Planning permission for a garden plot in Colwyn Bay

A planning application for a new home in a Colwyn Bay garden goes to Conwy County Borough Council, and its officers will judge it on access, privacy, daylight, character, parking, bins, trees and drainage. We prepare the application so each of those questions has a clear, evidenced answer before it is asked.

The service covers the measured survey, specialist reports, drawings, design statement, forms, ownership certificate and fee, followed by management of the application through consultation to a decision. You keep the land throughout, and once permission is granted, the choice to build, sell or simply hold the plot is yours.

Before you decide in Colwyn Bay

Overshadowing is a common objection to garden homes, so we answer it with numbers. At noon on 21 March the sun over Colwyn Bay is about 37° above the horizon, and the shadow from a 5 m eaves line reaches about 6.7 m; on 21 December the sun rises to only about 13°.

Using those angles, we model shadows across neighbouring gardens and windows and adjust the height, position or roof shape of the new home until the effect is acceptable. Conwy County Borough Council can then judge the scheme on evidence rather than impressions.

This section is worked out for the latitude of Colwyn Bay: around 37° of sun at midday in late March and about 13° at midwinter. It shows why the gap between your house and a new home behind it is about light as well as privacy. Garden assumed to face north.

From first call to decision

If you already have outline permission or a full permission with conditions for a plot in Colwyn Bay, we can take it from there. We check what still needs approval, prepare reserved matters or condition details, and submit them. Then you can move on to the build with us, sell the plot, or hold it while you decide.

  1. Free plot appraisal

    We review the title plan, access, constraints, policy and planning history around your address, then talk it through with you. If the plot looks viable we visit, and tell you plainly whether an application is worth making.

  2. Surveys and design

    A measured survey comes first, followed by the specialist surveys the plot needs, such as trees or ecology. The layout is designed around access, privacy, daylight, parking, bins and garden space for both homes.

  3. Pre-application advice

    Where policy is tight or the plot unusual, we put a draft scheme to the council’s planners first. Their written response shows which issues to fix before you pay the full application fee.

  4. Submit and manage

    We complete the forms, ownership certificate, drawings and statements, pay the fee on your behalf and submit. During consultation we answer officers’ questions, respond to consultees and agree amendments where they help.

Worth checking early

  • Permission doesn’t override private rights: covenants, ransom strips, sewer easements and party wall matters still need dealing with separately.
  • Neighbours have a formal say during consultation, and the council must weigh any planning objections they raise.
  • Conditions can add cost and work before building starts, such as approved drainage details, tree protection or a construction management plan.

Your questions, answered for Colwyn Bay

Can I sell my Colwyn Bay garden plot once it has planning permission?

Yes. Planning permission stays with the land, so the plot can be sold with it and the buyer can build the approved scheme, subject to any conditions. The plot will need its own title through a transfer of part at HM Land Registry, and any mortgage lender will need to release it. Take advice from a tax adviser before selling.

How long will my Colwyn Bay garden plot application take?

The statutory period for a minor application, such as one or a few new homes, is 8 weeks from validation, in both England and Wales. Many take longer, and the council may ask you to agree an extension in writing. If no decision is made in time and no extension is agreed, you can appeal for non-determination.

How close to neighbours can a new home in Colwyn Bay be?

It depends on the council’s guidance and the window layout. Many councils use around 21 metres between facing back windows and around 12 to 15 metres between a back window and a blank side wall, but the guide used by Conwy County Borough Council decides. Screening, levels, roof form and window positions can all change what is acceptable.

Does a garden plot application in Colwyn Bay need a tree survey?

Often, yes. If trees on or near the plot could be affected, councils usually expect a tree survey showing root protection areas and how they’ll be protected during building. Trees with a Tree Preservation Order, or in a conservation area, need consent or notice before any work, and can shape where the house and drive go.
