Sandstone Engineering - Project 225 - Internal Remodelling

| Our Services

We specialize in residential developments for existing homes across London. Our expertise encompasses a range of projects, including extensions, loft conversions, and internal remodeling. With a focus on structural integrity and innovative design, we provide essential input throughout the development process.

Our involvement begins with thorough initial site visits, during which we assess the unique characteristics and requirements of your property. We then offer comprehensive structural design input during key stages of the project, particularly at Stages 3 and 4. This ensures that your vision is translated into practical, robust solutions that meet all regulatory requirements and construction standards.

Furthermore, we understand the importance of seamless collaboration between all parties involved in the project. To facilitate this, we arrange meetings with your contractor prior to the commencement of works. This allows us to align our structural design with the contractor’s plans, fostering a smooth transition from design to construction and ensuring the successful realization of your project.

The company was an absolute delight to collaborate with, and I wholeheartedly endorse them to anyone seeking this particular type of service. It was truly an exceptional experience, surpassing all my expectations. I unequivocally recommend Sandstone Engineering Ltd.

They promptly responded to all communication within 24 hours or in a few hour. I firmly believe that this company has the potential to be among the top 5 in the country.

A good trade review and the fact that Sandstone Engineering are local to us led us to engage them. We already had an architectural design for the remodelling of our ground floor and approached Safi and Naseem for the necessary structural drawings and calculations. The build involves extending the ground-floor accommodation at the rear of our house, taking down load-bearing internal and external walls, removing a chimney breast and designing the floor to accommodate underfloor heating throughout the ground floor. Having taken on board findings from trial pits and CCTV drain survey, Naseem and Safi have assembled a structural pack suitable for building regulation submission and for use by builders. They've been admirably responsive to questions from us, our architect and building contractors. Being very approachable and easy to work with, they have patiently explained relevant technical issues to us and have had several detailed meetings with our architect to find solutions that help with the build and reduce building costs. We wholeheartedly recommend Sandstone Engineering for their technical knowhow and for their friendly and personal service. They were fully committed to our project and supported and advised us not only on the structural aspects but also on matters that probably went beyond the scope of their work. This young and professional company deserves to do well. As construction approaches, we feel content that Sandstone Engineering will be as responsive as ever if we need further advice or if the builder encounters practical challenges.

I would highly recommend Sandstone Engineering and we can’t thank them enough because of their efficiency and technical knowledge. They were also super clear and supportive with all the queries around our roof extension. Added to that their fees were reasonable. You can tell they know their business, and importantly care for their work.
