Helix - Home Extension - Wellyn

Client Name:



Home Extension


External dimensions: 6m by 3.18m
Internal height: 2.15m(min)
Internal area: 11.9msq
SIP Storage area: 2.0msq


Our client wanted to utilise the area to the side of the house by extending out and converting the space into a highly functional utility area. As the images reflect, the building is wedge shaped to maximise use of available space and flooded with natural light thanks to the three sky lights and glazed doors. Being a property extension, Planning Consent was required, which we arranged on behalf of our client.

Our Solution

Bespoke design: In every detail this build was bespoke, giving our client the very best solution for the space available, as well as functional and aesthetic aspirations.

Exceptional insulation: Walls, floor and ceiling built with SIPs panels which, due their structure, provide high level of insulation, further enhanced by an external layer of brick slips and energy efficient double glazing.

Brick slip cladding: Specialist composite backer boards are fixed to the SIPs panels and onto these the brick slips adhered and the mortar joints filled.

Kitchenette: This stylish kitchenette provides stacks of storage space and work surface as well as a large stainless-steel sink and drainer.

Sky lights: Three 0.8 x 0.8m roof lights provide fabulous natural light throughout the day and give the room a sense of spaciousness and height. 

Frames: uPVC frames with high security 5-point locking.

Heating: Minimal energy input will be required to maintain this room at comfortable temperature. To achieve this a wall mounted convector heater with thermostat and timer.

Electrics: 10 internal dimmable LED down lights (brushed metal finish) and 5 double power sockets, installed by our electrician and Part P certificated.
