1PT services ltd paid excellent attention to the project and joined with both the Owner and the Architect as a member of the development team. Their attitude was one of problem-solving, not problem-creation, and if the intention was there in the drawings, they assumed it was part of the contract. Some guys in the team has an architectural background and requested a few changes in the drawings which lead to great savings in the end.

It is a pleasure to leave a review after having an outstanding refurbishment service from team HWB. Many thanks for accepting the job at a very busy period of Christmas last year. Special thanks to estimations team and the administration at HWB to commence the project on time and deliver it before time.
As the property for us was an investment subject, which was offered to rent within 3 days of completion. The tenants and their family are extremely happy as well.
Looking forward to work together soon...!!

Exceptional Work and Service by Built-To-Last Construction
I am writing this review to express my utmost satisfaction and appreciation for the work done by Built-To-Last Construction on our new build and refurbishment project. From the quality of the work to the professionalism of the team, everything exceeded our expectations.
The workmanship was truly top-notch, with impeccable attention to detail. The finishes on both projects were beautifully done, truly reflecting the high level of skill and dedication that the team brings to their work.
Communication throughout the projects was exemplary. The team kept us informed every step of the way, ensuring we were kept up-to-date on progress and any changes. This transparency and constant open dialogue eliminated any potential stress and made the process seamless and enjoyable.
I would be remiss not to specifically mention Vasile, the director. His guidance, expertise, and hands-on approach were invaluable in ensuring our projects ran smoothly. He was consistently available for any questions or concerns we had and his leadership clearly sets the tone for the entire company. His passion for delivering quality results was evident in every interaction.
In conclusion, I wholeheartedly recommend Built-To-Last Construction to anyone looking for high-quality construction and renovation work. The name of their company perfectly encapsulates their work ethic and the results they deliver: truly built to last. Thank you, Built-To-Last Construction and Vasile, for making our vision come to life with such professionalism and integrity.

Gosch offers a high quality architectural design service. We design and draw projects of various scales from small extensions and loft conversions, basement extensions and complete remodelling works through to new build houses. Gosch will design your project and produce all the drawings and documents required for a permitted development or planning application. We'll make the submission to your local Council and will also give you friendly advice along the way.

We have completed two major projects with Gosch and the quality of design and finished result has helped us fully realise what we had hoped to achieve.
Simon’s superpower is to embrace all our ideas and then step them up, adding in real innovation, appreciation of the value of space and light, practical functionality and visual appeal.
There is no doubt we have ended up living in spaces with the ‘wow’ factor and benefitted from increased property value because subsequent buyers have also appreciated the design of the properties.
I recommend that anyone contact Gosch and get their ideas included in any project.

We specialise in internal refurbishment, renovation and fitouts projects for both residential and commercial properties. I have been in the trade for almost 15 years. Our team have a combined wealth of almost 50 years + of experience in the trade. We recently completed a 5 bedroom house in Ruislip, and coming to the end of our current project in Clayhall, 2 bedroom loft conversion.
Extensions can take many forms: from single or multi-storey extensions, to conservatories and sunrooms, each extension is different. Even if you’re extending a house that is identical to one you have worked on before, the customer’s criteria are probably not going to be the same. One customer may want French doors while another may want bi-folding, so the challenge is always new with each extension. However, the majority of property extensions involve flooring, bricklaying, door and window installation, electrical work, and decorating. For bathroom and kitchen extensions, plumbing is also a key factor.
Pretty much any part of your home can be extended. As such, you can include additional features to your extension that would benefit that particular space or room. You may want to include a skylight in your kitchen extension. Or, you may need to include advanced ventilation in a basement conversion. Perhaps you need extra insulation for a rear extension that receives little sunlight. Whatever extras you may need, be sure to discuss these with your builder before any building work begins.
I have a core construction team of eight builders and a wider network of trusted tradespeople, such as electricians, carpenters, and plumbers. I also regularly work with several architects and construction engineers who are able to assist in extension designs and building plans. In my three decades in the construction industry, I have been fortunate enough to build a great team of builders around me, as well as take on five apprentices. While we have the necessary industry qualifications, experience really is the most important thing in the construction industry. I’m proud to say that hundreds of professional extensions and satisfied customers can testify to our ability and craftsmanship.
