Expert Construction Services Across Worthing
From pre-construction to project completion, we'll work with you every step of the way.

Working across all of Sussex
House Extensions, Renovations & Everything in Between
Main Construction provides building services for homeowners across Worthing and Sussex, specialising in house extensions, renovations and property improvements. With over 42 years of experience, we have worked on a wide range of residential projects, helping homeowners create more practical, comfortable and better designed spaces.
Our extension work includes single-storey, two-storey, rear, and kitchen extensions. We work closely with you to understand how you use your property and create additional space that fits naturally with the existing building.
Alongside extensions, we also carry out full and partial renovations, including structural alterations, internal improvements and property upgrades.
Our experience across different areas of construction allows us to manage projects with a clear understanding of how each stage of the build connects, from the initial preparation through to the final finish.
Every project is approached with careful planning, quality workmanship and attention to detail. Based in Worthing, we work with homeowners throughout Sussex to deliver reliable building solutions that improve and add value to their properties.

Renovation
We carry out full and partial home renovations that typically involve structural alterations, layout changes, and upgrading ageing building services.
This includes work such as removing load-bearing walls with steel or RSJ installation, creating open-plan layouts, and reconfiguring room flow. We also handle first and second fix electrics, plumbing alterations, heating pipework changes, and full replastering following structural work.
Where required, we upgrade floors, insulation, windows, and doors to improve overall performance and compliance. Older properties often reveal issues once opened up, such as outdated wiring or previous structural changes that weren’t properly supported, which we resolve as part of the build.


Refurbishment
We deliver property refurbishments ranging from internal upgrades through to full strip-outs and reinstatement.
Works typically include kitchen and bathroom replacements, plumbing and electrical upgrades, plaster repairs, flooring installation, and full redecoration. For larger refurbishments, we carry out full internal reconfiguration including stud walls, insulation upgrades, plasterboarding, and full M&E updates.
We also address common issues in older properties such as damp, worn finishes, and outdated materials, ensuring the building is brought up to a modern standard rather than just cosmetically improved.
Interior design
Our interior design work focuses on practical layout planning, material selection, and coordination with construction works.
We develop room layouts, circulation flow, storage positioning, and lighting plans based on how the space will actually be used. We then specify finishes such as flooring, joinery, kitchen and bathroom layouts, and wall finishes, ensuring everything aligns with the build process.
Where we are also carrying out the construction, we coordinate design decisions with structural and services work so the finished space is consistent and buildable without on-site clashes.
