How we work with Landlords

We work with Landlords in a variety of ways to suit their particular circumstances. Whether funds for a major works refurbishment is required, or a wish to generate a significant capital sum, we understand the sensitivities of rooftop development and how to work with all stakeholders.

Minimal disturbance

First Penthouse was founded with the objective of minimising disturbance for existing occupiers. We understand that your property is your home and ensure that the majority of work is done off-site to make the development process as pleasant as possible.

Greener, Quicker, Smarter

Our award-winning projects are better for the environment, better quality and delivered in a quicker time frame than traditional construction. First Penthouse can produce the same product as a traditionally constructed penthouse in half the on-site time.
