Details

Technical drawing service for a granny annexe SIP project. This digital drawing package is for customers who want a clearer annexe layout before moving into SIP kit pricing, panel scheduling or the next design stage.

It is designed for granny annexes, self-contained family accommodation, garden annexes and similar SIP shell projects where the layout, openings and overall footprint need to be set out clearly before a final SIP quote is confirmed.

What this drawing service is for

  • Turning your sketch, dimensions or brief into a clearer granny annexe layout.
  • Helping define wall runs, roof layout, window and door positions.
  • Creating a drawing basis that can be used for SIP kit pricing and follow-up discussion.
  • Checking the project shape before committing to a full SIP panel package.

What you get

  • Digital drawing pack to the agreed scope.
  • Small or large drawing option depending on project size and complexity.
  • Layout support for SIP wall and roof planning.
  • Opening positions shown from the information supplied.
  • Two free amendments for drawing work started from 03/04/2026.
  • Digital delivery to your account/email once ready.

Good information to send before we start

  • Overall external dimensions or a rough sketch.
  • Preferred room layout, including bedroom, bathroom, kitchen/living space if relevant.
  • Window and door sizes if you already have them.
  • Roof preference, such as flat roof, mono pitch or dual pitch.
  • Whether the annexe is intended as habitable accommodation.
  • Any planning, Building Control or site restrictions you already know about.

Important exclusions

This is a drawing service, not a full architectural appointment or engineering approval. Unless separately agreed, it does not include planning submission, Building Control approval, structural calculations, SAP/energy assessment, drainage design, foundation design, site survey, installation, windows, doors, cladding or the SIP kit itself.

If the annexe is intended as habitable accommodation, Building Control, planning and structural requirements may apply. We can help prepare the SIP layout and quote, but final compliance should be confirmed by the relevant professional or approval body.

Delivery and lead time

This product is supplied digitally. There is no physical delivery charge for the drawing package. Typical lead time is around 7-14 days, depending on the information supplied and the current drawing workload.

FAQs

Is this a full planning or Building Control package?

No. This is a digital technical drawing service for layout and SIP kit planning. Planning submissions, Building Control approval, structural calculations and energy assessments are not included unless separately agreed.

Can this be used for a habitable granny annexe?

It can be used as an early drawing and pricing step, but habitable annexes may need planning, Building Control, structural design and energy assessment input before construction.

What do I need to provide?

Send external dimensions, a sketch or brief, preferred room layout, window and door sizes if known, roof preference and any site restrictions you already know about.

Is the drawing supplied digitally?

Yes. The drawing package is supplied digitally to your account or email once ready, so there is no physical delivery charge.
