Whitby conservatory replacements, designed and built

A conservatory replacement in Whitby starts with the right design and the right approval route. We take care of both, then build it with our own project management.

Included in a typical project

  • Insulated walls and roof to current regulations
  • Glazing and doors to suit the new room
  • Removal and disposal of the old conservatory
  • Opening widened into the house if wanted

A replacement is a chance to rethink the shape. Many conservatories are oddly proportioned; for a similar cost the new room can often be squarer, wider or better connected to the kitchen.

Planning and approvals in Whitby

In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.

In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.

Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.

If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.

Applications are decided by the local planning authority (your district, borough or unitary council).

Covering Whitby

Site visits are available across Whitby (YO21). Nearby, we also take on projects in Redcar (17 miles), Scarborough (18 miles), Middlesbrough (22 miles), Northallerton (33 miles).

Just over the County Durham border, Thornaby-on-Tees is about 24 miles away. Homes across Yorkshire and the Humber range from back-to-back and through terraces to large suburban semis, and extension options vary with them.

Our process, step by step

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

  1. Free site visit

    First, a site visit: we look at the house, garden, access and drains and listen to what you need.

  2. Design and approvals

    Drawings are prepared and agreed with you, then submitted for the right planning route and building regulations approval.

  3. Fixed written price

    We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.

  4. Build and sign-off

    We build it with one project manager, book the building control inspections and hand over the completion certificate.

Your questions about a conservatory replacement in Whitby

Can I see a price before committing to anything?

Yes. The guide prices on this page are adjusted for Whitby, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.

How long does a conservatory replacement take to build in Whitby?

On site, typically 8 to 14 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.

Who do I contract with for a conservatory replacement in Whitby?

Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.

Can I keep the existing base?

Sometimes, but conservatory bases are often too shallow for solid walls. Trial holes tell us before we confirm the price.

Does replacing a conservatory need planning permission?

A solid replacement is treated as a new extension, so it must meet the permitted development limits or get planning permission, and it always needs building regulations approval.
