For homes with existing conservatories
Convert your conservatory into a fully Building Regulations–compliant extension
Using the innovative hup! system, Sussex Window Works can transform most conservatories into warm, beautiful living spaces — often while retaining your existing footings (around 95% of projects, subject to survey). Once compliant, the separating doors can be removed for a true open‑plan feel.
