We have really enjoyed working with Green Building Store on our selfbuild project. It was really helpful to be able to get the windows and doors and MVHR system from the same place. It also helps that Green Building Store really understands Passivhaus requirements and can offer good technical support for projects like ours.

Green Building Store are our trusted partners for windows and MVHR systems. When we’re working on a project they are the first people we contact, due to the combination of good quality products, knowledgeable technical support and great service.

The windows are lovely. I’m really pleased with them. It was really positive working with Green Building Store throughout the retrofit. Green Building Store’s aftersales team has also been great.

Working with Green Building Store has been fantastic. They have provided an excellent and professional service from our first contact, through design and delivery to the final installation. The windows are beautiful and of the highest quality and all the company’s representatives we have dealt with showed a high standard of professionalism.

The MVHR design process was very smooth, with the Green Building Store team working alongside the architects. The MVHR system is working very quietly and well.
Graham & Sally – Clients 2021
We will definitely do all we can to use your products on any future builds that we do. We have had zero problems with your doors and windows, in contrast to others that subcontractors have insisted that they use.
Andrew Hockley – Hockley Homes 2020
We have been really pleased with the quality of the ULTRA windows and doors from Green Building Store which have contributed to the overall energy performance of the project. Due to the success of this retrofit Passiframe now specifies Green Building Store windows and doors on all projects where possible.
Scott Adams – Passiframe 2020
I am already very familiar with Green Building Store’s windows and doors and know them to be good quality and robust..The clients are really happy with the windows and doors, including the big bi-fold doors, which really help bring the garden into the building.
Marianne Heaslip – Associate Principal URBED 2020
The ULTRA window range was the obvious choice for us. The U-values were in line with our needs and plans for Passivhaus certification. The support from Green Building Store was always first rate.
Rich Hibbert – Technical Manager PYC Group 2020
I’m always impressed with the quality of Green Building Store’s products, and the ULTRA windows and doors at Larch Corner are no exception. Without products of this outstanding calibre there is no way we would have achieved extraordinary standards of airtightness.
Mark Siddall – LEAP Architecture 2019
When it comes to MVHR systems for Passivhaus buildings, Green Building Store really understand the nuances and offer great support. I believe it’s their depth of understanding that makes working with them so incredibly effortless.
Mark Siddall- LEAP Architecture 2019
I have found everything to be spot on. The PERFORMANCE windows and doors are great. There have been no issues at all.
Pete Smith – Client 2019
We chose the PERFORMANCE range from Green Building Store because the clients wanted windows made from natural materials and the PERFORMANCE range offered good value for money for triple glazed windows. Green Building Store were very helpful with details and specification and were very thorough in putting together a comprehensive quote for the client and made ordering very efficient.
Sara Darwin – PHI Architects 2019
Thank you. We couldn’t be more impressed with the service we’ve had throughout from Green Building Store. You’ve been absolute professionals, really easy to deal with and all-round lovely folk!
Jo & Gail – Clients 2019
We specified the PERFORMANCE range because of its excellent value for performance and also because of the quality of Green Building Store’s customer service. We did some cost comparisons and these windows came out really well compared to competitors. Green Building Store is also very easy to work with and really supports us throughout the whole specification process.
Paul Testa – Architect 2019
During the whole of our major house refurbishment Green Building Store was the best company we dealt with, and indeed probably the best company we have ever dealt with in our life.
Alan & Monica – Clients 2018
We specify Green Building Store’s PERFORMANCE range of windows and doors regularly because they offer a good balance between cost and performance. They look great in our new office – we’re really thrilled with them.
Andrew Neal – Senior Architectural Technologist 2018
For me, achieving full Passivhaus certification on a retrofit project is the pinnacle of 20 years’ work and coincides with the length of my relationship with Green Building Store. Their products are often my first choice – not just because they offer excellent products but because their customer support – including the MVHR design service – and aftercare is second to none.
Gil Schalom – Architect 2018
Green Building Store’s AfterSales team were excellent …We really got the feeling that Green Building Store were on our side and batting for us. They have been a nice bunch of people to deal with.
Mark Watts – Architect & Developer 2018
I enjoy working with Green Building Store and Green Building Store windows and doors are our go to specification for high performance windows and doors. The combination of performance, cost and service is great, and difficult to find elsewhere.
Paul Testa – Architect 2018
We got a lot of technical advice and support from Green Building Store throughout our project. They are a really nice bunch of people and it has been a good experience to work with them.
Chris Copeman – Client 2018
Many thanks for the advice and care in designing the MVHR system. I’ve seen architects saying that Green Building Store are the most experienced suppliers in this field, but what they don’t say is how helpfully that expertise is provided.
