Logo _BC

of SBCH planning permissions are already secured through S106 on large sites, and expected to climb to 75% by 2026.

Challenges Facing Housebuilders.

Limited Economies of Scale

Selling land for SBCH to individuals or third-parties often results in losses of “margin-on-margin” as buyers are unable to match the efficiencies of larger builders.

Policy Complexity

Varied interpretations. of SBCH by local authorities caned costs and administrative challenges, often driving developers toward overly complex and expensive solutions that may not align with market demand.

Milestone Dependencies

SBCH is frequently linked to other site development milestones (similar to Affordable Housing), complicating project scheduling and delivery.

Customisation Delays

Many housebuilders are hesitant to engage directly with individual homebuyers for tailored solutions, which can result in delays and additional costs.

Design Constraints

Traditional self-build models typically require larger plots to accommodate detached homes, forcing housebuilders to compromise on-site density and overall profitability.

Blank Canvas Process for Housebuilders.

1. Data-Driven Layout Design


Leveraging insights from the Right to Build Register, we conduct targeted surveys and engage directly with homebuyers who have registered their demand for SBCH in the area – providing a critical pathway to achieve statutory compliance. Our architects then translate these market insights into multiple layout proposals for your base house model. These designs are tailored to local preferences—whether that means open-plan living, dedicated home offices, or versatile entertaining spaces—and by working within existing structural walls, we keep construction alterations minimal and costs efficient.

2. Selling via the Blank Canvas Portal


Once layouts are finalised, we market the homes on our website, as well as other traditional marketing routes. Homebuyers can view available plots, customise their homes to suit and finalise their reservation – quickly and online!

3. Orders That Kickstart Construction


Every reservation is packaged into an order form for Blank Canvas delivery, providing housebuilders with all the details required to exchange contracts and begin building.

Ensure compliance under Section 106.

Blank Canvas enables housebuilders to seamlessly comply with their Self Build & Custom Housebuilding obligations under Section 106, optimising efficiencies at every stage. Most Local Planning Authorities insist evidence is submitted, detailing how self and custom build housing will be offered to homebuyers. Typically, this info is to be contained in a “scheme, strategy or plan” requested as part of the conditions contained in the Section 106 legal agreement. Adopting Blank Canvas enables full compliance as follows:

Only Custom Build Homes can achieve this while also ensuring the self and custom build specific audience is reached.
