Affluent homeowners in North Berwick often approach home extensions with a desire for more than additional square footage, they want spaces that elevate daily living. At McMillan Developments, luxury design begins with architectural cohesion. Extensions should feel seamless, not “added on,” which means matching proportions, rooflines and sightlines so the new space enhances the home’s overall character.
Premium materials also play a central role. High‑end glazing, natural stone, bespoke joinery and energy‑efficient systems create a refined finish while improving long‑term value. For coastal properties, we consider durability against salt air and weather exposure, ensuring your investment performs beautifully for decades.
Lighting design is another hallmark of luxury. Large-format windows, skylights and strategically placed LEDs help create bright, modern interiors that feel expansive and inviting. Whether you’re envisioning a contemporary kitchen extension or a serene garden‑facing lounge, thoughtful lighting transforms how the space is experienced. Finally, affluent clients often prioritise lifestyle‑driven layouts, open‑plan entertaining areas, spa‑inspired bathrooms, or multifunctional family zones. Our design team works closely with you to ensure your house extensions support the way you live now and in the future.
PLANNING PERMISSIONS & BUILDING WARRANT GUIDANCE
Navigating permissions in North Berwick can feel overwhelming, especially for larger or architecturally ambitious projects. McMillan Developments provides full guidance from the outset, helping you understand when planning permission is required, what documents must be submitted and how local regulations may influence design.
We also manage building warrant applications, ensuring structural plans, engineering details and safety standards meet all statutory requirements. This proactive approach prevents delays and keeps your project moving smoothly. For heritage or conservation‑area homes, we offer tailored advice to help maintain architectural integrity while achieving modern functionality.
