The local picture in Hatfield
Bungalow plots in AL9 and AL10, as anywhere, come in many shapes: some are long and narrow, some wide and shallow, some on corners or bends. That is why we measure your plot on the ground rather than working from averages or maps alone.
The policies in the council’s Local Plan set the tests Welwyn Hatfield Borough Council applies to new homes on garden land. Its design guidance usually adds detail on spacing, building lines and roof heights, and those details matter a great deal on a single-storey road where one tall roof stands out.
How we’d take it forward in Hatfield
Tell us roughly where your Hatfield bungalow is and how the plot is laid out. We check the title plan, the planning history nearby and the street from the desk, then talk through what you want from the land. If it looks viable, we visit, measure and sketch the options for you to consider, with no cost and no obligation at any point.
Free plot appraisal
We look at the plot’s width and depth, the access, the planning history nearby and the character of the street, then talk through what you want. It’s free, with no obligation, and a site visit follows if it looks viable.
Choose your route
You can sell a plot and stay put, sell subject to planning, grant an option, enter a joint venture, or keep the land and have us design, get planning for and build a new home on it.
Planning application
We prepare drawings and reports designed around single-storey neighbours and the street scene, usually seek pre-application advice, and submit. The council consults neighbours and makes the decision.
Sale or build
If you sell, your solicitor handles the transfer and any lender release. If we build, you receive a written quote after design and survey, and the new home is built and handed over to you.
Worth checking early
- You’ll keep a smaller garden, and a drive alongside your bungalow brings cars past your windows.
- Filling the gap beside a bungalow can change the look of the street, which councils weigh carefully.
- A two-storey home on a road of bungalows is often resisted, so designs may need to stay low.
Your questions, answered for Hatfield
Do I need to sell my Hatfield bungalow to develop the plot?
No. You can keep the bungalow and sell a plot, have us build on the land for you, or enter a joint venture. Replacing the bungalow is only one of several options, and staying put is often simpler.
Could I build a home for a relative on my bungalow plot in Hatfield?
Yes, through our design and build route. You keep the land, and we design, get planning for and build the new home. A separate home needs planning permission; an annexe used as part of the main house is treated differently.
Will Welwyn Hatfield Borough Council allow a two-storey house next to bungalows in Hatfield?
It depends on the street and the design. Councils are often cautious about two-storey homes among single-storey neighbours because of overlooking and the change to the street. Chalet designs with rooms in the roof are a common compromise, but the council decides.
Can I sell part of my bungalow garden in Hatfield and stay living there?
Yes. You keep the bungalow and sell the land behind or beside it, with or without planning, subject to survey, title and contract. If the bungalow is mortgaged, the lender must agree to release the plot. Take tax advice before you sell.
