Turnkey service

At Ark Rooms we do things differently. We have designed a building service for a single storey extension, which puts client’s interests first. To provide total reassurance we deliver our unique One Stop Service, for a fixed price. Why can we do this when others can’t? Simple, because we are the designer, the manufacturer and the builder.

Our ‘turnkey’ service provides total peace of mind!  We manage every aspect of the building process, from design, planning permission and building control applications, to manufacturing and construction.


Bespoke Design

Your house is unique, why would your extension be anything less? Our Managing Director is an award winning architect and is Ark Rooms’ Design Director.

“We have a huge advantage over other architect practices and construction companies.  Our ‘design and build’ service removes the risk of a ‘loss in translation of quality’ between the architect and the builder, which can sometimes be a problem on conventional builds. With our ‘off-site’ manufacturing facilities in West Berkshire, we effectively control every aspect of the design and construction process – this has proved to be very reassuring for our clients.”

Annelies Rygole, Design Director

Construction Method

Ark Rooms has developed a unique system of construction which combines high performance insulation with the strength of a timber frame structure.  Our bespoke structural insulated panels (known as SIPS) are designed and constructed in our workshop, ensuring quality and consistency which is almost impossible to achieve with a conventional ‘on-site’ build. When all the components have been made, they are delivered to site and your extension is built in a matter of days, with a choice of finishes to accommodate and compliment the original house.

“Flexibility, quality and performance is designed into all of our extensions.  With thermal U-values exceeding conventional building techniques and a range of external finishes from traditional timber cladding to contemporary render and brick slip. Our extensions compliment and enhance all types of housing whilst delivering a highly insulated space.”

Peter Tompkins, Technical Director


Value for money

“Our fixed price estimate, that is easy to understand and free of industry jargon, is in line with our company values of integrity, innovation and excellence. We are able to offer our clients the reassurance of a fixed price, turn-key solution because we have all the necessary skills in-house. It enables Ark Rooms to deliver outstanding customer service and value for money.”

Our fully finished fixed price extensions start from as little as £14,750 excluding vat.
