Before you decide in Blackwood
A new home beside yours affects light to your side windows and your neighbour’s. Around the spring equinox, the noon sun over Blackwood climbs to roughly 38°, and a 5 m eaves line then casts a shadow close to 6.3 m long. By December the midday sun reaches only about 15°, so the same wall shades far more ground.
On a side plot that shadow may fall across your own flank wall or the neighbour’s garden. We model it for your actual plot, and adjust the footprint, roof shape or gap at the side so the new home doesn’t take more light than it should.
What happens next in Blackwood
You stay in control after the appraisal. Selling means heads of terms in writing, read by your solicitor, before anything is signed. Building means survey and design ahead of a written quote. Whichever you choose, Caerphilly County Borough Council receives the application and asks your neighbours for comments, and a decision on a single home often takes a few months, longer if the design needs amending.
Free plot appraisal
We look at your plot on maps, the title plan and street views, check planning history nearby and talk it through with you. If a home beside yours looks possible we visit. No cost, no obligation.
Read the street
We measure the plot and record the building line, the gaps between houses, roof heights, materials and boundary walls, then check where a new drive could go and what drivers would be able to see from it.
Choose your route
Sell the plot outright, sell it subject to planning, or grant an option while you keep your house. Or keep the land and have us design, get planning for and build a new home on it.
Sale or build
For a sale, your solicitor handles the transfer of part and any release from your lender. For a build, a written quote follows design and survey, then we build, arrange the warranty and hand over.
Worth checking early
- A new drive close to a junction may not be acceptable to the highway authority, which can force a different layout.
- Corners kept open by design can be harder to build on than they look; character can matter more than space.
- Attaching a home to yours brings party wall, fire and sound separation work, and changes the feel of your own house.
Your questions, answered for Blackwood
Can I build a house on my corner plot in Blackwood?
Possibly, if a new home would respect the building lines, keep the corner feeling open enough and allow safe visibility for drivers. It needs planning permission, and Caerphilly County Borough Council decides. Our free appraisal tells you whether your corner is worth taking further.
Can you build a home beside my house in Blackwood for my family?
Yes. A home next door can give a parent or grown-up child their own front door while keeping them close. You keep the land; we draw the house, apply for permission, build it and arrange the structural warranty or other cover lenders accept. The written quote comes after design and survey.
Could I sell just my side garden in Blackwood and stay put?
Yes. Legally it’s a transfer of part: HM Land Registry gives the side plot a title of its own, while your house keeps the rest. A mortgage lender has to consent to releasing the plot from its charge. Where the plot suits, we buy with or without planning, subject to survey, title and contract.
Will a new drive near the corner be allowed in Blackwood?
Only if drivers would have a clear enough view of the road and the junction stays safe. The highway authority comments on this and controls new dropped kerbs. Drives very close to a corner are often resisted, so we check the position on site before designing.
