Creativity, technical skill, and a commitment to quality

We specialise in creating steel and aluminium doors and windows that bring architectural vision and technical performance together. By managing every stage of the process — consultation, design, production and installation — we ensure consistency, accountability and clarity from start to finish. Architects, designers and homeowners choose us for the same reason we take pride in our work: attention to detail and a commitment to quality in every project.

Our Story

Built on experience

Perla was founded in 2015 by Nick, Dan and Sebastian. Having worked within the building trade, we had seen first-hand how poor communication, missed deadlines and lack of technical support could undermine even the best projects. We wanted to create a company that set a higher standard: one that combined specialist knowledge with dependable service and straightforward communication. From the beginning, our aim has been to be a partner that clients can trust to deliver on every promise and treat each project with the care it deserves.

Our Company

Guided by excellence

Our Approach

Crafting innovation, delivering excellence

Successful projects come from clear communication and careful planning. From the first meeting, we take time to understand your design ambitions and technical requirements. We then manage every stage in-house—from drawings and compliance through to production and installation. This integrated approach means you have a single, accountable partner throughout the process, ensuring projects progress smoothly and to the highest standard.

Our Expertise

Comprehensive experience in design and construction

We bring together technical knowledge and design understanding. Our team is highly experienced in building regulations, including fire safety and energy performance standards, and we remain proactive in keeping pace with changing requirements. At the same time, we recognise the importance of architectural vision. Our role is to balance both, providing expert guidance that ensures your designs are achievable, compliant and built to last. 

Our Services

A full-service partner for seamless delivery

We provide a complete end-to-end service, giving our clients the confidence of one dedicated partner throughout their project. Our service covers consultation, design support, production and installation, all delivered by our own teams. By keeping control of each stage, we are able to guarantee quality, efficiency and clear communication. Regardless of scope or scale, our clients know that every detail will be managed with care and professionalism. 

Our Commitment

Leading with quality, guided by clarity

We hold ourselves accountable to the principles of clarity, reliability and quality. Our clients can expect open communication, accurate timelines and consistent results at every stage. We understand the pressures of construction projects and are committed to reducing lead times while making the process smoother, not more complicated. Ultimately, we believe our success is measured by the success of the projects we help bring to life.

Our People

All together better

We are a friendly and diverse group united by a commitment to customer service. By working collaboratively, we bring together technical expertise and practical experience to deliver projects efficiently and to the highest standard.
