesthetics but adds significant value through ESG (Environmental, Social, and Governance) improvements. This includes the installation of insulating materials and other measures to improve energy efficiency, air tightness, reduced non-renewables and carbon use, more efficient building services, water use and biodiverse planting, contributing to long-term environmental and operational benefits.
Upgrades to Mechanical
& Electrical (M&E) Systems
Upgrading M&E systems is essential for improving the energy efficiency, the BER (Building Energy Rating), safety and functionality of office buildings. These upgrades include modernising heating, ventilation, air conditioning (HVAC) systems, electrical wiring and lighting to meet current standards and enhance occupant comfort and sustainability.
Office Accreditations
Following the establishment of the UN’s 2030 Agenda for Sustainable Development, sustainability has become a leading feature in modern building construction. Ireland has joined the EU’s mission to facilitate the construction of more Nearly Zero-Energy Buildings (NZEB).
Various accreditation schemes recognise sustainable practices. These include BREEAM, LEED, WELL, One Planet Living, and WiredScore. Tenants and investors increasingly prefer certified office spaces as they align with corporate ESG (Environmental, Social, and Governance) goals.
Façade Upgrades
Façade upgrades focus on enhancing a building’s exterior, improving both aesthetics and performance. This can involve thermal insulation, energy-efficient glazing or modern design elements that improve a building’s sustainability, air tightness and overall appeal.
Cycle Facilities
With an increasing focus on sustainable transport options, we manage the design and implementation of cycle facilities like bike racks, secure storage, showers and changing rooms. These upgrades encourage employees to use cycling as a healthier and more environmentally friendly commute option.
Fire Remediation Works
Fire safety is paramount in any property. Fire remediation works include upgrading fire safety systems such as sprinklers, fire alarms and means of escape, compartmentation, fire dampers, and insulation upgrades.
Landscaping Upgrades
Landscaping enhancements create a welcoming and sustainable environment for office occupants. This may include the introduction of green spaces, outdoor seating areas, external lighting, drainage, and sustainable and biodiverse plantings that contribute to both employee well-being and the building’s environmental credentials.
