Restoration & Refurbishment- 22 Jul 2026
Hired for a kitchen refit and other works including removing a wall to open kitchen out. Understood the job, and where appropriate offered helpful suggestions. Excellent communication throughout, I was always aware of the current status of the job. Work performed exceeded expectations - and I hope they will be free next time I have works that need doing.
Poynts Works Ltd
Rating: 5 out of 5
Conversion Specialist in Thornton Heath
I'm an ARB Registered Architect with 18 years' experience designing residential extensions, renovations and conversions across London. I work directly with homeowners from the earliest ideas through planning permission, Building Regulations and, where required, construction on site. Every project begins by understanding how you want to live. Using sketches, 3D models and visualisations, we can explore different options together before you commit to building work, giving you confidence that the design is right for your home and your budget. Once the design is agreed, I prepare the detailed technical information needed for construction and remain closely involved throughout the build, helping resolve questions on site and ensuring the original design intent is delivered. If you're considering extending or renovating your home, I'd be happy to arrange a free initial conversation to discuss your ideas, the likely planning implications and the next steps.

Conversions - General- 13 Nov 2014
Dear Martin, I can't thank you enough for the fantastic job you did on the Garage conversion...and completing on schedule! You and your team were extremely professional and courteous. - Your rates were clear with no hidden extras - You always turned up promptly - even working late to meet our deadline! - You were patiently accommodating of any changes with the plans (no matter how many times we interrupted you with changes or questions) - You complied with building regs - You kept us up to date with progress and made helpful suggestions on things we hadn't thought of - You helped us to minimise cost and stick to budget - The quality of your work is excellent and I look forward to you and your lovely hardworking and professional team coming back to tackle the work we've re-booked you for (although I am going to have to compete with the neighbours, friends & family who are now wanting to book you!) We met with a handful of builders for the job, both myself and my husband had immediately decided upon you due to your straightforward, no 'humming and harring' and the confidence you inspired - it was the correct decision. Very Grateful indeed! Best Wishes Anna M - Beckenham

Restoration & Refurbishment- 17 Jul 2016
Valter was very impressive on his initial visit with some exciting ideas for the house improvements and we had no hesitation in choosing Happy Building above the other two building firms who quoted. Having signed off on the budget and scope of work, Valter's team of builders arrived. We were hugely impressed with the skill, experience and work ethic of the team; the fact that they arrived early each morning smiling underlined the "Happy Building" epithet; Jarek, the site foreman, had an especially cheery demeanour. The work involved stripping the walls back to bricks, removing walls, reinforcing foundations, plastering, extending the bathroom and removing one bedroom to create a large ensuite bedroom. The latter certainly would not have been done without Valter's vision and patience in explaining how it would look. We were able to deviate from the original plans without any problem which was very important in achieving the final look which we had desired. Valter was very careful in sticking to time and budgets which I had never experienced before with builders. The kitchen, bathroom, two bedrooms, living room and hallways were finished to the highest possible specification within our budget. There were one or two small features which, with hindsight, we would have improved such as door handles and shower fittings, however this was down to us not specifying exactly what we wanted. These are very minor details and a tiny part of the overall picture.

Restoration & Refurbishment- 20 Jul 2015
We hired Zebra Property for a complete strip out and refurbishment of a GF flat. The JOB: The job included initial removal of existing bathroom, kitchen and flooring. The works itself were for a side return wrap around kitchen extension, basement refit, installation of new kitchen and bathroom, new windows (including velux) and bifold doors, tiling and complete decoration throughout. FEEDBACK: Zebra were a great company to work with on this job. Communication levels were clear. There were inevitable delays to the project but there was always a focus to get back on track and deliver as quickly as possible. The resulting finish is a high standard throughout the property, with any minor snags completed quickly. Thank you!
