Our Services
New build homes start with the plot and end with a house you can move into. We handle site setup, drains, foundations, the shell and the fit out. Most plots around Caversham are single houses rather than estates. The new build homes page walks through the stages.
New home construction is the build stage itself, whether you already own the plot or are part way through with another contractor. We can pick a job up mid build as long as the existing work is sound. See the new home construction page for how that works.
Custom home design is where the layout gets shaped around how you actually live, before a brick is laid. Changing a plan on paper costs almost nothing. Changing it once the walls are up costs a great deal. More on the custom home design page.
Annexe construction gives you a self contained space for a relative or a lodger, either joined to the house or standing on its own. The planning rules are different from a normal extension. The annexe construction page explains what is usually allowed.
Barn conversions turn an agricultural building into a home. The frame, the roof and the openings all need checking before anything else is decided. Insulating an old structure without trapping damp is the tricky part. Read more on the barn conversions page.
Groundworks and foundations are the part nobody sees and everything else depends on. Soil type, trees nearby and drainage runs all change what the foundation needs to be. See the groundworks and foundations page for the options.

A straightforward detached house usually takes nine to twelve months on site once groundworks begin. Sloping plots, tricky access or deep foundations add to that. The design and planning stage before it can take just as long again, so build that into your timings.
Yes, and most of our new build work starts that way. We will read the drawings and the structural engineer's calculations first, then flag anything that will be awkward or costly to build before you commit. Some things draw beautifully and build badly.
Yes. Some clients want the whole thing handed over finished, others want us for the shell and want to do their own second fix. Both work. We agree in writing where our part stops so there is no argument later about who is doing what.
As a home builder, Stephen Anthony Developments has spent 34 years putting up houses and extensions around Reading. Building a whole house is a different job from working on an existing one, and it needs someone on site every day making decisions. That is how we have always run our new build work.
