01 / EXTRA STOREY AND ROOFTOP TERRACE
A full extra storey.
Your own space above it.
The low attic could be replaced with a full-height storey in a lightweight structure, such as timber. The concept provides an apartment of approximately 50 m², with an open terrace of approximately 50 m² above it. The two existing apartments can be refreshed independently of the extension.
Access to the roof is via the extended shared staircase on the garden side, ending in an enclosed, lockable roof exit. The terrace has a solid, opaque parapet, without glass balustrades or an overhead canopy. From the street, it presents a simple roofline.

CONCEPT, not an approved design. The area, structural capacity, planning conditions, fire safety and feasibility of a third dwelling require professional confirmation. A solid parapet alone does not establish legal compliance. The extension and terrace are not included in the house price.
See the scope and estimated costs ↓CONCEPT / NEW FLOOR LAYOUT
From the shared staircase
to your terrace above the city.
A living room with kitchen, a bedroom, a bathroom and storage. The new apartment is entered from the shared staircase on the garden side. The same staircase continues up to the roof.
There are no private internal stairs within the proposed apartment. Its approximately 50 m² area is an assumption; the shared staircase is outside that area. This is a functional diagram, not a survey or construction design. Exclusive use of the terrace must be established in the property documents.
02 / ABOUT THE PROPERTY
Close to each other.
Space of your own.
Two apartments, each with its own kitchen and bathroom, connected by an internal shared staircase.
The layout gives a multigenerational family flexibility. You could also live in one apartment and rent out the other. A garden, integral garage and full basement provide space for everyday life, storage and your own plans.
According to the owner, this semi-detached house needs refreshing, and its installations have been renewed. Keep the layout or bring your own style to the interiors. The photos show the current condition; the visualisations explore a possible change.

Questions worth asking
Are two legally separate apartments being sold?+
The entire property is for sale. The two apartments are functionally independent. Creating separate legal titles and selling them individually requires a document review and the appropriate formalities.
Does the 50 m² rooftop terrace already exist?+
No. A 50 m² apartment with a separate 50 m² terrace on its flat roof is a proposed extension concept. The existing first-floor terrace is 11.55 m² according to the listing. The current attic is low, approximately 1.30–1.50 m high.
Which documents should be checked?+
The current land and mortgage register, land tenure, building documents and measurements. The seller reports having a certificate converting perpetual usufruct into ownership. Current entries and arrangements for discharging any encumbrances require verification before signing.
What determines whether an extra storey can be built?+
Current planning provisions for the plot, a structural assessment, access to the new floor and terrace, and required approvals. The property materials refer to planning area 27MW. That designation alone does not confirm permission for a particular project.
When can I view the house?+
Viewings are scheduled only for 12–13, 19–20 and 26–27 September 2026, with an appointment required. The listing indicates handover from 30 October 2026, subject to agreement at the transaction.
POSSIBILITIES / TODAY AND TOMORROW
Two apartments today.
Potential for three.
Choose how you would use the house.
Discuss the extension scope with your designer.
For family
Two households, their own kitchens and bathrooms, one shared address and garden. Refresh the interiors in stages.
Live here and let
One apartment for you, the other to rent out. The separate layouts offer flexibility without an immediate extension.
Explore its potential
Consider another apartment on a full-height new floor with a rooftop terrace. Separate legal titles and individual sales require an additional assessment.
SCOPE AND BUDGET
What should you budget
for the changes?
Indicative gross ranges include materials, labour and a 10% contingency, without furniture or appliances. They assume a straightforward lightweight structure and sound existing building elements.
Refresh both existing apartments
PLN 45–65 thousandPainting and flooring. Existing installations are retained.Extra storey without a terrace
PLN 299–410 thousandApproximately 50 m² ready for finishing, including design and roof.Extra storey with a terrace
PLN 366–520 thousandThe same scope plus an approximately 50 m² open terrace and access from the shared staircase.The terrace option already includes the extra storey: do not add those two prices together. Refreshing the existing apartments is a separate item. The base roof and new-floor installations are each counted once.
What does “refreshing” include?
Painting walls and ceilings, replacing floor finishes, skirting and local repairs. According to the owner, water pipes and electrics have been renewed and the heating system has a new boiler. The base scope excludes the basement, garage, common areas, windows and furnishings.
What does the terrace cost cover?
The 50 m² timber deck alone is approximately PLN 20–30 thousand before contingency. The complete terrace increment is approximately PLN 68–110 thousand including contingency: this also covers roof loading, waterproofing protection, a solid parapet and extension of the shared staircase.
This is a concept-stage budget, not a contractor’s quote. The extra storey requires a favourable structural assessment and confirmation of legal feasibility. Major structural reinforcement or utility supply upgrades may cost extra. Refreshing the existing facade and finishing the new apartment are optional items in the detailed estimate.

The data sample retrieved for the immediate neighbourhood did not contain records from which we could calculate a local median. We therefore do not present one as a fact. No records in this sample does not mean there were no transactions.
No verified matched pair of otherwise identical 50 m² apartments, one with a 50 m² roof terrace and one without, was found. We therefore do not assign an automatic percentage premium to the terrace. View current Grochów listings ↗
