The process

How it works

01

Free consultation

We visit your home to discuss your ideas, give suggestions and explain the process. We then prepare a written quotation inclusive of all fees. Free for homeowners — prospective purchasers and developers are charged £50/hr + travel.

02

Measured survey

Once you accept the quotation, we arrange a survey at a mutually convenient time. This takes one to three hours depending on the project. We then produce your existing drawings and issue an invoice — paid before we proceed.

03

Design drawings

Working with you, we produce sketch designs and proposal drawings for your approval. Up to three sets of revisions are included — any additional revisions or work beyond the agreed scope is charged at £50/hr.

04

Planning submission

We complete all required forms and submit your planning application to Leeds City Council or Bradford Council. We liaise with planners throughout and keep you informed. Decisions typically take up to eight weeks.

05

Construction drawings

Once planning is approved, we produce detailed construction drawings showing exactly how your project should be built — covering structure, thermal performance and fire safety in line with building regulations.

06

Building regulations

We complete all relevant paperwork and submit your application to building control, dealing with the application through to full or conditional approval. Structural calculations from a structural engineer may also be required.

07

Revisions

Up to three sets of revisions to the construction drawings are included in your quotation. Any further revisions or changes beyond the agreed scope will be charged at £50/hr.

08

Get building

With planning approved and building regulations in place, you're ready to go to tender and appoint a builder. We recommend asking friends or neighbours for recommendations, or using Facebook community groups for local referrals.

Not sure which service you need?

Does your project need planning permission?

Many extensions and loft conversions can be built under Permitted Development rights — without submitting a planning application. If that's the case for your project, you may not need YPDS's full service.

Our sister site permitted-development.com provides instant, fixed-price architectural drawing packages for PD projects. Browse, pay and download — no consultation needed.

What qualifies as permitted development

Single-storey side extension
Two-storey rear extension
Loft conversion
Garden room / home office
Garage conversion
Outbuildings & garages
Porch

PD rights do not apply to flats, maisonettes, conservation areas, listed buildings or some new-build developments. Contact YPDS if you're unsure — we're happy to advise.
