Solid work, straight talk.
We plan, build and finish extensions, loft conversions, refurbishments and new builds — with one point of contact from quote to completion.
Building with trust, craftsmanship, and care
SilverO2 Construction Ltd is a small, dedicated building team delivering extensions, loft conversions, refurbishments, new builds, and specialist trade work — all coordinated by one point of contact from first quote to final handover. We keep crews small and jobs planned properly, so nothing gets rushed and nothing gets missed.

Extensions
More space, built to match the house you already have — not bolted on as an afterthought.
Single & double-storey extensions
Whether it's a rear kitchen extension, a side-return, or a full double-storey addition, we handle design coordination, structural work, and finishing under one roof — so you're not managing three different contractors.

- Groundworks, foundations & drainage
- Brick, block & timber frame construction
- Full internal finish, ready to decorate
Types of extension we build
Every property is different — here's a rough guide to the main options.
Single-storey rear extension
The most common way to extend a kitchen or living space out into the garden.
Double-storey extension
Adds space on both floors at once — often the most cost-effective way to add a bedroom.
Side-return extension
Builds into the unused side alley alongside a terraced or semi-detached house.
Wrap-around extension
Combines a side-return and rear extension into one continuous space.
Kitchen extension
A rear or side extension built specifically around an open-plan kitchen-diner.
Garden room / orangery
A lighter-touch addition for a home office, playroom, or extra reception space.
How it runs
The same four stages, every time, so you always know what's happening and when.
Survey & design
Site visit, measured survey, and drawings prepared or reviewed.
Fixed quote
A written, itemised quote with no surprise additions later.
Build
Groundworks through to structure, with regular progress updates.
Finish & handover
Snagging, sign-off, and a walkthrough before we leave site.
Loft Conversions
The space above your head, turned into a bedroom, office or bathroom that actually gets used.
Dormer, hip-to-gable & mansard
We assess your roof structure and headroom, then recommend the conversion type that gets you the most usable space for the least disruption — and manage building regulations and structural work throughout.
- Structural steels & floor strengthening
- Dormer or roof-line alterations
- Staircase design & installation
- Insulation, electrics & full finish
Types of loft conversion we build
The right option depends on your roof shape and how much headroom you have.
Dormer conversion
Extends the roof vertically at the back to create full head-height and floor space.
Hip-to-gable conversion
Straightens a sloped side roof into a vertical gable wall, adding significant space.
Mansard conversion
Replaces most of the roof slope for maximum space — often used on terraced houses.
Rooflight / Velux conversion
The simplest option where existing headroom already allows a usable room.
How it runs
The same four stages, every time, so you always know what's happening and when.
Survey & design
Roof survey, headroom check, and conversion type agreed.
