Architectural Services Home Extension Design
Single-storey, double storey, side and rear extensions designed around family life
Thoughtfully Designed Home Extensions
Whether you are considering a single-storey rear extension, double-storey extension, side extension or wrap-around extension, the right design can completely transform the way your home works for your family.
At Sasse Architectural Services, we specialise in designing bespoke home extensions that improve the flow, functionality and enjoyment of your home. We begin by understanding how you currently use your space and what is missing from your home today. From there, we develop intelligent design solutions that maximise the potential of your property while respecting your budget and long-term goals.
Many of our clients come to us wanting more space, but often the greatest improvements come from carefully rethinking the layout and how the different spaces connect together. Whether your goal is a larger kitchen, open-plan family living, a dedicated home office or additional accommodation, we help create homes that feel natural, balanced and effortless to live in.
Our service includes concept design, planning applications, technical drawings and coordination with structural engineers and Building Control, guiding you from the first ideas through to construction.
