Exceptional location


With a prime City Centre location at the intersection of Leeson Street and Fitzwilliam Place, Hamilton House is a landmark building that instantly stands out from the surrounding rows of Georgian buildings.

In 1854, Hans Henry Hamilton took out a lease from the Pembroke Estate, for the site of 28 Fitzwilliam Place. The commission for the design of the very fine elegant Victorian Gothic Revival style house was given to the eminent Victorian architectural practice of Deane and Woodward. Initially the house, known as no. 26 Fitzwilliam Place, remained detached until the completion of the adjoining red bricked Georgian style terrace. When Hamilton died in 1875,
the property was sold to Christopher Palles, Chief Baron of the Exchequer, who was a devout Roman Catholic, and in 1878 he commissioned George Ashlin to design the chapel to the rear.

For over 160 years, 28 Fitzwilliam Place has remained a landmark building of distinction and we have taken great efforts to ensure it remains a modern day office location of excellence in the heart of Dublin 2.


What our clients say about
Hamilton House

We have been based in Hamilton House since we commenced our European business almost two years ago. The team, led by Claire have been outstanding and have been exceptional in catering for all our needs and requirements as we grew from a team of 2 to the current 8 people we have employed. The rapid growth of the team has brought the requirement for additional space and has posed several challenges for our business and Hamilton House always came up with a solution.

The facilities are of a very high standard and the level of service and support that we receive from the team at Hamilton House is exceptional.

Brian McNamara
MacKay Shields Europe Investment Management Limited

As a start up, we wanted our first office to be a reflection of the Company we were aspiring to be: professional, welcoming and managed by great people that take a genuine interest in what their Clients do as a business. The Team in HH could not have done more to achieve those qualities - they were a constant reassuring presence for us in our formative years.
