About

From 25 years, OSN Development Ltd have partnered with homeowners, designers and architects to deliver unrivalled construction, renovation and refurbishment services across London and the Home Counties.

Offering full project management, our passionate and hugely talented team are recognised for their expertise, professionalism and attention to detail.

From luxurious bathrooms to sympathetic renovation, choosing OSN Development Ltd guarantees an impressive end product that will satisfy for years to come.

Following an onsite visit to assess what you require, we will take care of everything, with design, planning, building control and construction all carried out to the highest industry standards.

During our initial visit, we may be able to supply you an on-the-spot quote, there and then. However, even if we have to prepare the quotation after our first visit, we’ll soon be in touch.

After talking you through every step of the process, and explaining if and why the local council needs to be notified, we will take care of all building regulations involved. Next, we’ll agree a time and date to begin work, after which you’ll see your vision being built before your very eyes. Our five-star, bespoke building service is ideal for residential and commercial properties alike.
