Philip Behan Architectural Design and Planning
I specialise in designing contemporary and traditional homes, extensions, and retention plans — all crafted to meet your vision and secure planning permission with confidence.

New Home Design
I design modern and traditional homes tailored to your site, lifestyle, and vision. Every detail is considered—from natural light and site orientation to functionality and flow. My goal is to create a space that feels right from the start and fits beautifully into its surroundings.


Home Extensions & Renovations
Reimagine your existing space with carefully planned extensions that enhance how you live. Whether it’s more room for your family or better indoor-outdoor flow, I create designs that blend seamlessly with your existing home while meeting all planning regulations.
Planning Applications
I manage the entire planning permission process—so you don’t have to. From initial design to detailed planning drawings and application submission, we ensure every step meets the standards of your local authority and improves your chance of approval.


Retention Planning Application
If you’ve built or modified a structure without permission, we offer expert support in obtaining retention permission. We’ll assess your site, prepare the necessary documentation, and help bring your project into compliance with confidence and clarity.
EPA Percolation Testing & Trial Hole Excavation
As part of site suitability assessments for one-off rural houses, we offer EPA-compliant percolation testing and trial hole excavation. These are essential for evaluating soil conditions and ensuring proper wastewater treatment system design. My in-house service saves you time, coordinates smoothly with your planning process, and ensures full compliance with local authority requirements.


Site surveys
I carry out detailed site surveys to gather all the critical information needed before design work begins. This includes measuring site boundaries, assessing topography, identifying existing features, and evaluating access, drainage, and sunlight orientation. A precise site survey helps ensure that your design is accurate, planning-ready, and tailored to the unique conditions of your land.
