Founded by Architects and property professionals, LEAF offers an impartial retrofit service. We aren’t affiliated with installers or contactors. We can offer the role of Retrofit Assessor, Retrofit Coordinator and Retrofit Designer in compliance with PAS 2035:2019 or we can simply offer Advisory, Assessor or Coordinator services, depending on your requirements. 

From affordable guidance to set you on your retrofit journey to full retrofit detailing - LEAF is your helpful and informed retrofit partner. 


What sets us apart is that we are Architects so we know how to detail and design buildings, the knowledge is already there and because we are qualified professionals we are inherently in tune with the liabilities and risks involved in the building process as a whole.


Our staged process delivers outcomes that can be utilised as standalone upgrades or feed into the next stage on the retrofit journey, whether that be next year or over the next 30 years. 

LEAF Retrofit Approach

Improving the buildings fabric for the future

LEAF provides whole house improvement plans generated from a holistic building approach. We only work with experienced architects to tailor procedures and put recommendations through enhanced software and hardware analysis to ensure that retrofit is done right once, to reduce risk of future maintenance expenditure (we diplomatically call this unintended consequences).

The general consensus is, that when it comes to Retrofit, there is not one size that fits all. The LEAF process allows clients to consider cost options and weigh up potential outcomes. In this way both public & private sectors as well as homeowners can find a tailored solution which suits their specific needs.
