In this episode of Behind the Regs, Jack Calveley and Nader Hassan are joined by architect Níall Hedderman from Real Life Architecture for a practical conversation about home extensions, renovations, planning permission, Building Regulations, and the common mistakes homeowners make before a project even starts. Níall works closely with homeowners across the UK and has built a strong online presence through Real Life Architecture, helping people understand the building process in a clear and accessible way. In this episode, he shares his experience of guiding clients through the early stages of domestic projects and explains why the right professional advice at the right time can save homeowners significant stress, cost and delay. A major theme of the conversation is the difference between planning permission and Building Regulations. Many homeowners assume that once planning approval is granted, the project is ready to build. Níall explains why this is not the case, how the two systems operate separately, and why a design that achieves planning approval may still need to change to satisfy Building Regulations. The episode also explores permitted development, exemptions, garden rooms, loft conversions, home extensions, and the risks of relying on poor advice or online assumptions. Níall warns that “exempt” does not mean safe to ignore, and explains why homeowners should be careful about who they rely on when deciding whether Building Regulations apply. Jack, Nader and Níall also compare the systems in Scotland and England, including the different approaches to Building Control, approval before construction, building notices, private sector Registered Building Control Approvers, and the pressures currently affecting local authority services. Looking ahead, the conversation turns to future standards, including Passive House thinking, higher energy performance expectations, airtightness, insulation, and the increasing complexity facing architects, builders, homeowners and Building Control professionals. Topics covered include: • Planning permission vs Building Regulations• When homeowners should involve Building Control• Why early professional advice is so important• Common misconceptions around home extensions and exemptions• The risks of relying on informal or incorrect advice• Scotland vs England and how the systems differ• Building notices and the challenges they can create• Future energy standards and Passive House principles• Why the right architect, builder and project team make all the difference This episode is ideal for homeowners planning building work, architects, designers, builders, surveyors, Building Control professionals, and anyone who wants to better understand how domestic construction projects should be approached from the start. The key message is simple: good projects are rarely built on guesswork. They start with the right advice, at the right time, from the right people.
