02 — Floor plans
Which drawings you need
An estate agent's floor plan is not accurate enough for building work. A planning application needs drawings that show the outside of the house and what will change. Building Regulations approval needs drawings that show how it will be built. A builder needs accurate drawings to give you a price.
We draw plans for homes across Poole, including Parkstone, Branksome, Lilliput, Canford Cliffs, Hamworthy and Broadstone.
What this covers
- Plans of your house as it is now, drawn from measurements we take.
- Plans of the changes you want.
- Drawings for a planning application, if you need one.
- Drawings for Building Regulations approval.
- A check on whether you need planning permission. Some extensions can be built without it under rules called permitted development.

Stage 3
We draw them
We measure the house and draw the plans. You can use them to apply for approval or to get the work priced.
Why homeowners choose us
The people who draw your project are the people who build it. So the drawings are made to be built, not just to get approval, and we price each item on them before you commit.

The price is agreed from the drawings
The build price only changes if you change the design.
One firm and one contract
You don't have to find and manage separate designers, engineers and builders.
You can stop after any step
The drawings are yours to use with any builder.
Can I do this to my house?
Answer three or four quick questions to see what your project is likely to need before you speak to anyone.
What your project is likely to need

How a building project works
Every extension, knock-through or loft conversion has four stages. We do all four.
- 01
Drawings
We measure your house and draw it as it is now. Then we draw the new layout.
- 02
Approvals
We apply for planning permission if you need it, and prepare the Building Regulations drawings. Building Control is an independent inspector. They check the work and sign it off.
- 03
Engineering
A structural engineer works out the size of any steel beams and foundations before building starts.
- 04
Building work
We do the building work and finish the rooms.
Floor plans are the first stage. Everything after them is based on the drawings.
What can go wrong, and how we stop it
What goes wrong
How we stop it
The price goes up once building starts.
We price the building work from our own finished drawings, so the price is agreed before work starts.
The steel beam is the wrong size, or rests on the wrong thing.
A structural engineer sizes the beam and what it rests on before building starts. Building Control checks it on site.
Old chimney breasts, pipes or cables turn up once the wall comes out.
We look at what the wall holds up and what runs through it before the drawings are finished.
A neighbour dispute holds the job up.
We tell you early if the Party Wall Act applies, so notices go out before the work is planned.
You find out too late that you needed planning permission.
We tell you at the free review whether you need planning permission, and we make the application if you do.

Step 3
Cost estimate
Once you have a layout you like, we estimate what it would cost to build.

Drawings, approvals and engineering
Full drawings, structural calculations, and the planning and Building Regulations applications. The house is measured at this stage if it hasn't been already.
Priced after the estimate
Step 5
The build

“…they can do everything from start to finish for you.”
“…carried out layout drawings for a very reasonable amount. Josh also gave us a budget price to carry out the works.”
“I couldn't recommend Josh enough! He has been absolutely fantastic, nothing was too much trouble, he was happy to bounce lots of ideas back and forth until we were happy. He is polite, friendly and professional in every aspect. I would definitely be using his services again in the future when needed.”
“Josh got the plans for our extension completed and submitted very quickly. We had a number of amendments and obstacles to overcome but nothing was too much trouble for him. A very professional and efficient service.”

Questions about Floor Plans in Poole
What floor plans do I need for a Poole extension?
It depends on what the drawings are for. Planning drawings show the council what you want to build. Building Control drawings show how the build will meet the building regulations. Builder quote packs give builders enough detail to price the job.
Can I use estate agent floor plans for builders?
Usually not on their own. Estate agent plans can help explain the layout, but builders and engineers normally need accurate dimensions, notes on what is changing and technical details before they can price the job properly.
Do floor plans need a measured survey?
If the project depends on accurate existing dimensions, yes. Photos and estate agent plans can start the conversation, but a measured survey means the drawings are based on accurate measurements.
Can PlanBuild help after the plans?
Yes. We can continue into planning drawings, structural calculations, Building Control, builder quote packs and the build.

Tell us what you want to change
Send a few details and we will call you back the same working day to tell you what your project needs. There is no cost and no obligation.
