Single-storey extension builder for Poole homes
A good single-storey extension is not just more floor area. We help you check the planning route, drawings, Building Control detail, foundations, drainage and build sequence before the work becomes expensive to change.

The person reviewing your photos, route and next step before the job turns into separate conversations with drawings, engineering, Building Control and builders.
Groundworks and foundation route
Planning your project
Tell us what you want to change at home. We will help work out the safe route.
You do not need to know the technical answer before you call. Start with the room, the problem and a few photos — we will explain whether you need drawings, calculations, approval or a builder first.
Recent work
Project photos from the stages that affect the plan.
Openings, steels, extensions, surveys and unfinished stages all change what drawings, approvals and builder pricing need to cover. Use the photos below to match your project to the closest route before you send the details.
Before you call
A few simple checks make the first conversation useful.
You do not need a full brief. These are the helpful details that let us point you in the right direction quickly.
Take a few photos of the room, the wall or extension area, and the outside access.
Tell us what you want the space to feel like, not just the technical work you think is needed.
Let us know if you already have drawings, calculations, planning approval or Building Control notes.
We will tell you the sensible next step before anyone talks you into unnecessary work.
Typical cost
Every extension needs measured drawings and a clear scope before a fixed build price is sensible. The first step is confirming size, access, drainage, structure and approval route.
Timing
Design and approval time depends on the route. The build normally moves through groundworks, shell, roof and windows, then handover or the agreed finishing scope.

How it works
Simple steps before the messy work starts.
01
Check the fit
We look at the size, access, drainage and planning route before you spend money on drawings or a build that may not suit the house.
02
Design and approve
Drawings, structural requirements and Building Control details are coordinated around how the extension will actually be built.
03
Build in order
The extension is planned in a clear sequence: groundworks, structure, roof, openings, then handover or agreed finishing work.
Questions
What homeowners ask before booking.
Do single-storey extensions in Poole need planning permission?
Some are Permitted Development, others need a householder application or Certificate of Lawfulness. We check this before the design route is fixed.
Can you price from a rough idea?
We can give route guidance, but a fixed build price needs measured information, drawings and scope boundaries.
Do you only do the shell?
The cleanest repeatable route is controlled shell and structural scope first. Finishing can be separately scoped when it is clear and approved.
Next step
Get a clear route before you commit to the build.
Send the room details, photos and postcode. We will tell you what needs checking before anyone prices or starts work.
