Post by O'Halloran & O'Brien on LinkedIn: There are moments when you stop and realise an idea has become something much bigger than you imagined. Last Thursday's Leading Ladies Dinner was one of those moments. What started as a conversation between a group of women passionate about supporting one another has evolved into a growing community of leaders, allies and trailblazers from across infrastructure, construction and business. As one of the founders of Leading Ladies, it's incredibly rewarding to see so many talented women come together to share experiences, challenge each other, build meaningful connections and, most importantly, encourage one another to aim higher. Throughout the evening, there was one message that kept surfacing in different ways. None of us gets here alone. Whether it's a mentor who gives us confidence, a colleague who advocates for us, a friend who reminds us of our worth, or a leader who opens a door, behind every successful woman is often someone who saw something in her before she saw it herself. Our fantastic speakers, the Rt Hon Dame Penny Mordaunt and Cally Caroline Beaton shared stories that were insightful, thought-provoking and full of humour. Our wonderful host, Mims Davies MP for East Grinstead, Uckfield and villages, led conversations that challenged us to think about leadership, opportunity and the role we all play in helping others succeed. One particular discussion stayed with me. We talked about the people who encouraged us to take the next step in our careers, apply...

Post by O'Halloran & O'Brien on LinkedIn: We are delighted to have started work at Ransome’s Wharf—another exciting project for our long-standing client, London Square. We look forward to working alongside the wider project team to help deliver this landmark waterside development and 118 much-needed new homes for London. Ransome’s Wharf is underway! Last week we recorded our 8th start on site of 2026. Together these projects will deliver over 2,200 homes for London including for sale, affordable and build to rent properties. This waterside development, designed by 5PA Architects, will feature five blocks of low rise apartments set in landscaped gardens, with 118 homes, more than 19,000 sq ft of commercial space. Alongside other amenities, London Square will also invest in the renewal of Ransome’s Dock, enhancing the dock, waterfront environment and local public realm. This is the latest step in ensuring the delivery of new homes on a site which has been vacant for a decade. Since acquiring the stalled project in 2025, we have achieved an updated, compliant planning permission and partnered with Homes for Wandsworth on the affordable housing. And on Friday we began construction one day after achieving BSR Gateway 2 permission. Thanks to the project team and our partners who help us deliver at pace: Camlins Gravity Consulting Engineers Ltd O'Halloran & O'Brien Wandsworth Council Henry Castle-Smith Tom Hopkins Petar Valchev Ben Hawkins Vanessa Joyce
