5m x 3m Extension in Cheltenham

Project Overview

For this project in Cheltenham the client approached us wanting a supremely modern and luxury single storey extension that could seamlessly extend their living / dining space with maximum glazing and natural light.

Through a very extensive design process with our architects they opted for the best in class ALUK aluminium bifolding doors that completely opened up the extension to their exotically themed garden.

We carried out significant demolition & remedial, structural opening + external landscaping works to ensure the external and internal threshold levels remained flush throughout.

Given the clients clay soil and close proximity to trees the project involved traditional strip foundations to a depth of c. 2m and was delivered from start to finish within 4 weeks.

Our bespoke modular single storey extensions can be manufactured to almost any shape, appearance, configuration or size; and connect to any building type or age.

Our structural steel frame extensions are precision designed, engineered and installed by our expert team to provide optimum structural performance and thermal efficiency in line with all current building regulations.

Our systems offer an enhanced overall performance compared with traditional built extensions and aesthetically can be architecturally designed to be an exact match to the existing dwelling or stand out as a statement build.

Installation on-site is quick, clean and efficient due to our precision off-site manufacturing solutions that allow us to assemble your modular Extension with minimal noise, mess and disruption.

No cranes or heavy lifting equipment are required to complete the installations. Every component of your building has been carefully designed, enabling us to install in any location with even the most limited access.
