Our Process

Project brief
It all starts with a meeting at your property. We’ll discuss the project and your options and issue a budget cost for construction.

Design and structural
If you require planning drawings, our in-house architect can deliver these. We're also happy to help you appoint other architects and professionals.

Build
With paperwork, designs and deadlines done, it’s onto the most exciting part – bringing your much-anticipated concept to life.
The most important aspect of building work? Trust.
The right materials – yes. An experienced team – of course. But in my decade-long experience in building and construction, I’ve learned that you simply can’t bring an exciting vision for your home to life without complete trust in us, your building partner.
Over the years, our approach, attitude and experience has helped create some truly inspiring extensions, renovations and conversions. That’s why more than 80 per cent of our clients come to us through recommendation. I’m proud of that. And I’d love to talk to you about making your own dream project a reality.
Time to bring your project to life?
Trust our team of professional engineers and builders to make it happen.
Testimonials
Customer - TwickenhamBoiler, back windows, bathroom wares and radiators fitted, new wiring throughout, fitting only of new kitchen.I am very pleased to have chosen Rose Line Construction Ltd because the end result of the refurbishing of my house has exceed my expectations. For Michal Piasecki and his team no job was too small or too big and their professionalism and flexibility made easier an otherwise stressful time. They committed to a deadline for me to move in and worked very long hours to achieve this, particularly given the additional work that I agreed. Very good communication from start to finish. I would greatly recommend this company for its high standards of finishing at an accessible price.
